Answer:
Explanation below:
Explanation:
Annual motion describes the changes in motion of the earth around the sun. Diurnal motion can be better understood as the change in motion caused by Earths rotation at the poles.
This might not be the answer you were looking for, your question is very vague.
Answer:
c) curves downward, below the initial velocity vector
Explanation:
A projectile is usually launched from a height, where it is launched with an initial velocity. From that point the gravitational force begins to act on the projectile causing it to decay. As time passes, the projectile advances but its height decreases. So its trajectory is curved downward, below the initial velocity vector.
Answer:
When we double the angular velocity the maximum acceleration 
will changes by a factor of 4.
Explanation:
Given the angular frequency 
of the simple harmonic oscillator is doubled.
We need to find the change in the maximum acceleration of the oscillator.
Now, according to the problem, the angular frequency got doubled.
Let us plug 
. Then the maximum acceleration will be 
We can see, when we double the angular velocity the maximum acceleration will changes by a factor of 4.
