1 point in the same place higher lower to the right to the left 2. If the person generates a new pulse like the first but more quickly, the pulse would be 1 point same size wider narrower 3. If the person generates another pulse like the first but he moves his hand further, the pulse would be 1 point same size taller shorter 4. If the person generates another pulse like the first but the rope is tightened, the pulse will move 1 point at the same rate faster slower 5. If you advance the movie one frame, the knot at point A would be 1 point in the same place higher lower to the right to the left 6. If you advance the movie one frame, the pattern of the waves will be relative to the hand. 1 point in the same place shifted right shifted left shifted up shifted down 7. If the person starts over and moves his hand more quickly, the peaks of the waves will be 1 point the same distance apart further apart closer together

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

Will give brainliest! jay rides his 2.0-kg skateboard. he is moving at speed 5.8 m/s when he pushes off the board and continues to move forward in the air at 5.4 m/s. the board now goes forward at 13 m/s. a. determine jay’s mass. b. determine the change in the internal energy of the system during this process.(express your answer to two significant figures and include the appropriate units.)

Hey student studies gravity using objects that have the same mass which two objects have the greatest gravitational force acting between them a. 100kg 1.0m 100kg b. 100kg 2.0m 100kg c. 100kg 2.0m 100kg big d. 100kg big 3.0m 100kg big
