Magnetic lines of forces make a closed loop because there are no magnetic charges (monopoles). While electric <span>field lines end on electric charges, magnetic field lines have no objects on which they could end. This is why they must form loops. </span>
Answer:
<h2>32m/s^2</h2>
Explanation:
We want to find the acceleration based on the given data
Given
distance s=400m
time t= 5s
u= 0m/s since it started from rest
We apply the following expression
s=ut+1/2at^2
substituting we have
400=0*5+1/2*a(5)^2
400=25a/2
cross multiply
25a=400*2
25a=800
divide both sides by 25 we have
a=800/25
a=32m/s^2
The acceleration is 32m/s^2
The answer is false
The type of current supplied is dc
It goes around the x axis
