g Which of the following statements regarding images of clouds taken from polar orbiting satellites are true? Choose all that apply. Group of answer choices continuously monitor weather over a particular region of the earth provide more detailed images than geostationary satellites monitor weather at the Earth’s poles orbit Earth at about 850 km above the surface orbit Earth parallel to meridian lines orbit the equator at a rate equal to that of Earth’s rotation on its axis

Rank the torques on the five doors shown in the figure above from least to greatest. note that the magnitude of all the forces is the same

Fft review: linspace, fs, fftshift, nfft 1. generate one second of a cosine of w,-10hz sampled at f, = 100hz and assign it to x. define a tt as your time axis 2. take 64 points fft. 3. as you remember, the dft (which the fft implements) computes n samples of s2t where k-0,1,2, n -1. plot the magnitude of this 64-points fft at range 0 to 63, what do you think of this graph? 4â·to get the x-axis into a hz-frequency form, plot this 64-points fft between-50 to 50 (the 100hz sampling rate) and have n-points between them. 5. according to your figure, what frequency is this cosine wave at? 6. remember that the fft is evaluating from 0 to 2ď€. we are used to viewing graphs from-ď€ to ď€. therefore, you need to shift your graph. 7. now according to your shifted graph. what frequency is this at? 8. note that the spikes have long drop-offs? try a 1024-point dft. note that the peak is closer to 10 and the drop-off is quicker. although, now sidelobes are an issue

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?
