a student places a 10 g coin on a disk at a point 0.02 m from the center of the disk. the student rotates the disk with a steadily increasing speed. at what speed will the coin start to slide off the disk if the coefficient of static friction between the coin and the disk is 0.47?

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

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
