Answer: mass of moon = 7.350 * 10²² Kg

Mass of earth = 5.98 * 10²⁴Kg

Explanation:

acceleration due to gravity = (gravitational constant * mass of the body) / (distance from the centre of mass)²

g = Gm/r²

G = 6.673 * 10^-11

g(moon) = 1.62 m/s²

r (moon) = 1.74 *10⁶

g = GM/r²

M = gr² / G

M = 1.62 * (1.74 * 10⁶)² / 6.673 * 10^-11

M = 7.350 * 10²² Kg

Mass of moon = 7.350 * 10²² Kg

Mass of earth =?

g = GM / r²

M = gr² / G

g = 9.8 m/s²

G = 6.673 * 10 ^-11

r = 3.84 * 10⁸m

M = 9.8 * (3.84 * 10⁸)² / 6.673 * 10^-11

M = 5.98 * 10²⁴ Kg

Mass of the earth = 5.98 * 10²⁴kg

Why is an understanding of the structure of Earth important ​
NeX [460]

Answer:

Below

Explanation:

An understanding of the structure of the Earth is important for many reasons

1. It can help us understand things that happen on the surface, like the magnetic field. The structure of the Earth explains that.

2. Things like tectonic plates severely affect the planet, such as the creation of many natural disasters. Understanding them helps us better prepare and anticipate them.

3. Understanding the structure of the Earth can help us identify the location of important natural resources (like different metals)

4. In the production of things like geothermal energy we need to understand the Earth's structure to know where we will get the most heat
