Answer:
B
Explanation:
just answered that question
Equation
KE. + PE. = KE<em>f </em>+ PE<em>f</em>
<em>By the time the Rocket reaches an infinete distance the </em><em>KE</em><em>f and </em><em>PE</em><em>f power would be down to zero so then the equation will become </em><em>KE. + PE. = 0 </em>
<em>Cant explain much because dont know if this anserw recwires any speical things to solve it</em>
Answer:
Explanation:
We are given that
Speed of light,v=
Diameter of ring,d=92 m
Radius,r=
Current, I=0.40 A
We have to find the number of electrons in the beam.
We know that
Current,I=
Where q= ne
Using the formula
The branch of science which deals with celestial objects, space, and the physical universe as a whole.
Online definition so if you’re using it for school work I recommend re-wording!
