A)
The weight of a 0.60 kg object at the surface of Planet V is 20 N. The radius of the planet is 4 x 10 6 m. Find the gravitational acceleration at a distance of 2 x 10 6 m from the surface of this planet.
8.9 m/s2
11 m/s2
13 m/s2
18 m/s2
B)
Two masses are precisely 1 m apart from each other. The gravitational force each exerts on the other is exactly 1 N. If the masses are identical, what is each mass?
1.22 x 105 kg
1.34 x 1010 kg
2.50 x 105 kg
1.58 x 1010 kg
the question was: If Altair rises at 2 a.m. tonight how long before it will rise at midnight? but the answer provided by the expert was wrong because:
That is not true because a star rises or sets 4 minutes earlier each night which means that we have to get back in time 2 hours and it rises or sets 4 min inb 24 hours which will mnake 30 days. is that correct?
