Answer:

Explanation:
The relative velocity can be calculated by means of the difference between vector B minus vector A.

Explanation:
Right hand thumb rule : Point the thumb of your right hand in the direction of the current flow, the direction of curvature of the fingers will give us the direction of the magnetic field produced by current carrying wire. This rule was given by Maxwell.
1) If the current is moving in upward direction , the direction of the magnetic field will be in anti clock wise direction.
2) If the current is moving in downward direction , the direction of the magnetic field will be in clock wise direction.
Answer:
6.32 m/s 18.43° northeast
Explanation:
We express the velocity of hawk as:

We consider positive x towards east and positive y due north. So the magnitude is simply the square root of the square components:
≈
And the angle with respect to the east should be with:
