Place a T beside those statements you think are true and a F beside those statements you think are false. Anticipation Statements:
1.
Scientists can test whether it is right or wrong to cut down trees for farmland.
2. True science builds knowledge by following a specific method to collect data.
3. The natural cycles of Earth continue and are unaffected by human impact.
4. Mining underground causes less environmental damage than surface mining.
5. All physical environments on Earth have the same characteristics.
6. Waste in landfills can be reused for other purposes.

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

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
