Step 1: Write down the information you already know

rE= 6.38x106 m

mE= 5.98x1024 kg

G= 6.67x10-11 N*m2 /kg2

Step 2: Determine the distance between the satellite and the Earth's centre

r=rE+1.00x106 m

r=6.38x106+1.00x106

r= 7.38x106 m

Step 3: Use the following formula to solve for the velocity of the satellite

v= square root of (Gme/r)

v= square root of ((6.67x10-11)(5.98x1024)/7.38x106)

v= 7.35x103 m/s

Where is a satellite when it stays at the same point above earths surface?

A satellite is considered to be in geostationary orbit when it stays in a fixed position above a specific point on Earth's surface. It orbits at the same rate as the Earth's rotation, which allows it to remain stationary relative to the ground below. Geostationary satellites are commonly used for communication and weather monitoring purposes.


Why is it important that a satellite be above Earths atmosphere?

Please remember that close to Earth's surface, a satellite must move at a speed of about 7900 meters/second. If it is inside the Earth's atmosphere, the force of friction will make the satellite lose energy. As a result, it will soon crash to the Earth's surface.


What causes surface ocean currents to flow in a circular pattern or earths revolution earths revolutoin or earths rotation?

Surface ocean currents flow in a circular pattern due to a combination of Earth's rotation (Coriolis effect) and the shape of the continents. The Coriolis effect causes water to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, resulting in the circular motion of currents. This, along with the shape of the coastlines, influences the direction and pattern of ocean currents.


Velocity parallel to earths surface?

The velocity parallel to Earth's surface can vary depending on the location and purpose. For a person walking or running on Earth's surface, the velocity can range from 0 m/s to a few meters per second. However, for objects in Earth's orbit, the velocity parallel to the surface can be much higher, reaching several kilometers per second.
