(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Suppose we place a perfectly black sphere (i.e., a sphere that absorbs all energy it receives)

with radius 2500 km at a distance of 5.2 AU from the Sun. How much energy does the sphere

absorb in one second?

energy emitted by sun is given to be 3.90 * 10^26

2. Relevant equations

flux = energy emitted(luminosity)/Area

3. The attempt at a solution

I found the area of the black sphere and the area of the energy emitted.

But I do not no what the next step should be. would i need to find the flux of the black sphere first then find how much energy it receives.

I am not looking for a solution to the question but how I would go about trying to solve it.

Can someone please help.
