Answer:
D: The side of Magnet A that's attracted to Magnet B's south pole must be Magnet A's north pole
Explanation:
D: The side of Magnet A that's attracted to Magnet B's south pole must be Magnet A's north pole because
1) opposite poles attract each other
2) similar poles repel each other
3)magnetic lines of force start at the north pole and end at the south pole
Speed is the secular unit, which means it only measures "how fast it goes."

Velocity is a victory unit, which means it measures "both how fast it goes AND the direction."

Acceleration is the change of velocity over time.
Answer:

Explanation:
As we know that the length of the conductor is given as

now if it is converted into a square then we have


now the are of the loop will be

now the magnetic flux is defined as

here we know
B = 1.0 T



Through vibration when it vibrates
it transfer momentum.
