Question

Jupiter is about five times as far from the Sun as Earth. Therefore, the strength of sunlight at Jupiter is about ________ as strong as it is at Earth.

Answer 1

Answer:

1/25 times

Explanation:

Given,

Jupiter is five times far from the sun.

We now,

Strength of sunlight is inversely proportional the square of the distance between the sun.

Intensity of sunlight on earth

   $I_1\ \ \alpha \ \dfrac{1}{r^2}$

Intensity of the sunlight on the Jupiter

    $intensity\ \ \alpha \ \dfrac{1}{(5r)^2}$

    $I_2\ \ \alpha \ \dfrac{1}{25}\ I_1$

Hence, we can say that intensity of sunlight is 1/25 times of intensity on earth.
