2.5m/s
Explanation:
Given parameters:
Initial velocity = 0m/s
Acceleration = 0.5m/s²
time of travel = 5s
Solution:
Final velocity = ?
Solution:
Acceleration can be defined as the change in velocity with time:
Acceleration =
From the equation above, the unknown is final velocity:
Final velocity - initial velocity = Acceleration x time
since initial velocity = 0
Final velocity = 0.5 x 5 = 2.5m/s

Answer:Increase by a factor of 25
Explanation:
We know that magnetic force is proportional to
where r is the distance between them
Thus
Where =magnetic field
If distance is reduced by a factor of then force must increase by a factor of
because
so
