| Answer» <p>Inertia is the measure of the mass of the body. The greater is the mass of the body;the greater is its inertia and vice-versa.(a) Mass of a stone is more than the mass of a rubber ball for the same size. Hence,inertia of the stone is greater than that of a rubber ball.(b) Mass of a train is more than the mass of a bicycle. Hence, inertia of the train isgreater than that of the bicycle.(c) Mass of a five rupee coin is more than that of a one-rupee coin. Hence, inertia ofthe five rupee coin is greater than that of the one-rupee coin.</p> | |
