2 charges of magnitudes -2.0*10^12C and 3.0*10^12C respectively are 5.0cm from each other. Calculate the electric potential at a point between the charges and 2.0cm from the positive charge and; outside the charges and 1.0cm from the negative. (electrode constant k=9.0*10^9Nm^2C^-2)

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.
