Sphere A has a mass of 4.2 x 10-2 kg and is tethered to a wall by a thin thread. Sphere A has an
excess of 1.2 x 1012 electrons. Sphere B has a deficit
of 3.5 x 1012 electrons and is 0.23 m from sphere A.
Determine the angle between the thread and
the wall.

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.
