Answer:
escavation
Explanation:
During excavation, archaeologists often use stratigraphic excavation to remove phases of the site one layer at a time. This keeps the timeline of the material remains consistent with one another.
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
Rivers typically come from underwater springs. They can also form from mountains and hills from melted snow.
Although the original purpose of construction for the Great Pyramid of Giza is not known, the widely accepted opinion is that the pyramid is believed to be the tomb of King Khufu. (I hope this helps.)
