Place the permanent magnet into an AC magnetic field and slowly reduce the field to 0 and the magnet will be temporarily demagnetized.
Light waves are never 'aborted'.
They can be 'absorbed', and I think that's what you mean.
It's what happens when light hits something or goes into it,
and never comes out.
"Absorb" just means "soak up". When a light wave hits something and
gets soaked up in it, it's gone, and never comes out the other side.
The light wave certainly gets changed ... it no longer exists.
The object that absorbs it also gets changed. It soaks up the energy
in the light wave, and it has a little more internal energy (heat) than it
had before the light hit it.
Answer:
I think the answer 1
Explanation:
im probably wrong too i dont know
The frequency of the 10th harmonic is 800 Hz
Explanation:
The frequency of the nth-harmonic for the standing waves in a string is given by the equation
where
is the fundamental frequency of the string
In this problem, we are given the frequency of the 3rd harmonic:
Which can be rewritten in terms of the fundamental frequency
So we find :
Now that we have the fundamental frequency, we can find the frequency of the 10th harmonic, with n = 10 :
