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:
D disruption of hibernation or migration cycles
Answer:
The ozone layer acts as a shield for life on Earth. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms' protective layers, like skin, damaging DNA molecules in plants and animals.
