a satellite is powered by nuclear generator that puts out 15 w.how much mass is converted into energy in 10 years life span of the generator?

Answer»

15W = 15 J/s, Energy = 15 W × 10Y × 365.25 d/y × 24 h/d × 3600 s/h

E = mc2

= 4.73×109J

Then, solving for MASS, m = Energy/c2

= 5.26×10-8 KG = 53 μg
