The strength of the gravitational forces between two masses depends on
-- the product of the masses,
-- the distance between their centers of mass.
Answer:
D
Explanation:
ionic compounds conduct electricity when molten or dissolved in water. ionic compounds conduct electricity when dissolved in water because water molecules are attracted to ions, this weakens the strong electrostatic forces of attraction between the oppositely charged ions. thus, ions are pulled away from the lattice structure and the remaining compound dissolves in water to form aqueous solution. The presence of free moving ions enables the ionic compound to conduct electricity.

He's accelerating at 3 m/s² .
That means his speed is increasing by 3 m/s every second.
At the end of 8 seconds, his speed is (8 x 3 m/s) = 24 m/s .
He's been moving south for the whole 8 seconds.
So at the end of that time, his velocity is
24 m/s south .
An example of a statement that best sums up evolution is: change in a population through genetic variation over time. Hope this helps!
Answer:
<h2><u>
sun generates energy from a process called nuclear fusion.</u></h2>
Explanation:
<u>During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released</u>
