Answer:
Part a)
Part b)
Explanation:
As the uniform sphere is rolling down the inclined plane then the net force on the sphere is given as
also we have torque equation on it
for pure rolling
now we have
now we have
now given that
so we have
Part b)
If the inclined plane is frictionless then the acceleration is given as
<span>A free body diagram is a representation of how the forces that are acting on a point or particle interact. You place your point at the origin and then draw your forces.

Answer:
I belive it would be ture
Explanation:
It's been a while since I learned this but I think that is right.
Answer:
Mg- 27 means isotope with 12 protons and 15 neutrons.
Also 27 is mass number which express sum of protons and neutrons.
In nucleus one neutrn decays to electron and proton. Mass number remain same but Al-27 nucleus contain 13 protons and 14 neutrons. Electron is ejected out from nucleus.
From the word compound, the compound machine is already a combination of two or more types of simple machine. Thus, the answer is letter C. Because of its complexity, it is able to perform several other functions than a simple one.
