Imagine you are on the top of a mountain with four basketballs. The mass of the four basketballs are 1,000 kilograms, 200 kilograms, 300,000 kilograms, and 40,000 kilograms. If the basketballs rolled down the hill, which one would supply the greatest force at the bottom of the mountain

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

The movement of electrons between atoms is called an
