In an experiment Erin holds two objects. Object A has a net charge of β4.81 Γ 10β7 C, and object B has a net charge of 6.41 Γ 10β7 C. She touches the objects together.
(a) Roughly how many more electrons are there than protons in object A before the two objects come in contact?
(b) After Erin touches the objects together, about 5.00 Γ 1011 electrons transfer from object A to object B. What is the new net charge on object B?

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? 4Γ’Β·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 2Δβ¬. we are used to viewing graphs from-Δβ¬ to Δβ¬. 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
