A satellite is in orbit 3.117106 m from the center of Earth. The mass of Earth is 5.9821024 kg. Calculate the orbital period of the satellite.

T = 1733.16 s = 28.88 min

Explanation:

The orbital velocity of a satellite about Earth is given as follows:

where,

v = orbital speed = ?

G = Gravitational Constant = 6.67 x 10⁻¹¹ Nm²/kg²

M = Mass of Earth = 5.982 x 10²⁴ kg

R = Orbit Radius = 3.117 x 10⁶ m

Therefore,

but the velocity is given as:

for distance = circumference = 2πR

time = time period = T = ?

Therefore,

T = 1733.16 s = 28.88 min

answer; /// the above statement is (true);

d) physical means can be used to separate the components of air.
