It doesn't. We do.
We rotate in such a way that the sun looks like it is rising and falling, but it really isn't.
Answer:
The answer is <u>C) at the very bottom of the hill</u> because the top of a slope has the most potential energy and as it goes down it is converted to kinetic energy, so at the very bottom there is more kinetic energy.
Explanation:
An increase in the distance between the objects causes a greater change in the gravitational force than the same increase in mass.
This is because the relationship between force and distance for a gravitational force is F ∞ 1/r²
(I couldn't find a proportional sign so I used ∞ instead)
Answer:
Yes.
Explanation:
Sound waves travel through metal 17 times faster than air.
Answer:
see that the correct one is D
Explanation:
In this problem the satellite is subjected to the universal force of attraction
F = G M m / r²
using Newton's second law with centripetal acceleration you can find the angular velocity of the satellite
F = m a
F = m w² r
G M / r³ = w²
and w = 2π / T
In this case, the satellite is in a two-dimensional movement, where the free fall of the satellite is compensated by the horizontal displacement, for which it is always at a distance from the earth, remaining at the same point.
When reviewing the different statements we see that the correct one isD
