$1.$ A loop of wire $($ r $=4\mathrm{.}8*10^-2*$ n $)$ is placed in a varying B$-$field. Initially, B$(0)=8$T and the B$-$ field decreases according to d$/$dx $($theta$)=-0\mathrm{.}6$theta $*$ r$/$sa$.$ Determine the direction of inducted current in the loop $($cw or ccw$).$b$.$ If the resistance in the loop is $0\mathrm{.}160,$ determine the power that is dissipated in the loop.
