A500 kg piano is being lowered into position by a crane while two people steady it with ropes pulling to the sides. bobs rope pulls to the left, 15 degrees below horizontal, with 410 n of tension. ellen's rope pulls toward the right, 26 degrees below horizontal.

part a
what tension must ellen maintain in her rope to keep the piano de ending at a steady speed?

partb
what is the tension is the vertical main cable supporting the piano?

The answer above is incorrect because the degrees are switched. If you switch the 15 degrees and 26 degrees and substitute them into where they are incorrectly placed, then you get the correct answer.

Explanation:

current flows in a wire

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.
