The kinetic energy would be 53,775J:)
Answer:
Explanation:
The missing image of the figure slide is attached in below.
However, from the model, it is obvious that it is in equilibrium.
As a result, the relation of the force and the torque is said to be zero.
i.e.
and
From the image, expressing the forces through the y-axis, we have:
Also, let the force be the pivot and computing the torque to determine :
Then:
For the force equation:
where:
Then:
<h3><u>Answer;</u></h3>
Electromagnetic waves
<h3><u>Explanation;</u></h3>
- <em><u>A wave is a transmission of a disturbance from one point to another. It involves movement of energy from the source to another.</u></em>
- <em><u>Waves may be classified as mechanical waves or electromagnetic waves depending on whether they require material medium for transmission.</u></em>
- <em><u>Electromagnetic waves are those waves that do not necessarily require a material medium for transmission, that is they can be transmitted even in a vacuum. Such waves include, x-rays, radiowaves, microwaves, etc.</u></em>
- Mechanical waves on the other hand require a material medium for transmission. Such waves include sound waves.
using energy conservation equation,
a) 0.5*kx^2 = 0.5 mv^2
0.5 * K * (0.150)^2 = 0.5 *
0.0500 * 20^2
0.01125K = 10
K = 888.8889 N/m
b)
force = kx = 888.8889 * 0.150
= 133.3333 N
