Answer:
-2π ≤ ∅ ≤ 3π/2
0 ≤ ∅ ≤ π/2
Explanation:
In simple harmonic motion, the displacement and velocity vectors are as follows:
where ∅ is the phase angle. At t = 0, the initial displacement and velocity are
According to two equations, we need to find the ∅ values which makes both cosine and sine terms positive.
So, ∅ is in the range: [-2π, -3π/2] and [0,π/2]
Answer:
Option C.
The gravitational force between two objects is proportional to the product of their mass and inversely proportional to the distance between the two masses.
The formula of the gravitational force between two objects of mass
and
that are separated by a distance r is:
Where G is the gravitation constant.
You can see that as the masses increase, it also increases the gravitational force. But as the distance between the masses increases, the gravitational force decreases.
Therefore the correct option is the C "mass increases or distance decreases"
