Answer:
E - Lift-off for the return trip from Phobos requires much less fuel than that from Mars because of Phobos weaker gravitational pull.
Explanation:
Fuel requirement might be lesser in case of Phobos expedition.
This explains the fact that fuel consumption during lift off from Phobos is greater than the fuel consumption during lift off from Mars. Therefore E is the best answer.
Answer:
0.21 lunar month
Explanation:
the radius of moon = r₁
time period of the moon = T₁ = 1 lunar month
The radius of the satellite = 0.35 r₁
Time period of satellite
The relation between time period and radius
now,
T₂ = 0.21 lunar month
hence, the time period of revolution of satellite is equal to 0.21 lunar month
