Block a weighs 45 n and block b weighs 25 n. a. once block a starts from rest and moves to the right, determine the acceleration if μ between block a and the surface is 0.1. determine the distance traveled and its velocity after 0.5 seconds. b. with μ = 0.1, what should be the new weight of block b so that both blocks a and b will move with constant velocity?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
