Question

The sun produces 3.9 ⋅ 1033 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in 1.55 ⋅ 107 seconds?

Answer 1

Part A: It is given that,

The sun produces 3.9x10^33 ergs of radiant energy per second.

We need to find how many ergs of radiant energy does the sun produce in 1.55 x 10^7 s

Energy produced in 1 seconds = 1/3.9 x 10^33 ergs

In 1.55 x 10^7 s energy produced is : E=3.9/10^33 x 1.55 x 10^7 ergs

= 3.97 x 10^-27 ergs

In conclusion the radiant energy radiated per second 3.97 x 10^27 ergs

Answer 2

`E=3.97* 10^(-27)\ \text{ergs}`

Explanation:

It is given that,

The sun produces
`3.9* 10^(33)\ \text{ergs}` of radiant energy per second.

We need to find how many ergs of radiant energy does the sun produce in
`1.55* 10^7\ s`.

Energy produced in 1 seconds =
`(1)/(3.9* 10^(33))\ \text{ergs}`

In
`1.55* 10^7\ s`, energy produced is :

`E=(1)/(3.9* 10^(33))* 1.55* 10^7\ \text{ergs}\\\\=3.97* 10^(-27)\ \text{ergs}`

Hence, the radiant energy produced in 1 second is
`3.97* 10^(-27)\ \text{ergs}`.
