Hello. You did not inform the experiment that Arthur is conducting, which makes it impossible for your question to be answered accurately. However, I will try to help you in the best possible way.
The hypothesis is an assumption that is made before the experiment is carried out. This hypothesis is formed with the observation of some phenomenon of nature where the researcher believes that two or more elements interact to form a result. In this case, the experiment is carried out to determine whether the assumption, that is, the hypothesis is false or true. In the event that an experiment determines that the hypothesis is false, two things may have occurred: (a) the experiment was set up, or analyzed incorrectly, (b) the elements tested have no relation to the observed phenomenon.
I think your question should be:
An industrial laser is used to burn a hole through a piece of metal. The average intensity of the light is
What is the rms value of (a) the electric field and
(b) the magnetic field in the electromagnetic wave emitted by the laser
Answer:
a)
b)
Explanation:
To find the RMS value of the electric field, let's use the formula:
Where
;
;
Therefore
b) to find the magnetic field in the electromagnetic wave emitted by the laser we use:
;
;
Velocity = Frequency x Wavelength
= 18 x 13 = 234 mm/s

(Direction) for the fact that it will continue having the momentum at the constant speed in which the engines turned off.
