I need some help with A and B please

Problem 9: Consider a lightning bolt carrying a 19500-A current through a voltage of 0.95 x 102 MV and lasting 0. 75 ms. Part (a) What energy, in joules, is dissipated by the lightning bolt? Numeric : A numeric value is expected and not an expression. E= Part (b) What mass of tree sap, in kilograms, could be raised from 18.0C to its boiling point and then evaporated by this energy, assuming sap has the same thermal characteristics as water (specific heat of 4186 J/(kg.K) and heat of evaporation 2256 kJ/kg)? Numeric : A numeric value is expected and not an expression. m
