Its Kinetic, hope this helps you
Answer:
The answer is b the radiation of the suns electromagnetic waves
Explanation:
I took the Quiz to.
<span>When an object is forced into resonance vibrations at one of its natural frequencies, it vibrates in a manner such that a standing wave is formed within the object. ... such patterns are only created within the medium at specific frequencies of vibration.</span>
For this case we have that according to Newton's second law it is true that:

Where:
F: It is the force
m: It is the mass
a: It is the acceleration
According to the data we have:

So, we have:

Thus, the applied force will be 7 Newtons.
Answer:

Static equilibrium.
Static equilibrium is a kind of equilibrium which occurs when an object is at rest.
Hope this helps!
