A 4.6pF capacitor initially uncharged is connected in series with 7.50kohm resistor and an emf source with E=125V[negligible internal resistance]. What is the voltage drop across the capacitor after the circuit is completed?

Aturntable that spins at a constant 74.0 rpm takes 3.10 s to reach this angular speed after it is turned on. find its angular acceleration (in rad/s2), assuming it to be constant, and the number of degrees it turns through while speeding up.
