For the circuit shown in the figure, the switch S is suddenly closed with the capacitor uncharged. After one time constant, the charge on the capacitor is closest to:
a) 2.0 mC
b) 0.74 mC
c) 1.0 mC
d) 1.3 mC
e) 0.00 mCRelevant Formulas
q = Q⋅(1-e-τ/R⋅C)
τ = RC

A drum (see the figure) has a radius of 0.40 m and a moment of inertia of 6.9kg⋅m2. The frictional torque of the drum axle is 3.0 N⋅m. A 43m length of rope is wound around the rim. The drum is initially at rest. A constant force is applied to the free end of the rope until the rope is...
