hey i need help with this please include units

2. [010.5 Points] DETAILS PREVIOUS ANSWERS The potential across a capacitor is given by V(t) = 12 12'2'1-13t where V is measured in volts and t is time in seconds. when is the potential changing at 4 volts per second? Be accurate to 2 decimal places. Include units. 6.73 seconds x The potential across a capacitor is given by V(t) = 12 12.2-'1-13t where V is measured in volts and t is time in seconds. Find V'(t) at the instant when V(t) = 6 volts. Be accurate to two decimal places. Include units. 6.30 voltsfset X
