Imagine two billiard balls on a pool table. ball a has a mass of 7 kilograms and ball b has a mass of 2 kilograms. the initial velocity of the ball a is 6 meters per second to the right, and the initial velocity of the balloon b is 12 meters per second to the left. when the two balls hit each other, what will happen if it is a perfectly inelastic collision?

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.

Which statements describe the movement of ocean currents around the globe? check all that apply. strong winds force warm water to sink to the ocean floor. the coriolis effect causes warm and cold water to mix. cool dense water sinks to the ocean floor. warm water replaces cool surface water. wind blowing parallel to the shore causes upwelling of cool water.
