Acart is set rolling across a level table, at the same speed on every trial. if it runs into a patch of sand, the cart exerts on the sand an average horizontal force of 6 n and travels a distance of 6 cm through the sand as it comes to a stop. if instead the cart runs into a patch of gravel on which the cart exerts an average horizontal force of 9 n, how far into the gravel will the cart roll before stopping? (a) 9 cm (b) 6 cm (c) 4 cm (d) 3 cm (e) none of those answers

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.
