Answer:
transverse wave: A wave in which particles of the medium move at right angles to the direction of the wave is called a transverse wave.
This is not really a physics question but I can still help. It’s easier if you make a table. I hope this helped.
Correct answer choice is :
A) From A to B is known as the wavelength and changing the pitch of the note will change its length.
Explanation:
The amount or quantity of period within two things, points, lines, etc. the state or fact of existing separate in space, as of one thing from another; remoteness. a linear amount of space: Seven miles is a distance too great to walk in an hour. Distance is a scalar quantity describing the interval in two points. It is just the measure of the interval.

"<span>A small glass bead has been charged to + 25 nC "
Solution
The force exerted on a charge q by an electric field E is given by
</span>

<span>Considering the charge on the bead as a single point charge, the electric field generated by it is
</span>

with

,

is the charge on the bead. We want to calculate the field at

:

The proton has a charge of

, therefore the force exerted on it is

And finally, we can use Newton's second law to calculate the acceleration of the proton. Given the proton mass,

, we have


The charge on the bead is positive, and the proton charge is positive as well, therefore the proton is pushed away from the bead, so:
