Assume that the turbines at a coal$-$powered power plant were upgraded resulting in an improvement in efficiency of $5\mathrm{.}94\%.$ Assume that prior to the upgrade the power station had an efficiency of $45\%,$ and that the heat transfer into the engine in one day is still the same at $3\mathrm{.}03{10}^{14}J.$

$($a$)$ How much more electrical power is produced due to the upgrade?

kW

$($b$)$ How much less heat transfer occurs to the environment due to the upgrade?

J
