Question Get Answer Simulation Link : https://phet.colorado.edu/en/simulation/legacy/collision-lab Q1. start our experiments with the Sun and the Earce changes as the Earth orbits around the Sun. (a) Describe your observations using Newton’s law of universal gravitation. (b) Pause the simulation, and double the mass of the star. How does that affect the gravitational force? (c) Click on the path and then run the simulation and observe how the gravitational force changes when the Earth rotates around the Sun. Explain your observations using equations pertaining towards Universal Gravity and Orbits. (d) First, reset the simulation then pause it. Double the mass of the Earth. How does that affect the gravitational force? (e) Turn the path on and then run the simulation and observe how the gravitational force changes when the Earth rotates around the Sun. Explain your observation.

## An AC circuit with a total resistance of R (15.0 Ω) has an rms current

Question An AC circuit with a total resistance of R (15.0 Ω) has an rms current of I (6.0 amp). The circuit wraps around an iron core transistor with 50 loops. The secondary coils, leading to a different circuit, wrap with N (20) loops. The secondary circuit has a total resistance of 40 Ω. What is the rms current in the secondary circuit?

## A tennis ball “A” is released from rest down a 10.0 m long inclined

Question A tennis ball “A” is released from rest down a 10.0 m long inclined ramp with a uniform acceleration of 5.0 m/s2 . Another tennis ball “B” is initially located at the same height as ball “A” right above the lower edge of the ramp. Ball “B” is thrown upward with some initial speed at the same instant as the release of ball “A”. a) What was the initial velocity of ball “B” so that “A” and “B” reach the bottom of the ramp at the same time?b) Sketch position and velocity time graphs for ball “A” and “B” using the same chart.

## 1)A positive charge of 4.80 μC is fixed in place. From a distance

Question 1)A positive charge of 4.80 μC is fixed in place. From a distance of 4.30 cm a particle of mass 6.00 g and charge 3.90 μC is fired with an initial speed of 76.0 m/s directly toward the fixed charge. How close to the fixed charge does the particle get before it comes to rest and starts traveling away? 2)A charge Q1 = 1.13 μC is at rest and is located 2.30 cm away from another fixed charge Q2 = 1.85 μC. The first charge is then released. Calculate the kinetic energy of charge Q1 when it is 5.10 cm away from charge Q2. 3)
