A)Tides of the ocean are created mostly by the magnetic pull of the Moon. B)The amount of light viewers see on the Moon from the Earth changes each day. C)Other planets in our solar system also possess orbiting moons or satellites. D)The phase in between a New Moon and a Full Moon is called a First Quarter Moon. E)Some scientists theorize that the Moon was created from the Earth billions of years ago.

1.

B) The force exerted on Earth by the Sun is stronger than the corresponding force exerted by the Moon.

Explanation:

Gravitational force is proportional to the products of the masses of the bodies and inversely proportional to the square of their distance apart.

2.

A) The Moon exerts a stronger tidal force on Earth than the Sun does

Explanation:

the Moon produces a greater tidal force on the Earth than the Sun, even though the Sun exerts a greater gravitational attraction on the earth than that exerted b the moon on the earth.

The Sun's gravitational pull on the Earth is about 175 times stronger when compared to that exerted by the Moon but has a much smaller effect on the tides. This is due to the inverse square law. The Earth's diameter is a tiny fraction of the total distance between the Sun and Earth which means that the difference in gravitational force across the Earth varies by a very small amount. On the other hand, the Moon is much closer than the Sun, thus the difference in gravitational force from the Moon across the Earth is much greater. The Sun has approximately only 44% of tidal influence than that of the Moon.
