If a ball is dropped from a height of 10 m, hits the ground and bounces back up to a maximum height of 7.5 m, describe how the Energy Pie Chart would look. (Use fractions and the storage mode)

In the same situation as above, how would the pie chart look at a height of 5 m (after the bounce but before the max height of 7.5)? (Use fractions and the storage mode)



A cart is speeding on a flat surface towards a spring mounted on a wall. As the cart moves, it slows. When the slowing cart hits the spring, it compresses it fully and the cart comes to rest. If the system consists of the cart, spring, and Earth's field, describe the transfer of energy at the initial and final points.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
