Question

What do the three black arrows represent? A) The tidal force Earth exerts on the moon

B) the direction in which Earth's water is flowing
C) the Moon's gravitational force at different points on Earth
D) Earth's orbital motion

Answer 1

The three black arrows represent the Moon's gravitational force at different points on Earth, which causes the ocean tides by creating tidal bulges due to differential gravitational forces.

Step-by-step explanation:

The three black arrows most likely represent C) the Moon's gravitational force at different points on Earth. This is supported by the explanation that the Moon's gravity causes ocean tides on Earth, by exerting differential gravitational forces on different parts of the Earth's surface. The side of Earth nearest to the Moon experiences a stronger gravitational pull than the center, which in turn is pulled more strongly than the side opposite the Moon. These differences are what create the tidal bulges observed in the oceans, leading to high tides. Moreover, the tidal force can be viewed as the difference between the force at the center of Earth and that at any other location, thus creating two tidal bulges on the Earth as it faces both toward and away from the Moon.

Answer 2

The moons gravitational force at different points on the earth

Step-by-step explanation:

The perstubation force of the sun on the moon at two places in its orbit . The blue arrows represent the direction and magnitude of the gravitational force on the Earth. Applying this to both the Earth's and the Moon's position does not disturb the positions relative to each other. When it is subtracted from the force on the Moon (black arrows), what is left is the perturbing force (red arrows) on the Moon relative to the Earth. Because the perturbing force is different in direction and magnitude on opposite sides of the orbit, it produces a change in the shape of the orbit.

In astronomy , perturbation is the complex motion of a massive body subject to forces other than the

gravitational attraction of a single other

massive body .
