Antwon made a table to study some simple machines. which best describes how to correct the error in the table? a remove "can also be used to lift objects" from the description of a screw. b add "looks like two inclined planes placed back-to-back" to the description of a wheel and axle. b move "reduces friction when object is being moved" to the description of a pulley. d change "decreases distance" to "increases distance" in the description of an inclined plane.

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.
