What power would the solar cell produce if the spacecraft were in orbit around Saturn, 9.5 times as far from the sun

Complete Question

A large solar panel on a spacecraft in Earth orbit produces 1.6kW of power when the panel is turned toward the sun.

What power would the solar cell produce if the spacecraft were in orbit around Saturn, 9.5 times as far from the sun?

The power is  

Explanation:

From question we are told that

   The  power produced by the spacecraft is  

   The distance of the earth orbit from the sun is  R  

     The distance of the Saturn's orbit from the sun is 9.5 R

  Generally the power produced by a solar panel is mathematically represented as

=>    

Here k is a constant

  So

=>      

while  

Here is the power produce by the solar panel when at Saturn's orbit

=>        

So

=>    

=>    

explanation:

newton's third law, for every action there is an equal and opposite reaction.
