Dump tower is 96 stories tall. a small, 1.2-kg object is dropped over the side of the roof of the tower and accelerates toward the ground. the mass of the planet housing dump tower is 2.7 times the mass of ganymede and the radius of the body is 1.7 times the radius of makemake. you will track the object for its entire fall. each story of this tower is 3.05 meters tall.
how many seconds will it take the object to reach the ground and what will be its impact speed with the ground?

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.
