"a 2.0-m straight wire carrying a current of 0.60 a is oriented parallel to a uniform magnetic field of 0.50 t. what is the magn
1 answer:
The magnitude of the magnetic force acting on the wire is zero, because the magnetic field is parallel to the wire.
In fact, the magnetic force exerted by the magnetic field on the wire is
where I is the current in the wire, L the length of the wire, B the magnetic field intensity and
the angle between the direction of B and the wire. In our problem, B and the wire are parallel, so the angle is 
and so 
, therefore the magnetic force is zero: F=0.
In fact, the magnetic force exerted by the magnetic field on the wire is

Answer:
The box displacement after 6 seconds is 66 meters.
Explanation:
Let suppose that velocity given in statement represents the initial velocity of the box and, likewise, the box accelerates at constant rate. Then, the displacement of the object (), in meters, can be determined by the following expression:
(1)
Where:
- Initial velocity, in meters per second.
- Time, in seconds.
- Acceleration, in meters per square second.
If we know that ,
and
, then the box displacement after 6 seconds is:
The box displacement after 6 seconds is 66 meters.
