Answer: you want your input force harder
Explanation:
I'm not sure what the alien Theory says or if there really is such a theory. If the theory says that aliens definitely exist and that they have visited Earth in the past then the theory is totally and completely without any kind of support. It's not scientific in any way because there is no evidence for such a claim. It may be thought to be probable but no solid evidence has ever been presented.
Answer:

Answer:
1.034 m above the floor
Explanation:
The location of center of body for a compound body, when the weights are given is calculated as:
where,
is the center of gravity of the entire body
W = weight of the individual body
x = center of gravity of the individual body
Thus on substituting the values we get,
or
or
Hence, <u>the center of gravity of the entire body lies </u><u>1.034 m</u><u> </u><u>above the floor</u>
Answer:
Explanation:
This problem is related to vertical motion, and the equation that models it is:
(1)
Where:
is the rock's final height
is the rock's initial height
is the rock's initial velocity
is the angle at which the rock was thrown (directly upwards)
is the time
is the acceleration due gravity in Planet X
Isolating and taking into account 
:
(2)
(3)
(4) This is the acceleration due gravity in Planet X
