A remote scientific weather station in Antarctica is powered by a small Radioisotope Thermoelectric Generator (RTG).
The RTG uses the thermal energy released from radioactive decay to generate electrical power to run the station's instruments.
This RTG has an efficiency rating of 6%.
Calculate the useful energy transferred by the RTG when 4500 J of thermal energy is released in the decay.
Use the equation:
efficiency=(useful energy transferred by the device)(total energy supplied to the device)×100% \text{efficiency} = \frac{(\text{useful energy transferred by the device})}{(\text{total energy supplied to the device})} \times 100\% efficiency=(total energy supplied to the device)(useful energy transferred by the device)×100%
