Describe how a roller coaster works in terms of using potential energy and kinetic energy:

Traditionally, the coaster cars are pulled up the first hill by a chain; as the cars climb, they gain potential energy.  Then, when the cars descend this hill, potential energy is again changed to kinetic energy. This conversion between potential and kinetic energy continues throughout the ride.

Explanation: hi how ya doing  

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.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.
