]In need some help because I don't know how to answer,please

1) the energy that is stored in a (25 microFard) capacitor is w(t)=12sin^2 377t J. Find the current in the capacitor

2) the voltage across a (100 microFard) capacitor is given by the expression v(t)=120sin(377t)V. Find (a)the current in the capacitor and (b)the expression for the energy stored in the element.
