Physics is the branch of science in which we study about nature and its laws. Therefore it is real and no one has the authority to frame the rules of physics. All the events in the nature follow some basic laws and revealing these laws from the observed events is physics. Physics is concerned with the basic rules which govern all the domains of life.

Physics is also defined as interaction between physical systems. It concerns with making desperate attempts tocalculate the reality through mere observations encapsulated with reasons and logics. The absolute aim of physics is to formulate precise prototype of the physical reality. This helps to develop fundamental rules which precisely describe its function. These rules become βlaws βover a period of time if not proved wrong.

Hence it is a crucial part of the education system and is the building block of the future technology. Without proper understanding and sound knowledge of this subject it is impossible to talk about innovation and sustainable development.

Physics has been classified into two parts, namely classical physics and modern physics. Classical physics (before 19 century) includes Newtonian mechanics and Maxwellβs electro mechanism, whereas modern physics (after 19 century) includes relativity and quantum mechanics.

- Physics Question
Instructions

In a two-page paper, identify the physics principles contained within the following scenario. Explain how these principals connect to Einstein’s theory of relativity or in modern applications in physics. If you use a GPS option on your car or a mobile device, you are using Einstein’s theory of relativity. Finally, provide another example from your own experience, then compare and contrast your scenario to the provided example below.

Scenario

Mandy took a trip to Rome, Italy. She gazed out over the open ocean 20,000 feet below as her airplane began its descent to her final destination of Rome. It had been a long flight from New York to Rome, but as she stretched, and her bones creaked as though she was old, she knew that in fact, she was a tiny bit younger than her compatriots back home, thanks to traveling at hundreds of miles per hour. In fact, time for her was running slowly compared to her friends in New York for two reasons: the speed at which she had traveled and the height of the airplane above the Earth. Neither, though, were noticeable.

## Physics Question

## Energyyyyy

Describe some possible energy conversions occurring in the following scenarios. Include as many conversions as you can, with a minimum of two per scenario.

a) Musicians from the Florida Orchestra playing music for a full theatre that enjoys the soiree.

b) A comedy program being recorded and broadcasted live for a national audience at home watching TV.

Hint: Use the names of the 5 basic forms of energy (in the slides) when explaining any specific energy conversion.

Energy forms

The forms in which energy comes are the result of the four fundamental forces in nature β gravitational, electromagnetic, and nuclear (weak and strong). Energy can be categorized into 5 forms: 1- mechanical, 2- chemical, 3- radiant, 4- electrical, and 5- nuclear.

1-Mechanical energy is the most familiar form of energy. Ex: a car moving (kinetic energy) or water behind a dam (potential energy). Sound is another example.

2-Chemical energy is the form of energy involved in chemical reactions. Ex: photosynthesis, burning wood. Our digestion is another example.

3-Radiant energy is energy that travels through space, even if it is empty. Ex: sunlight, X rays, microwaves, FM, TV signals. All of them are electromagnetic radiation.

4-Electrical energy comes from the electromagnetic interactions of matter. Ex: electrical current at home, car battery.

5-Nuclear energy comes from the innermost part of the atom, its nucleus. Ex: nuclear fusion in stars, nuclear fission in a power plant.

5) Data collection video:Iβll send you the link - I design an efficient solar shower. I put the problem and goals, and need your help in some solutions. (details below)
Define the problem:

Considering building a solar shower in the desert, the mountain, a forest, or a remote area where no gas or electricity is available, define the goals for what should be done and list criteria for success of each goal. (You certainly want your solar shower to work as efficiently as possible.)

Location:

Lake Tahoe, we will use the snow during the winter and the lake water in the summer as the source of water for our shower. The shower will be attached to the side of our cabin in a place that has direct sunlight year round.

Goals:

We will make a storage reservoir to keep extra water warm using a plastic container with a glass lid. The bottom of the container will also be black to help absorb more sunlight. The storage container will be located right next to the shower so conserve time it takes to transfer water to the shower. The water can be transferred via buckets to the shower reservoir.

The shower will be lined with plastic panels on the inside and will be dark/black. The outside will be wood and the floor or the shower will be made of some sort of stone to allow the water to run off. The top of the shower will be able to hold approximately 5 gallons (41 pounds) of water at one time. There will be a shower head and a valve to be able to stop and start the flow of water manually.

We want the water to be warmed during the entire day so that it can be used in the evening/night. Ideally the water (in the top of the shower) will stay warm for a couple of hours after sunset. Any remaining water will be reheated the next day. For cloudy days the storage container may be used and the water should stay warm enough to use for up to 2 days with our available materials.

2. Write an explanation in two parts for why your design will work efficiently; that is, (a) why will your design do a good job of initially warming the water and (b) then keeping it warm until shower time? Focus on how your choice of materials/colors (a) maximizes the transfer of energy into the water to warm it up, and (b) minimizes the transfer of energy away from the water to keep it warm. You must explain these in terms of the heat transfer mechanisms: heat conduction, IR radiation, convection, and/or absorption of light.

