Which of the following has the greatest inertia?a)A single atomb)a mol...
Inertia is the resistance of an object to changes in its state of motion. It depends on the mass of the object. Generally, objects with greater mass have greater inertia.
Comparing the given options:
a) A single atom: Atoms are extremely small and have very low mass compared to other objects. Therefore, a single atom has the lowest inertia among the given options.
b) A molecule: Molecules consist of multiple atoms bonded together. The mass of a molecule depends on the types and number of atoms it contains. It can vary significantly, but generally, molecules have more mass than a single atom. Therefore, a molecule has greater inertia compared to a single atom.
c) A one-rupee coin: A one-rupee coin typically has a mass greater than that of a molecule. It is composed of metal and has a significant size compared to atoms or molecules. Thus, a one-rupee coin has greater inertia than both a single atom and a molecule.
d) A cricket ball: A cricket ball is much larger and heavier than a one-rupee coin. It has a mass greater than all the previous options. Consequently, a cricket ball has the greatest inertia among the given options.
Therefore, the cricket ball (option d) has the greatest inertia.
