Explanation:
When a current-carrying wire is immersed in a region with magnetic field, the wire experiences a force, given by
where
I is the current in the wire
L is the length of the wire
B is the strength of the magnetic field
is the angle between the direction of I and B
In this problem we have:
L = 0.65 m is the length of the wire
I = 8.2 A is the current in the wire
F = 0.40 N is the force experienced by the wire
since the current is at right angle with the magnetic field
Solving the formula for B, we find the strength of the magnetic field:
Answer: Yes
Explanation:
Velocity is defined as the distance traveled
in a specific time
:
If you are traveling at a distance
, then the time it will take you to be at work is:
This means you will make it on time, because this time is less than 0.25 h.
