An ideal gas that goes through a cyclical process on a PV diagram and returns to the location on the PV diagram where it began. analyze changes in temperature and thermal energy of the gas change during the cycle. Analyze transfers of energy through heat and work during various stages of the cycle.

note: including formulas in the analysis would be helpful.

I need part 1, 2, and 3 answered please just google PhET Masses and Springs Simulations Lab and click the first link. The preview of the lab should be in a box click the arrow/play button in the box and the lab will open

2. Vectors At the base of your screen select ‘Vectors’. This helps in visualizing all vectors at play in oscillation. Select ‘Displacement’, ‘Mass Equilibrium’, ‘Velocity’, ‘Acceleration’, ‘Gravity’ and ‘Spring’. For first run leave Gravity as Earth. Attach 250g mass and observe vectors during oscillation.

(a) At which point is velocity minimum or zero?

(b) At which point is velocity maximum?

(c) At which point is acceleration zero?

(d) At which point is acceleration maximum?

(e) Is Gravity ever zero?

(f) Is spring force ever zero? When?

(g) What happens when Spring constant is increased?

(h) What happens when Gravity is changed to: (1) Moon (2) Jupiter (3) Planet X

(i) Determine value for gravity on Planet X.

3. Lab

At the base of your screen click on ‘Lab’.

Check boxes at top right corner for ‘Natural Length’ and ‘Equilibrium Position’. Select ruler and stopwatch for linear and time measure respectively.

Set Spring Constant and Damping such that Spring Constant is greater than Damping. Select known 100g mass and attach it to Spring. Adjust mass measure to value greater than 250g.

Press red stop button at the side of Spring to stop oscillations.

1. Measure and record value for extension of Spring mass attached.

Pull mass downward away from its equilibrium position for an extension between 10 cm and 20 cm and release to begin oscillations.

2. Use stopwatch to time for ten (10) oscillations. Do two time trials and get average of these two runs.
3. Determine periodic time, T
4. Calculate Spring Constant.
5. Determine energy of spring at the top of oscillation.
6. Determine energy of spring at equilibrium position.
7. Determine energy of spring at the lowest point in oscillation.
8. Determine total energy of system
9. Show that work done on spring is equal to change in spring potential energy: mg∆h = 1/2K(x2) 2 - 1/2K(x1) 2

What can be concluded from the results?

Assume a planet with mass M and radius R.

(a) Find the strength of its gravitational field at the surface, g. [5]

(b) Find the escape velocity, vesc, for a mass on the planet's surface in terms of M and R. [10]

(c) Show that vesc=√2gR . [3]

(d) Calculate the numeric value of the escape velocity from Earth without using Earth's mass. [2]

A mountain climber stands at the top of a 41.5-m cliff that overhangs a calm pool of water. She throws two stones vertically downward 1.00 s apart and observes that they cause a single splash. The first stone had an initial velocity of -1.40 m/s. (Indicate the direction with the sign of your answer.)

(a) How long after release of the first stone did the two stones hit the water? (Round your answer to at least two decimal places.)
s

(b) What initial velocity must the second stone have had, given that they hit the water simultaneously?
m/s

(c) What was the velocity of each stone at the instant it hit the water?

Electrochemical capacitor and battery are electrochemical energy storage system. The former has a very good power density (fast charging/discharging) but low energy density, while the latter has the opposite properties. Please design a device that can have good power density and energy density by combining the electrochemical capacitor and battery. Please provide an equivalent circuit (use -||- to represent capacitor and -©- to represent battery) to describe your design and how they work under charging/discharging conditions. You can use multiple battery and capacitors for your design and explain how it work. Do you think your design can be used to power an electric vehicle to compete with gasoline-based cars?

Consider three particles that interact with internal forces given by ? ⃗ _1→2, ? ⃗ _3→1, etc. The total
force on the system is the sum of these internal forces with any external forces
(? ⃗ _i,ext , ?ℎ??? ? = 1,2,3). By writing out the sum explicitly, use Newton’s third law to prove that
the total acceleration of the system is only due to the external forces.

An 80 cm by 80 cm square loop of wire lies in the xy-plane and has a resistance of 0.2 Ω. It sits in a time-dependent uniform magnetic field of [0.6 sin (3π t)k] T. What is the largest value that the induced current takes on?

Two positive point charges q1 = 6.0nC and q2 = 9.0nC are separated in a vacuum by a distance of 5.36m. The spot on the line between the charges measured from the charge q1 where the net electric field is zero is

What is the classical and relativistic momentum of an object with a mass of 5 kg moving at a speed of 0.8c?

A 35.0g idol made of wood has a Geiger counter placed next to it and found that it emitted 130 decays during a 5.00 minute time frame. How old is the artifact?

There was a demonstration I did our Zoom class with a falling magnet in a simple copper tube. Explain, in detail, the physics behind why the magnet slows its descent through the tube (it does not touch the sides). In your discussion be sure to explain why the magnet doesn't come to a stop in the tube and why it does not speed up. Your response should include at least 3 paragraphs to show your mastery of the material.

A capacitor is fully charged and then connected in series to an inductor with zero resistance wires. This is an ideal L-C circuit that will oscillate the current direction. Explain HOW and WHY this circuit oscillates and discuss energy conservation in this oscillation behavior. Your response should be at least 3 paragraphs to show your mastery of the concepts.

An airplane leaves from city A, located in the east 1500 km from city B. The aircraft has a speed of 500km/h to the east and at the same time it blows a wind of 100km/h from the northeast.
