"a black hole forms when any object reaches a certain critical density, and its gravity causes it to collapse to an almost infinitely small pinpoint."
I know its not straight forward with the answer
Density<span> = Mass/Volume. The units for </span>density<span> are grams per cubic centimeter or grams per milliliter </span>
example force. because you can say" I applied 3 newtons downward to the floor".
force has magnitude and direcion
An "Electric Circuit" <span>is any path through which electrons can flow.
Hope this helps!</span>
