Our sun has a power of 3.82·1026 W. So what is the mass loss per second?
Note: [W] = [J/s] = [kg·m2/s2]
Solution: - According to Einstein holds E=m·c2 or ΔE=Δm·c2
- c is the speed of light, 300'000 km/s
- Transform the Einstein equation according to m or Δm
- Δm = ΔE/c2
- Δm = 3.82·1026[kg·m2/s2]/(300'000'000 m/s)2 = 4.24·109 kg
The loss of mass per [translation unavailable] (!) is thus 4.24·109 kg or approx. 424 millions of which:.
