2. Calculate the mass of air in a room of floor dimensions 10 mx 12 m and a height of 4 m
if the density of the air is 1.26 kg/m'.

The table below shows the acceleration of gravity on different bodies in the solar system. on which body would a 10 kg lamp has the most gravitational potential energy when lifted to a height of 2 m? a. earth b. mars c. neptune d. uranus

One form of energy can be another type of energy. a. created to form b. transformed into c. destroyed and then created to form

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?
