True it help support reglions
The potential energy of a body is the maximum at the highest position of that body. So for example, if the maximum position of the ball is at 3 m, there will be the maximum potential energy.
To get the half of the maximum potential energy, the ball should be at the half of the maximum position, which is 1.5 m.
Answer:
1. The tension in the rope is everywhere the same.
2. The magnitudes of the forces exerted on the two objects by the rope are the same.
3. The forces exerted on the two objects by the rope must be in opposite directions.
Explanation:
"Massless ropes" do not have a<em> "net force"</em> which means that it is able to transmit the force from one end of the rope to the other end, perfectly. It is known for its property of having a total force of zero. In order to attain this property, the magnitude of the forces exerted on the two stationary objects by the rope are the same and in opposite direction. <u>So this explains number 2 & 3 answers.</u>
Since the objects that are held by the rope are stationary, then this means that the tension in the rope is also stationary. This means that the tension in the rope everywhere is the same (provided that the rope is still or in a straight line, as stated in the situation above, and is being held by two points). <u>So, this explains number 1.</u>
Your answer is D- high energy and short wavelengths : )
Answer:
Explanation:
From the exercise we know:
So, the average acceleration is:
The average force is:
