Explanation:
F=(Gmm)/(r^2)
larger the mass stronger the force. An object with a large mass will produce a large force. A small mass will produce a small force.
<span>The kinetic energy of gas molecules is directly proportional to the Kelvin temperature of the gas</span>
Speed decreases more the denser the medium.
Since density of a material normally decreases with temperature, it is not surprising that the speed of light in a liquid will normally increase as the temperature increases. (Thus, the index of refraction normally decreases)
