## College Physics (4th Edition)

(a) Work is done at the rate of $3600~J/s$ (b) $Work = 5.4~J$
(a) We can find the power delivered by the electric organs: $P = V~I$ $P = (200~J/C)(18~C/s)$ $P = 3600~J/s$ Work is done at the rate of $3600~J/s$ (b) We can find the work done during one pulse: $Work = P~t$ $Work = (3600~J/s)(1.5\times 10^{-3}~s)$ $Work = 5.4~J$
