A magnetic field protects Earth from the Sun’s high-energy particles. What two processes are involved in the formation of Earth’s magnetic field? the movement of materials in Earth’s mantle and Earth’s rotation
the movement of metals in Earth’s core and Earth’s rotation
the movement of solar wind toward Earth and Earth’s revolution
the movement of eruptions from the Sun’s surface and Earth’s revolution

You can watch static electricity in action by rubbing an inflated balloon against your hair. your hair will actually stand on its end! it does this because each hair becomes charged, and they all repel one another.

Ais not a mixture. colloid compound suspension solution

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.
