The exact same amount of force will be exerted but in opposite direction
B is the correct answer . That make the most sense
Answer:
Velocity, quantity that designates how fast and in what direction a point is moving.
Explanation:
Answer: 0.107
Explanation:
We can solve this problem with Kepler's Third Law of Planetary motion:
(1)
Where:
is the orbital period of Phobos around Mars
is the Gravitational Constant
is the mass of Mars
is the semimajor axis of the orbit Phobos describes around Mars (assuming it is a circular orbit, the semimajor axis is equal to the radius of the orbit)
Well, firstly we have to convert the orbital period to seconds:
Now, we have to find
from (1):
(2)
(3)
(4) This is the mass of Mars
On the other hand, it is known the mass of the Earth is:
(5)
Then, if we want to know the ratio of Mars’s mass to the mass of the earth, we have to divide
by
:

Finally:
