Amotor lifts a 10,000 n elevator car a distance of 8 m in 6 seconds. a different motor exerting more power would lift a.) the same car the same distance in a greater number of seconds b.) a lighter car the same distance in the same amount of time c.) the same car a shorter distance in the same amount of time d.) the same car the same distance in fewer seconds

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
