Based upon the calculation of the force, Fapplied, calculated in the previous step, how much power must be put into the system in order to maintain the constant speed of the rail?

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

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.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
