We are asked to know the reason why magnetic dipole can be written as U = -m *B. The reason for this was that the negative sign is just showing or indicating the direction of the force. If it if negative, it means that the work done is opposite to the force field.
The order goes like this:
Radio, Micro waves, Infrared, Visible, UV (Ultra Violet), X-Ray, Gamma Ray.
A prediction is a guess of something happening in the future.
Answer:
<h3>The answer is option B</h3>
Explanation:
The wavelength of a wave can be found by using the formula
where
c is the speed of the wave
f is the frequency
From the question
c = 343 m/s
f = 466 Hz
We have
We have the final answer as
<h3>0.74 m</h3>
Hope this helps you
The force (attractive if the charges are dissimilar, else repulsive) is along a line that connects the two particles.
