A thin straight glass rod 550 cm long is placed on the x-axis so that it is symmetric about the y axis. An electrical charge Q = -328 mC is uniformly distributed over it. You will determine the electric field at a point P located at (0.00, 6.50 m). Problems 1a - 1e takes you, step by step, working through the problem. This gives practice in using the steps to solve this type of problem. (You are strongly advised to draw a figure depicting the information below. Drawing the figure should be very helpful in solving the problem.) The charge density of the rod is

Athermometer to measure the temperature of course 

Answer;

hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

explanation; convection currents are the circular pathways taken by a fluid that enhances heat transfer by the process known as convection which occurs in fluids.convection currents transfer heat from one place to another by mass motion of a fluid. earth mantle is in a semi-liquid state and behaves like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from heat of the earth's core, as the rock loses heat into the earth's crust it becomes cooler and more dense, then sinking back down to the core, then repeating the cycle.

Iwould say i also took the quiz but it didn't show me if i got it correct or not.
