What is the density of a billiard ball that has a volume of 100 cm3 and a mass of 250 g?

Explanation:

The density of a substance can be found by using the formula

From the question

mass = 250 g

volume = 100 cm³

So we have

We have the final answer as

Hope this helps you

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
