The correct answer is
A. The mechanical energy transforms to thermal energy as the pendulum slows and eventually stops moving.
In fact, we must keep in mind the presence of the air, which causes some resistance to the motion of the pendulum. As the pendulum moves through the air, part of its mechanical energy is transferred to the molecules of air because of the friction of this molecules with the surface of the pendulum. As a result, the pendulum slows down, and eventually stops. The initial energy of the pendulum has been converted into thermal energy of the molecules of air, which move faster now.
Answer:
a = w² r
Explanation:
In this exercise, indicate that the wheel has angular velocity w, the worm experiences the same angular velocity if it does not move, and has an acceleration towards the center of the circle, according to Newton's second law, called the centripetal acceleration.
a = v² / r
angular and linear variables are related
v = w r
we substitute
a = w² r
where r is the radius of the wheel

a 50-mL beaker with the same label.
hope it helps
Okay my dude...
It is best to end up your relationship with Heaven.
You can already know from the description you put to her compared to Kye.
So it is better to have someone who knows how to love you than someone that knows how to forget you.
And also, does Kye know that you have another lover? 0 - 0
It could rotate while not advancing distance
