Answer:
c.
Explanation:
When you take samples of an analog signal, you must take samples fast enough so then you can recover the original signal, just passing the digitized signal through a low-pass filter.
The Nyquist criteria states that in order to be able to recover the original signal completely, you must take samples at a rate greater than 2 times the highest frequency component of the signal.
In our case, we should sample the analog signal at a rate > 2*5500 Hz = 11000 Hz.
If we sampled the 5500 Hz signal (assuming be a sinusoid just for simplicity) two times each cycle, we could be so unfortunate that the samples fall exactly when the signal crosses by zero, so the digitized signal would be only a train of zeros.
So, if we sample the signal only one time in each cycle, clearly we will not be able to recover the signal, and the digital signal will experience aliasing, due we are not following Nyquist sample rate requirements, as stated in the option c.

Hello.
BEVs and hydrogen fuel cell vehicles are a more promising transportation technology for the future because they reduce greenhouse gas emissions as well as CO2 making it more 'green.' The second question is your opinion, in mine no, they should not be required but they should at least be considering.
Have a nice day
An initial velocity is:
v o = 25 m/s
The vertical component of the initial velocity:
v o y = v o * sin 60° =
= v o * √3 / 2 = 25 m/s * √3 / 2 = 21.65 m/s
Answer:
The approximate vertical component of the initial velocity is 21.65 m/s.
