Answer:
please the answer below
Explanation:
A general electromagnetic plane wave, traveling in the x direction, can be expressed in the form:
(1)
1.
a. amplitudes
from (1) we can observe that E_0 and B_0 are the amplitudes.
2. frequency
3.
By replacing (1) we obtain:
![\vec{E}=E_0e^{-i(k(0)-\omega t)}\hat{j}=E_0[cos\omega t+sin\omega t]\hat{j}](https://tex.z-dn.net/?f=%5Cvec%7BE%7D%3DE_0e%5E%7B-i%28k%280%29-%5Comega%20t%29%7D%5Chat%7Bj%7D%3DE_0%5Bcos%5Comega%20t%2Bsin%5Comega%20t%5D%5Chat%7Bj%7D)
4.
the wave respond to the followinf physical variables: amplitude, frequency, time and position, as we can see in (1).
hope this helps!!
It’s D the time period within pendulums are constant, distance is always measured with kilometers within cities and basic unit is always seconds.
Are there choices that come with this question?
In up milling the cutter rotates clockwise when cutting the workpiece from right to left. in down milling the cutter rotates clockwise when cutting the workpiece from left to right
Answer:
0.625 c
Explanation:
Relative speed of a body may be defined as the speed of one body with respect to some other or the speed of one body in comparison to the speed of second body.
In the context,
The relative speed of body 2 with respect to body 1 can be expressed as :
Speed of rocket 1 with respect to rocket 2 :
Therefore, the speed of rocket 1 according to an observer on rocket 2 is 0.625 c
