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.

The quantity of charge Q in coulombs (C) that has passed through a point in a wire up to time t (measured in seconds) is given by :
We need to find the current flowing. We know that the rate of change of electric charge is called electric current. It is given by :
At t = 1 s,
Current,
So, the current at t = 1 s is 3 A.
For lowest current,
Hence, this is the required solution.
