Answer:
The speed of the satellite is 25.57×10⁻⁵ m/s
Step-by-step explanation:
Satellite: These are bodies which move in orbit around the moon or planets. Some of them are are natural, others are artificial, i.e man-made.
The speed of a satellite in its orbit is represented by the expression below.
v = √(rg)................................. Equation 1
Where v = speed or velocity of the satellite, r = radius of the earth, g = acceleration due to gravity of the earth
Given: r = 6.67×10⁻¹¹ m
Constant: g = 9.8 m/s²
Substituting these values into equation 1,
v = √(9.8×6.67×10⁻¹¹ )
v = √(65.366×10⁻¹¹)
v = 25.57×10⁻⁵ m/s
Thus the speed of the satellite is 25.57×10⁻⁵ m/s