I attached a screenshot as a PDF for the overview of work!## Environmental loads

In a fjord crossing project in Western Norway, it has been proposed to use a submerged pipe tunnel. The project team envisages two different routes for the crossing. Route A is 4 km long while Route B is 6 km long. The environmental parameters for the two routes are also something different, see under.

| Length | Current velocity | Wave height | Wave periodRouteA | LA = 4 km | UA = 1.5 m / s | HA = 3 m | TA = 6 sRouteB | LB = 6 km | UB = 1.5 m / s | HB = 4 m | TB = 7 s

In both cases, the pipe tunnel is intended to be designed as a circular pipe with diameter D = 16 m, The drag coefficient is given as CD = 1.2 and the mass coefficient is given as CM = 2.0. The density of seawater is 1025 kg / m3.

(a) Assume a constant current velocity in the entire tunnel’s length and determine the total current force for both two routes.(b) Assume that the top of the pipe tunnel is at a water depth of 15 m (to prevent ships from collide with the tunnel). Assume regular harmonic waves, use the wave potential for deep water and determine the maximum particle acceleration and particle velocity at a depth corresponding to the center of the pipe tunnel(c) Use a simplified method and give an estimate of mass force and traction for the pipe tunnels in the two routes. Compare and rank the size of the three power components you have found (mass force and traction from wave, as well as current). Can you say something about what is dominant for the dimensioning of the pipe tunnel?

Explain how these principals connect to electricity, magnetism, or light in modern applications in physics. Finally, consider the different concepts in which James Clerk Maxwell did research, and give an example of one of these concepts in use in your life. For instance, Maxwell’s research led to the development of radio waves. If you listen to a radio, then you are using Maxwell’s research. Provide another example from your own experience, compare, and contrast your scenario to the provided scenario below.

Scenario

Mandy took a trip to Rome, Italy. Once landed and inside the terminal, she turned her cell phone back on, but it was not charged. She found a charging station with a USB adaptor port. The USB was universal, providing 5 volts in any country you were in, and a small red LED next to her phone’s screen told her the phone was successfully charging. This USB port seemed to have very high amperage, meaning it charged her phone quickly. She was aware, though, that almost all of Italy’s electricity was generated by burning fossil fuels, and thus she was determined after this to use the portable solar charger she had bought rather than wall electricity.

## linear vectors and Helbert space

Physics Assignment Help 1 Linear vectors and Hilbert space

D: Linear vector space A linear vector space is a set of elements, called vectors, which is closed under addition and

multiplication by scalars.Using Dirac notation, the vectors are denoted by kets: |k). We can associate to each ket a vector in the dual space

## Discussion Post for Phys 1404

Lunar Effect DiscussionThere are a lot of folklore tales associated with the moon. Some are ancient, some modern. One relatively modern bit of folklore is that crime rates increase during the full moon. The reasoning is that just like tides are caused by the moon, then people (who btw are mostly water) are also affected by the moon. Use your critical thinking skills and respond to this bit of folklore. Address any or all of these questions: Can you formulate a hypothesis and imagine a method to falsify it? What are the variables involved in studying the lunar effect? Can it be tested experimentally? Also, if it were a real phenomena then how can we possibly have free will when the moon would have control of such things? Respond to some or all of these questions.

## potential energy and change energy

A) Find an expression for the electric potential at the point halfway between the two negative charges (in other words, at the bottom center edge of the square). No need to simplify. You will need to use the pythagorean theorem. B) An electron starts from rest at the point described in part A). (Halfway between the two negative charges). It then accelerates towards the center of the square. Find an expression for the kinetic energy of the electron when it reaches the exact center of the square. (No need to simplify, no need to plug in numbers; use the usual constant “e” for the magnitude of the electron’s charge, and me for the electron’s mass.)Don’t forget that the electron has a negative charge!(Hint: save yourself time and effort by referring to your answer from part A.)

If you download the relevant software and attempt to run the simulation and it is still not working, please call the IT helpdesk. It also could be that your computer does not have sufficient space to run the simulation. Please check all the possibilities).

For this experiment, you use the βChartsβ section of the lab. After you click the Charts section of the lab, select the “velocity” and “acceleration” tools (left-hand side). You can change the position, velocity, and acceleration values as per the scenarios given below and relevant graphs will appear on the screen. (Also, note the “record” button at the bottom of the simulation. You can select this function and run the simulation. Then, use the “playback” button to view the experiment again to note the time values for that scenario.) This information constitutes the βExperimental Detailsβ section of the lab report. You must keep a record of the details information of the graphs appearing on the screen as experimental values for each scenario. These values form part of the βResultsβ section of the lab report. Now, complete the theoretical calculations of velocity and acceleration for each scenario using relevant equations. These calculated values also form the βResultsβ section of the lab report.

Now, you can complete the βDiscussionβ section of your lab report by comparing the values and discussing any differences in the theoretical and experimental values and any other information relevant to the experiment.

