Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

Acar travels in reverse. it covers 150 meters in 12 seconds what is the velocity of the car what is the speed of the car

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?
