Which ball has larger Inertia before touching the ground when it falls freely from a certain height (air friction is zero)
a. mass 50 kg b. mass 25 kg
c. mass 10 kg d. All of these

Explanation:

Which has the larger inertia

Inertia (I) is calculated as follows:

Where m represents the mass of the object and r represents the distance from the axis.

Take for instance m = 10 and r = 4

The inertia would be:

Assume r is constant and m is increased to 25

The inertia becomes:

Notice that there is an increment in inertia, when the mass increased.

Hence, mass of 50kg will have the larger inertia.

multiply 2kg by latent heat of vap

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