Using the Moving Man simulation chart section, develop Position v. Time, Velocity v. Time, and Acceleration v. Time graphs for the following scenarios and use them as the experimental results of your lab report (screenshots or take pictures of the graphs, in addition to hand-drawn graphs with actual time values). Remember to explain the graphs, how to calculate velocity or acceleration, and what information can be gathered from the area under each graph in your discussion section.

1. Constant velocity (5 m/s) for 10 m.

2. Constant velocity (-2 m/s) for 5m.

3. Constant acceleration (-2 m/s2) for 10m.

4. Constant acceleration ( 3 m/s2) for 10m.

Please discuss (without using the simulation), the following two scenarios:

1. An object is travelling in a positive direction and change to negative velocity – discuss. What possibilities are there for acceleration values?

2. An object is travelling in a negative direction and change to positive velocity – discuss. What possibilities are there for acceleration values?

N.B.: When operating the simulation, it is better to enter only the velocity or acceleration value for each scenario. Do not enter the position values, since this would change the initial position. You control the position value by stopping the simulation when the man has moved the desired distance.

A planetary system is a set of gravitationally bound non-stellar objects in or out of orbit around a star or star system. Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals[1][2] and circumstellar disks. The Sun together with the planetary system revolving around it, including Earth, forms the Solar System.[3][4] The term exoplanetary system is sometimes used in reference to other planetary systems.

2. Plot πΉ(π)π£π .πF(r)vs.r . Make sure you insert the correct graph! It looks like in inverse-square curve. Label the graph for presentation. Afterwards, run a trendline by right-clicking the data. Chose power fit. Place the equation on the graph and enhance the size. Note the power of the fit. Record and label on the spreadsheet close to the graph the power obtained and the coefficient. Note: Do NOT run a LINEST or linear fit here!!!!!

For this analysis, using the Coulomb equation and this coefficient, calculate π1q1. Record this value in SI based units as well as in micro-Coulombs. Also, record the polarity. Is it is negative or positive ion? How do you know?

4. Plot πΉ(π)π£π .1π2F(r)vs.1r2. Is it linear? Label the graph for presentation. Run a LINEST by highlighting a 2 x 5 matrix starting around cell A15 or so. Record the value of the slope and the uncertainty (e.g. 2.5Β±0.12.5Β±0.1).

For this analysis, using the slope and the Coulomb constant, calculate π1q1. Record this value in SI based units as well as in micro-Coulombs. Also, compare with your first calculation and comment.

Part III (Create a tab called “summary”): Insert large text boxes to type in.

In the summary tab, address these questions:

From the data (you) collected, does the power fit indeed illustrate the inverse-square Law?

Suppose you placed another charge (π3q3) on the opposite end of the ruler of (a) equal value as π1q1and with the same sign and (b) a charge π3=2π1q3=2q1 .

Describe how the force on π2q2 would look as a function of position starting at the original point as before, and then moving towards the right for both scenarios (a) and (b)? Analyze one scenario at a time! Take a stab at it. How would you begin to investigate this?

Suppose you were in a lab doing these measurements, assuming well-calibrated equipment, list some random errors you would encounter.4)Video 2:

## velocity question

A proton is flying through space with a velocity of 100,000 m/s. It starts off in a region of space with no electric potential, heading for a different region of space with a 40-Volt electric potential. Solve this problem using conservation of energy. Look up the charge and mass of the proton as needed.

A) Show a calculation which determines whether or not the proton can make it to the 40-Volt region.

B) If the proton *can* make it to the 40-Volt region, find the proton’s final velocity when it gets to this region. But, if the proton *cannot* make it, instead find the highest electrical potential it can get to (before it stops).

## physics home work

Physics Assignment Help An electron is traveling horizontally with speed vx= 40 km/swhen it passes into a region of uniform, downward electricfield with magnitude E = 950 N/C. The field is generated bytwo horizontal plates with equal (and opposite) charges thatare separated by a distance d = 2.5 mm. When the electronenters this region, it is midway between the two plates. Whatangle ? does the electronβs velocity vector make with respectto the horizontal when it crashes into one of the plates? Forthe limits check, investigate what happens to ? as the platesbecome extremely close together (d ?0). Note: the effects ofgravity can be neglected in this problem.

## Physics Question

Instructions

In a two-page paper, identify the classical physics principles contained within the following scenario. Explain how these principals connect to work done by Galileo or Newton. Finally, consider the different fields in which Galileo and Newton did research, and give an example of one of these fields in use in your life. For instance, Newton developed the field of optics. If you wear glasses or contact lenses, you are using Newton’s physical optics theories every day. Aside from glasses or contacts, how do the theories of Newton or Galileo affect you in your daily life?

Scenario

Mandy took a trip to Rome, Italy. She gazed out over the open ocean 20,000 feet below as her airplane began its descent to her final destination. She could watch the Sun setting in the west. Over the Eastern horizon peeked a full moon, just rising, displaying its cratered face. As the plane neared the ground, Mandy could not help but think that she was in a giant metal object hurtling through the sky. Without the specific shape of its wings, the plane would fall to the ground no differently than a large metal projectile.
