On a roller coaster loop-the-loop the riders are upside-down at the top of the loop, while on a ferris wheel the riders are upright at the top. suppose a ferris wheel and the loop of a roller coaster have the same diameter. if riders on each have the same magnitude of apparent weight at the top, which rider is moving faster? explain.

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.

the total distance traveled by the car is

30km + 49km = 79 km .

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
