Consider a mass m moving in two dimensions with potential energy u (x, y) = 2 1 kr 2 , wherer 2 = x 2 + y 2 . write down the lagrangian, using coordinates x and y, and find the two lagrangeequations of motion. describe their solutions. [this is the potential energy of an ion in an "iontrap", which can be used to study the properties of individual atomic ions.]

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

i dont have a visual in front of me, but i can you reason to try to get the right one. the graph should look like this, 0 to 6 there is a spike, 12 to 14 there should be a very low point. slight increase in the graph at 12 to 14, and flat 14 to 18
