4. A very long wire of carries a current I whose magnitude is increasing at 2 A/s in the direction. shown. The loop on the right is made of copper with a resistance of 1 Q2/m, a length of 1 m and a width of 5 cm. 1 m a. What is the magnitude of the induced current in the loop on the right? For simplicity's sake you may assume that the magnetic field is uniform over the loop.

can i get the answers to part a  part b  part c and part D

I solved for part a and part b which asked part a) The plane flies at 554 miles per hour, relative to the skyscraper. If Casey throws the ball to Matt at 23 miles per hour, relative to the plane, then what speed will Myles see the ball move at? (I got speed of 577 miles per hour). For part b they asked "Matt subsequently tosses the ball back to Casey, at 25 miles per hour. What speed does Myles see the ball move at? (I got 529 mph)   now I need help with part c and part d. part c) Lets's imagine that instead of an airplane, Casey and Matt are on a rocketship, traveling at 93% of the speed of light. Additionally, Casey and Matt have been training very hard and so can toss the ball incredibly fast. If Casey throws the ball to Matt at 25% of the speed of light, relative to the rocket, then what speed will Myles see the ball move at?   part d) Did you use Galilean Relativity or Special Relativity to compute the speeds in part a-c? Why did you choose to use the equation you chose for each…

4.1: 7) At noon, ship A is 20 nautical miles due west of ship B. Ship A is sailing west at 17 knots and ship B is sailing north at 20 knots. How fast (in knots) is the distance between the ships changing at 5 PM? (Note: 1 knot is a speed of 1 nautical mile per hour.)
