The orbital speed of Earth about the Sun is 3.00 × 104 m/s and its distance from the Sun is 1.50 × 1011 m. The mass of Earth is approximately 6.00 × 1024 kg and that of the Sun is 2.00 × 1030 kg. What is the magnitude of the force exerted by the Sun on Earth?

The force exerted by the Sun on Earth is .

Explanation:

The universal law of gravity is defined as:

 (1)

Where F is the force, m1 is the mass of the Earth and m2 is the mass of the Sun, G is the gravitational constant and r is the distance between them.

Then, equation 1 can be used to determine the force exerted by the Sun on Earth.

Hence, the force exerted by the Sun on Earth is .

a) cold, dry

explanation:

continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. as they move into warmer air, they can trigger precipitation.
