Sound waves will either be reflected (echo effect) or absorbed (dissipated) depending upon the material make-up of the barrier
The answer is C. 15 meters North
Displacement is the distance and direction from the origin. If you move 20 meters North, your displacement is 20 meters North. If you move 5 meters South, you are basically moving back the way you came by 5 meters, which means you are now 15 meters North.
I hope this helped! :)
Answer:
The magnetic force will be 0.256 N in +y direction.
Explanation:
It is given that, a wire along the z axis carries a current of 6.4 A in the z direction. Length of the wire is 8 cm. It is placed in uniform magnetic field with magnitude 0.50 T in the x direction.
The magnetic force in terms of length of wire is given by :

For direction,

So, the magnetic force will be 0.256 N in +y direction.
