What is the time period of revolution of a satellite around Venus if its specific angular momentum is 18,919 mi2/s. The orbit of the satellite is circular. Gravitational parameter of Venus is 77,937.75 mi3/s.

What is the time period of revolution of a satellite around Venus if its specific angular momentum is 18,919 mi2/s. The orbit of the satellite is circular. Gravitational parameter of Venus is 77,937.75 mi3/s. Correct Answer 1.946 hours

Given, Specific angular momentum (h) = 18,919 mi2/s = 18,919 x 1.609342 km2/s = 49,000 km2/s Gravitational parameter (μ) = 77,937.75 mi3/s = 77,937.75 x 1.609343 km3/s = 324,856 km3/s Satellite radius (r) = h2/μ = 49,0002/324,856 = 7,390.967 km Time period (T) = 2πr3/2μ-1/2 = 2π*7,390.9673/2*324,856-1/2 = 7,004.65 s = 1.9457 hours

S1:The path of Venus lies inside the path of the Earth.
P :When at its farthest from the Earth, Venus is 160 million away
Q :With such a wide range between its greatest and leat distances it is natural that at sometimes Venus appears much brighter than at others.
R :No other body ever comes so near the Earth, with the exception of the Moon and occasional comet or asteroid.
S :When Venus is at its nearest to the earth it is only 26 million miles away.
S6:When at its brightest, it is easily seen with the naked eye in broad daylight.

The Proper sequence should be:
S1: The path of Venus lies inside the path of the Earth.
P: When at its farthest from the Earth, Venus is 160 million miles away.
Q: With such a wide range between its greatest and least distances it is natural that at sometimes Venus appears much brighter than others.
R: No other body ever comes so near the Earth, with the exception of the Moon and an occasional comet or asteroid.
S: When Venus is at its nearest to the Earth, it is only 26 million miles away.
S6: When at its brightest, it is easily seen with the naked aye in broad daylight.
