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
Answer:
<em>Captain James Cook’s first exploration was to Tahiti to observe the transit of Venus in 1969.
</em>
Explanation:
James Cook was born in Yorkshire in 1728 to a farm labourer. He sailed for several years in the North Sea, Irish Sea, Baltic Sea. He volunteered many services with which he as appointed as an able seaman. He also worked as rank master, surveyor.
In 1969, he was promoted as a rank of Lieutenant and was instructed to sail to Tahiti to observe the transit of Venus in 1969. This expedition was to ascertain whether there is an existence in the Southern latitudes of the Pacific Ocean.

Answer:
1. Mining.
Mining affects the land by creating loss of biodiversity, sinkholes, mudslides and contamination. That’s just a few affects mining can have on the land.
2. Petroleum.
The main risk that happens when extracting petroleum are oil spills. Some of the worst oil spills in history have caused major fires, explosions, and contamination in the area where they are at. What’s worse is that innocent little animals get caught in those oil spills and die.
Hope this helps and pls mark me brainliest if it did :)
Explanation:
Coriolis force -
It helps to determine the turn of the wind to the right in the Northern Hemisphere due to the rotation of the Earth .
This effect does not impact the speed of the wind , it only affect the direction of the wind .
<u>The impact of the Coriolis force of the wind direction is as follows -</u>
From the north pole , the earth rotates at higher speed in the counter - clockwise direction , then the object will appear to deflect to the right of its intended path , due to the Earth's rotation .
