(a) The speed of a satellite on a low lying circular orbit around this planet is 7,338.93 m/s.
(b) The minimum speed required for a satellite in order to break free permanently from the planet is 10,378.82 m/s.
(c) The radius of the synchronous orbit of a satellite is 69,801 km .
<h3>Speed of the satellite</h3>
v = √GM/r
where;
- M is mass of the planet
- r is radius of the planet
v = √[(6.67 x 10⁻¹¹ x 4.74 x 10²⁴) / (5870 x 10³)]
v = 7,338.93 m/s
<h3>Escape velocity of the satellite</h3>
v = √2GM/r
v = √[( 2 x 6.67 x 10⁻¹¹ x 4.74 x 10²⁴) / (5870 x 10³)]
v = 10,378.82 m/s
<h3>Speed of the satellite at the given period </h3>
v = 2πr/T
r = vT/2π
r = (7,338.93 x 16.6 x 3600 s) / (2π)
r = 69,801 km
Thus, the speed of a satellite on a low lying circular orbit around this planet is 7,338.93 m/s.
The minimum speed required for a satellite in order to break free permanently from the planet is 10,378.82 m/s.
The radius of the synchronous orbit of a satellite is 69,801 km .

Answer:
B. The force of motion is different when a strong or a weak force is applied to the ball.
Explanation:
If you kick the ball the with stronger force, the ball will travel further than it would if weaker force were to be applied to the ball. In other words, if you softly kicked a ball, it wouldn't go as far as it would if you kicked the ball hard/with more force.
Coffee will trigger it i think tell if correct
Answer:
A
Explanation:
According to Snell's law refractive index is the ratio of the sine of the angle of incidence to the normal to the barrier ( the normal is perpendicular to the surface of the barrier) to the ratio of the sine of refraction ( the angle of emergence from the second barrier) and also equals the ratio of the speed of light in the first barrier to the ratio of the speed of light in the second barrier.
Since there is no change in the direction of the propagation of light then the two materials must have matching indexes of refraction.
The distance between the drone and the car will be 20,3 m/s.
<h3>What is average velocity?</h3>
In physics, velocity is a quantity that identifies the displacement of a body in a given time. Thus, the average velocity measures in an average time interval, the speed of displacement of a body.
With that being said, Suppose that both car and drone starts from 0 and move towards north and east, respectively. So, after T time:
Distance covered by the car,
Distance cover by the drone,
Considering the elevations of 25m, the actual distance between them at any T instant:
Speed,
So, the distance between the drone and the car will be 20,3 m/s.
