the electric field associated with a wave is given by e(x, t) = 100 cos(wt-kz), + 200 cos(wt-kx _ π/2)az (6) what is thc polarization of this wavc?

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes
