Water flows steadily through a pipe of length L and radius R=75mm. The velocity distribution across the outlet is given by u=uma
x 1− r2 R2 and umax =3m=s. Evaluate the ratio of the x-direction momentum flux at the pipe outlet to that at the inlet.

Answer:
The ratio of the orbital time periods of A and B is
Solution:
As per the question:
The orbit of the two satellites is circular
Also,
Orbital speed of A is 2 times the orbital speed of B
(1)
Now, we know that the orbital speed of a satellite for circular orbits is given by:
where
R = Radius of the orbit
Now,
For satellite A:
Using eqn (1):
(2)
For satellite B:
(3)
Now, comparing eqn (2) and eqn (3):
