Answer:
If you apply a force to separate 2 opposite poles, the potential energy of the system increases.
Magnitude of acceleration
Explanation:
We know that acceleration can increase depending in the force applied on an object, any object with a greater mass will apply a greater force. F = M(a).
Answer:
Explanation:
Given
time taken 
Speed acquired in 2 sec 
Here initial velocity is zero 
acceleration is the rate of change of velocity in a given time


Distance travel in this time

where
s=displacement
u=initial velocity
a=acceleration
t=time


so Jet Plane travels a distance of 42 m in 2 s
<span>v is perpendicular to both E and B and has a magnitude E/B</span>
It will be traveling exactly 24 miles per hour <span />
