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:
Aerosol effects
Explanation:
Aerosol effects
Aerosol is a small packets of air that remain in the atmosphere.
We know that the sun is the major source of energy on the earth but it is not true that we receive all that energy. some portion of that energy is either absorbed by aerosol or clouds . therefore it keep the temperature of earth little cool. However some aerosol also reflect the sun energy and this depends on solely on the composition of particle that make aerosol.
Answer:
Solar flares are massive explosions of energy in the Sun's atmosphere.
The new technique allows changes in the Sun's magnetic fields, which drive the initiation of solar flares, to be monitored up to ten times faster than previous methods.
