The concept of 'Inertia' was first practically developed by which scientist before Newton incorporated it into his First Law? MCQ with Answer and Explanation

Explanation:
The height of capillary rise is given by Jurin's law: h = 2Tcos(theta) / (rrhog). In a freely falling elevator, the effective acceleration due to gravity (g') is zero (weightlessness). As effective g approaches zero, the theoretical height h approaches infinity. In reality, the water will rise to the very top of the tube, regardless of its length, but will not overflow.

Explanation:
Moderator slows fast neutrons to thermal energies to increase probability of fission. Common moderators: heavy water, graphite. Control rods (cadmium, boron) absorb neutrons. Coolant removes heat.

Explanation:
Newton's third law states that to every action, there is an equal and opposite reaction. Crucially, action and reaction forces always act on two different bodies. Because they act on different bodies, they do not cancel each other out, and each body experiences a net force based on the reaction it receives.
