Answer:
F
Explanation:
Newton's Third Law (Law of Action-Reaction) states:
Every action has an equal and opposite reaction and it occurs between two objects
In this scenario, the action would be the skater pushing off of the wall, therefore the reaction would be the wall pushing off of the skater since the two objects that are interacting are the wall and the skater.

Hope it helps!
Answer:

Explanation:
For answer this we will use the paralell axis theorem:
I= 
Where
is the moment of inertia of the center of mass, M is the mass of the sphere and d is the distance between the center of mass and the axis for rotate, then:


Answer:
3,200,000,000 J
Explanation:
Work is defined as the amount of energy transferred as an object is moved a certain distance with a certain force. Mathematically, we express this with the equation

where W is work (measured in joules), F is the force applied (in Newtons), and s is the distance, also called the <em>displacement </em>(in meters).
Here, we have F = 1,600,000 N and s = 2000 m, so our work will be
J
They will become identical as if they were never broken
