Please see the work below.

Work Step by Step

We know that (a) $P=F.v$ We plug in the known values to obtain: $P=0.57\times 10^{-12}\times 22\times 10^{-6}=1.254\times 10^{-17}W$ (b) As $W=Fx$ We plug in the known values to obtain: $W=0.57\times 10^{-12}\times 25\times 10^{-3}=1.425\times 10^{-14}J$
