How Fast is the Sun Losing Mass Due to Radiation?

In summary, the Sun loses energy at the rate of 3.9*10^24 Watts, which is equivalent to 3.9*10^24 Joules per second. This energy loss is due to radiation and results in a loss of mass according to the equation E = Δmc^2, where E represents energy, m is mass, and c is the speed of light.

Homework Statement


The Sun radiates away energy at the rate of 3.9*10^24 Watts. At what rate it it losing mass due to this radiation?


Homework Equations


E = Δmc^2
E = mc^2 - m0c^2

Where m0 rep. rest mass.

So then the Sun must radiate energy at 3.9*1024 Joule / second.

It will help if you consider a useful time interval, say 1 second, for your evaluation.
 

FAQ: How Fast is the Sun Losing Mass Due to Radiation?

What is the sun's rate of energy radiation?

The sun radiates energy at a rate of approximately 3.8 x 10^26 watts.

How does the sun's rate of energy radiation affect Earth?

The sun's rate of energy radiation is crucial for sustaining life on Earth. It provides the necessary heat and light for photosynthesis and the water cycle, which are essential for the survival of plants and animals.

What factors affect the sun's rate of energy radiation?
