The solute would then sink to the bottom and would not dissolve
Definitely D. The brakes on a bike rub against the wheel. Not sure about the others.
<h2>From kinetic theory of gases, the pressure exerted by a gas is given by velocity of gas molecules. m = Mass of each molecule of a gas. But by assumptions of the kinetic theory of gases the average kinetic energy of a molecule is constant at a constant temperature.</h2>
Answer:
Density=mass/volume 40 divided by 8 =5
