Question

The sun radiates about 3.6 x 1026 joules of energy each second. How much mass does the lose each second? Show all of your work and be sure all numbers must be clearing identified and explain in your work.

Answer 1

E=mc^2

hence m= E/c^2
= (3.6x10^26)/(9×10^16)
= 4x 10^9 kg

Answer 2

The lost mass is
`4*10^(9)\ kg`.

Step-by-step explanation:

Given that,

Energy
`E= 3.6*10^(26)\ J`

Using Einstein's mass energy equation

`E = mc^2`

Where, m = lost mass

c = speed of light

E = energy

We substitute the value into the formula

`3.6*10^(26)=m*(3*10^(8))^2`

`m=(3.6*10^(26))/((3*10^(8))^2)`

`m =4*10^(9)\ kg`

Hence, The lost mass is
`4*10^(9)\ kg`.
