The plates have a potential difference of 1000 V with the plate that is at a lower potential at -250 V. What is the electric potential in volts at Point 2?

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

Anybody wanna ? (picture included? )

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.
