Determine the force that the two plates of an (effectively infinite) parallel plate capacitor exert on each other. (You may not have thought about this, but the two plates clearly attract each other. If they weren't mechanically held apart, they would collide.) Hint: If you find the quick way to do this problem (which involves energy), it will only take one line.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

One object has a mass of 1 kg and another object has a mass of 3 kg. if the speeds are the same, which of the following is true about their kinetic energy?
