Consider the video tutorial you just watched. suppose that we repeat the experiment, but this time we replace the original 56-g magnet with a more powerful magnet of the same mass. as you know from experience, the more powerful a magnet is, the more strongly it attracts or repels other magnets or magnetic objects. you have also probably noticed that magnetic forces fall off sharply with distance—two magnets that interact strongly across a distance of millimeters interact more weakly at a distance of a centimeter. (in fact, the strength of the force falls off with the square of the distance.) compared to the magnet in the video, the magnet in part a will hover at a position compared to the magnet in the video, the magnet in part a will hover at a position 1- farther above the base. 2- at the same distance above the base. 3- closer to the base.

Fm - W = 0    1) true. Imams must separate, to match the two forces, you reach equilibrium

Explanation:

When the magnet is exchanged for a stronger one, but of the same weight, the equilibrium equation

         Fm - W = 0

         Fm = W

If the weight of the imam is the same, the magnetite force must decrease, so that it will occupy the magnets must be separated a greater distance, according to the formula

          Fm = Km m ’m / r²

Where Km is value 10⁻⁷ N s²/C², r is the distance between the poles

Let's review the proposed results

1) true. Imams must separate, to match the two forces, you reach equilibrium

2) False. In this case the weight would be less than the magnetic force

3) False The magnetic force increases and equilibrium is not reached

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
