<h2>a- neither ball has a charge</h2>
Explanation:
The mass of the iceberg is 71.9 kg
Explanation:
The amount of thermal energy needed to completely melt a substance at its melting point is given by

where
is the latent heat of fusion
m is the mass of the substance
In this problem, we have a block of ice at its melting point (zero degrees). The amount of heat given to the block is

And the latent heat of fusion of ice is

So, we can re-arrange the equation to find m, the amount of ice that will melt:
