Answer:
The moons gravitational force at different points on the earth
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 .
Glaciers that form high up in the mountains are classified as alpine.
Answer: B. Alpine.
Cells are limited in size by their surface area and volume ratio which means that when cells get so large, there is a limit that they can no longer obtain enough oxygen and nutrients. This process is involved in cell growth.
