An artificial sattelite is moving in a circular orbit of radius 42250km calculate its speed if it takes 24 hours to revolve arou
1 answer:
Answer:
v = 11061.02 km/h
Explanation:
Given that,
The radius of the circular orbit, r = 42250 km
Time taken to revolve around the Earth, t = 24 hours
We need to find the speed of the satellite. We know that, speed of an object is equal to total distance traveled divided by the time taken. So,
Put all the values,
So, the speed of the satellite is equal to 11061.02 km/h.

<h2>The magnitude 24 (
) of the acceleration of the particle when the particle is not moving.</h2>
Explanation:
Given,
A particle moving along the x-axis has a position given by
m ........ (1)
To find, the magnitude ( ) of the acceleration of the particle when the particle is not moving = ?
Differentiating equation (1) w.r.t, 't', we get
⇒ ....... (2)
⇒
⇒
⇒ t = 2 s
Again, differentiating equation (2) w.r.t, 't', we get
Put t = 2, we get
Thus, the magnitude 24 ( ) of the acceleration of the particle when the particle is not moving.
