A particle executes simple harmonic motion with an amplitude of 2.48 cm. At what positive displacement from the midpoint of its motion does its speed equal one half of its maximum speed? Answer in units of cm.

pe = weightxheight = 2000x1000=2,000,000joules

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
