Speed (or Velocity) = Distance divided by time. So,
speed = 300/5.5
average speed = 54.54545455 or about 54.5 miles/hour
Answer:
Wrapping the bar with a coil of wire that has an electric current.
Explanation:
To cause an iron bar to start generating a magnetic field, wrap the bar with a coil that has an electric current.
- This process is known as making magnetics using an electric current.
- There is an interaction between electric and magnetic fields.
- Electrical current can be induced by magnetic fields and magnetism can be induced by electric currents.
Wrapping the bar with a coil of wire that has electric current can cause an iron bar to start producing magnetic fields. This way, the iron bar becomes a magnet.
The statement which is true about a polarized object would be "the number of the positive and negative charges can be the same." Polarized objects became polarized and it has its center of positive charges separated from negative charges.
