A resistor RR and another resistor $3\mathrm{.}00$ RR are connected in series across a battery.

Part A

If heat is produced at a rate of $15\mathrm{.}0$ WW in RR$,$ then in $3\mathrm{.}00$ RR it is produced at a rate of

$135$ WW $\mathrm{.}45\mathrm{.}0$ WW $\mathrm{.}15\mathrm{.}0$ WW $\mathrm{.}5\mathrm{.}00$ WW $.$
