The discovery that most galaxies have red shifts implies that

implies that the universe is expanding.

By the doppler shift, you can have two shifts, the red implies that something is going further away from you, and a blue shift means that something is coming towards you. So the fact that most galaxies are getting further away, implies that there is a expansion occurring.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

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
