Question

Gravitational force between the earth and the sun: a) it takes 365 days for the earth to complete one revolution around the sun. Find three different ways to change the number of days it takes for the earth to complete one revolution around the sun?

Answer 1

The number of days it takes for the Earth to complete one revolution around the Sun can be changed by altering the orbital speed, the distance between the Earth and the Sun, or the mass of the Sun.

Step-by-step explanation:

The number of days it takes for the Earth to complete one revolution around the Sun can be changed in several ways.

1. Changing the orbital speed: If the Earth's orbital speed around the Sun is increased, it would complete the revolution in fewer days. Similarly, if the orbital speed is decreased, it would take more days to complete the revolution.
2. Increasing the distance: If the distance between the Earth and the Sun is increased, it would take more days for the Earth to complete its revolution. Decreasing the distance would result in a shorter revolution period.
3. Changing the mass of the Sun: The gravitational force between the Earth and the Sun depends on the mass of the Sun. If the mass of the Sun is increased, the Earth would experience a stronger gravitational force, resulting in a shorter revolution period. Conversely, if the mass of the Sun is decreased, the revolution period would be longer.
