Square energy pulse traveling to the right with a speed v=2 m/s is given by the equation: f(x, t)=e if |x-vt|a≤f(x, t)=0 if |x-vt|> awhere e is an energy constant and a a length constant. i) plot this pulse as a funtion of x at t=0.ii) plot this pulse as a function of x at t=4 s. iii) expand this pulse as an infinite superposition of harmonic traveling waves of the type cos(t-kx) where /k=v.

this is poiselle's equation from fluid mechanic in physics. mech eng

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.
