In your neighborhood, people are setting up a downhill soapbox derby race. As a safety measure, bales of hay are set up at the bottom of the hill as a barricade to stop cars and drivers. At what point on the car’s path will it have the most kinetic energy? A) at the very top of the hill B) at the midpoint of the hill C) at the very bottom of the hill D) after it collided with the hay

  The answer is C) at the very bottom of the hill because the top of a slope has the most potential energy and as it goes down it is converted to kinetic energy, so at the very bottom there is more kinetic energy.

Explanation:

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
