Energy
<h3><u>Explanation;</u></h3>
- A wave is a transmission of disturbance from one point to another. All waves involve transmission of energy from one point called the source to another point.
- <em><u>Waves describes various ways in which energy can be transferred from a point source.</u></em>
- <em><u>In electromagnetic waves</u></em><em>, for instance, </em><em><u>energy transmission occurs as a result of vibrations of electric and magnetic fields</u></em><u>.</u>
- <u><em>In mechanical waves energy transmission is as a result of vibration of particles in the medium used</em></u>. For example in sound waves, energy is transferred through vibration of particles of air or particles of a solid or medium through which sound travels through.
20N•m or 20J. Work is equal to force•distance, and 5N•4m is 20N•m, or J

You have to read this carefully enough that you don't mix up energy and forces.
Gravity is a force. If you don't believe me try jumping off a building. Which way are you going to go and why? Down because gravity attracts your mass.
So Magnetism must be a force as well. It acts in one direction, but not a specific one the way gravity acts). It also either attracts or repulses (pushes an object away)
Answer A
Answer:
the spring be displaced by 25.0 cm
Explanation:
The computation is shown below:
As we know that
F= -K × x
So,

Now

= -0.250m
= 25.0 cm
Hence, the spring be displaced by 25.0 cm
