Two trolleys with given masses move at a velocity of 3m. s-1 to the right. the trolleys are connected by a compressed spring that is released to separate the trolleys, such as that the velocity of b increases from 3m. s-1 to 6m. s-1 in the same direction. 1.calculate the new velocity of trolley a​

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.
