I just googled refraction vs reflection. Hope this helps! :)
Answer: 3071.79 m/s
Explanation:
Approaching satellite's orbit around the Earth to a circular orbit, we can use the equation of velocity in the case of uniform circular motion:
(1)
Where:
is the velocity of the satellite
is the Gravitational Constant
is the mass of the Earth
is the radius of the orbit
Now, if we want the satellite to move in a <u>geosynchronous orbit</u>, it needs to travel at a specific orbiting radius and period to fulfill this condition. This means the satellite's orbital period must match Earth's rotation on its axis, which takes one sidereal day ( approximately 24 h).
So, if the satellite travels one complete circle in a period , its velocity is also expressed as:
(2)
Where
Combining (1) and (2):
(3)
Isolating :
(4)
(5)
Substituting (5) in (1):
(6)
Finally:
Answer:
3
Explanation:
Because the pressure in the air, it’s causes particles to move farther apart from each other.
