An uncharged capacitor and a resistor are connected in series to a source of emf. If e m f = 10.0 V, C = 18.0 µF, and R = 100 Ω, find the following: a. The time constant of the circuit.
b. The maximum charge on the capacitor.
c. The charge on the capacitor at a time equal to one time constant after the battery is connected.

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.
