Hunter wants to measure the weight of a dumbbell. He should use a scale and record the weight in N.

Option D

Explanation:

The weight of an object refers the gravity force it affects, and this can be indicated as the mass multiplied by the acceleration due to gravity force, w = mg. Because weight is the force and so the unit is Newton. When you are not on weight, the net force on the scale and on the ground is zero, and the scale value (and normal strength) corresponds to the weight of the system. When you stand on the scale and raise or lower the bar, the center of gravity of the system rises and falls much more than the weight compresses or expands.

Therefore, the scale power (power) must be increased or decreased (the ground is solid) so that the center of gravity can move, raise and lower. When the center of gravity begins to move at a constant speed, the scale force decreases, matching the weight of the system. If you start to slow down and stop the dumbbell movement, the balance will change the weight again until you stop it. Hence, option D would be the right choice.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
