The relative brightness of the Sun as observed from Jupiter in comparison to its brightness from Earth.

Answer to Problem 9P
The relative brightness of the Sun as observed from Jupiter is
Explanation of Solution
Given:
Assume the distance between Jupiter and Earth is denoted by r .
The distance between Jupiter and Sun is denoted by 5. 2r .
Formula used:
The expression for the brightness of the solar
Here, P is the Sun’s output power and r is the distance of the planet from the Sun.
Calculation:
The brightness of the solar radiation on Earth is
The brightness of the solar radiation on Jupiter is,
Divide equation (2) by equation (1).
Conclusion:
Thus, the relative brightness of the Sun as observed from Jupiter is
