Answer:
Explanation:
Let the initial charge on the two spheres are
now we know that the force between them is given as
now when two spheres are connected then final charge on them is given as
now the force between them is given as
now we have
So by solving above two equations we have
Answer:
c. density decreases because the molecules move farther apart
Explanation:
As a liquid is heated, the molecules move faster and move farther apart. This causes the volume to increase, which causes the density to decrease.
