How do the Earth and Moon compare in terms of gravitational force?

Law Incorporation [45]

The Earth and Moon compare in terms of gravitational force as Earth's gravitational force is stronger than the Moon's.

Option A

<u>Explanation:</u>

According to universal law of gravity, the gravitational force is the attractive force between two objects separated by a distance. The magnitude of gravitational force is directly proportional to the product of masses of the objects and inversely proportional to the square of the distances between them.

In this case, the gravitational force acting on us due to Earth will be considered due to the mass of Earth as the mass of Earth is very large compared to our mass.

$F=\frac{GM}{R^{2} }$

So as the mass of the Earth is greater than the mass of the moon, so the gravitational force of Earth will be stronger than that of Moon.

Consider the cell cycle; which stage takes pretty much the same amount of time regardless of cell type? Explain

Natalija [7]

Answer:

The correct answer would be mitosis or M phase.

Mitosis or M phase is the phase of the cell cycle during which the actual division of the cell takes place that is, the division of nuclear content. It is also termed as karyokinesis.

It is primarily divided into four stages:

Prophase
Metaphase
Anaphase
Telophase.

It results in the equal distribution of chromosomes into two daughter cells.

It is followed by cytokinesis by which cytoplasmic content is equally divided into the two daughter cells.

wariber [46]

The word sponge is more appropriate to use than Underground river since an underground river can loose water while an aquifer cannot loose water, unless it is open-air and above ground. then the aquifer would slowly loose water due to evaporation from the sun.
