A 140g ball, in horizontal flight with a speed v_(1) of 39.0 m/s. is sturck by a bat. After leaving the bat, the ball travel in the opposite direction with speed v_(2)=39.0 m//s . If the impact time Deltat for the ball-bat collision is 1.20ms, what average net force acts on the ball

The ionisation potential of mercury is 10.39 V. How far an electron must travel in an electric field of 1.5 xx 10^(6) V//m to gain sufficient energy to ionise mercury ?

The plates of a parallel plate capacitor are charged to a potential difference of 117 V and then connected across a resistor. The potential difference across the capacitor decreases exponentially with to time.After 1s the potential difference between the plates is 39 V, then after 2s from the start, the potential difference (in V) between the plates is
