Answer:
91.64 km
91.64 km high material would go on earth if it were ejected with the same speed as on Io.
Explanation:
According to Newton Law of gravitation:
Where:
G is gravitational constant=
For Moon lo g is:
According to law of conservation of energy
Initial Energy=Final Energy
For Jupiter's moon Io:
Velocity is given by:
For Earth Velocity is given by:
Now:
91.64 km high material would go on earth if it were ejected with the same speed as on Io.
To solve this problem we will use the mathematical definition of the light years in metric terms, from there, through the kinematic equations of motion we will find the distance traveled as a function of the speed in proportion to the elapsed time. Therefore we have to
means Light Year
Then
If we have that
Where,
v = Velocity
x = Displacement
t = Time
We have that
= Speed of light
Therefore will take 14.399 years

It is not B, or A, nor C.
Answer:
Gravity
Explanation:
Gravity is a force that pulls the surface of the earth and keeps the planets in orbits around the sun.
