Yaeji completed the attract or repel part of the table when she observed what happens when two charged objects come close to each other. Her teacher told her that there is a mistake in her table. How can Yaeji correct her table? A negatively charged glove and a positively charged dress will repel each other, so Yaeji should change "attract" to "repel" for these objects.

A negatively charged T-shirt and a positively charged chair will attract each other, so Yaeji should change "repel" to "attract" for these objects.

Two negatively charged beach balls will attract each other, so Yaeji should change "repel" to "attract" for these objects.

A negatively charged T-shirt and a positively charged dress will repel each other, so Yaeji should change "attract" to "repel" for these objects.

Under normal temperature and pressure conditions, what type of rock could be formed from weathering in erosion of metamorphic rock

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
