The temperature of well water be 288.07 K

Explanation:

We have given Heat in house Q_H=13900J

Work done W = 900 J

Efficiency is given by $\eta =\frac{W}{Q_H}=\frac{900}{13900}=0.0647$

Efficiency is also given by $\eta =1-\frac{T_L}{T_H}$ , here T_L is lower temperature and T_H is higher temperature

So $0.0647=1-\frac{T_L}{T_H}$

$0.0647=1-\frac{T_L}{308}$

T_L=288.07K

So the temperature of well water be 288.07 K

The mass of a star causes gravitational pull inwards. The fusion of hydrogen to helium create temperature and pressure which pushes outwards, so basically the forces of gravity and pressure. Possibly nuclear fusion.
