The power of the sun's radiation is 3.83x1026W. How much mass does the sun lose in one hour.?

Answer 1

In one hour, that's

3.83 x 10^26W (1J/1W.s)(3600s) = 1.3788 x 10^30 Joules

E = mc^2

m = E/c^2

m = 1.3788x10^30J / (299,792,458 m/s)(299,792,458 m/s)(1J/1kg.m^2/s^2)

m = 1.534 x 10^13 kg

Answer 2

The good and very smart Dr Grayce explains it here:

Apparently, its only about 4 million metric tons per sec.

He** if I lost that much I would have them abbs all the youngens is a huntin fur!

Answer 3

This is the worlds most famous equation.

E=-mc^2

m=E/c^2

Watts is Joules (energy) per second. x 60 is joules per hour. You know E, you know c, solving will get you the mass lost in an hour.
