Asingle-turn circular loop of wire of radius 50 mm lies in a plane perpendicular to a spatially uniform magnetic field. during a 0.10-s time interval, the magnitude of the field increases uniformly from 200 to 300 mt. (a) determine the emf induced in the loop. (b) if the magnetic field is directed out of the page, what is the direction of the current induced in the loop

Explain in physical terms how a microwave oven works. what would happen when you put a conductor in the microwave oven? explain.

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
