Answer:
C. Your friend is incorrect, at this point, the cannon ball just has potential energy.
Explanation:
Potential energy is the kind of energy that an object has due to its position.
The unit for energy in the International System of Units (SI) is the joule, which has the symbol J.
Potential energy is usually related to forces that act on a body in a way that the total work done by these forces on the body depends only on the initial and final positions of the body in space.
These forces, receive the name of conservative forces and can be represented at every point in space by vectors expressed as gradients of a certain scalar function called potential.
I didn't actually understand the question but I will try to solve it.
Length of ribbon = 3 ft
Total number of small pieces = 8
So, length of each piece = 3/8 = 0.375 ft
Guidance means to lead and advise someone or teach them or to walk them through something, whether it be a place or idea. If a child needed help crossing the street, the parent would provide guidance and get them to the other side of the street by holding their hand and watching for cars. The child wouldn't be able to do it them self because they don't know how to watch for cars or when it is safe to go.
