A scientist is considering polonium-210 as an energy source for a thermoelectric device that will produce 140 W of power for a spacecraft. Each atom of polonium-210 will naturally emit a high-energy alpha particle with a mass of 6.64 × 10–27 kg. Will a single gram of polonium-210 that produces 1.80 × 10–3 J every hour be enough to power the spacecraft?

A. No, it will not power the spacecraft because power and energy are equivalent.
B. Yes, it will power the spacecraft because power and energy are equivalent.
C. No, it will not power the spacecraft because power is computed as energy per second.
D. Yes, it will power the spacecraft because power is computed as energy per second.
