Question 2

A deep-space exploration probe is powered by a Radioisotope Thermoelectric Generator (RTG) containing plutonium-238.

At the launch of the mission, the RTG is loaded with 3.20 kg of plutonium-238.

The thermal power density of pure plutonium-238 is 0.55 W g^-1.

Plutonium-238 has a half-life of $years87.7\text{ years}$ .

Calculate the rate of heat energy released by the RTG (in watts) after a duration of $years263.1\text{ years}$ .
