Answer:
g ≈ 7.4 m/s²
Explanation:
The acceleration due to gravity on planet XX is ...
g = GM/r² = (6.67·10^-11 × 4·10^22)/(6·10^5)^2
g ≈ 7.4 m/s²
Electrical energy is the starting and final energy of a battery
This question is poorly stated, but I assume you mean what conditions are needed. It would have to be cold outside, correct?
