Answer: The changing magnetic field caused by the material's motion induces a current in the coil of wire proportional to the change in field. If a 0 is represented, the magnetic field does not change between the two domains of a bit, so no current is induced as the magnetic material passes the coil.
Answer:
option b is correct..................
Answer:
-10 m/s²
Explanion:
(0 m/s - 50 m/s) ÷ 5 seconds
You subtract the original speed from the final speed, (to get negative 50), then divide that by 5 seconds.
Hope this helps! :)
