Answer:
183.75641 Joules
Explanation:
F = Force of the vacuum cleaner = 84.5 N
s = Displacement of the vacuum cleaner = 2.62 m
= Angle the force makes with the horizontal = 33.9°
Work done is given by
The work done by the force of the vacuum cleaner is 183.75641 Joules
Land: Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills. Erosion by water and wind can wear down land and create landforms like valleys and canyons. ... Landforms can exist under water in the form of mountain ranges and basins under the sea.
Atmosphere: (4.6 billion years ago)
As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today's atmosphere. After about half a billion years, Earth's surface cooled and solidified enough for water to collect on it.
Ocean: After the Earth's surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries. As the water drained into the great hollows in the Earth's surface, the primeval ocean came into existence. The forces of gravity prevented the water from leaving the planet.
B is the correct answer . That make the most sense
Answer:
Distance between moon and earth = 
Explanation:
Distance traveled by radio waves = Velocity of radio waves * Time taken by radio waves
Velocity of radio waves = 
Time taken by radio waves = 1.28 seconds
So distance traveled by radio wave = 
Distance between moon and earth = 
=
