The frequency range for a voice signal is 300 to 4000 HZ. The Nyquist theorem states a waveform should be sampled at 2 times its highest frequency. So 2 x 4000 is 8000 samples every second. This ensures an adequate representation of the signal.

You don't need to do a calculation here as it states that there are 47 frames every second
The deceleration is 5 metres per second per second or 5 ms-2
First of all, it doesn't. The hour-hand and minute-hand align in opposite directions only 22 times in 24 hours. The reason is simply because the hands of an ordinary 12-hour analog clock go through every possible orientation every 12 hours ... twice in 24 hours ... and if you take a clock, set it to 12:00, and then crank it through 24 hours, you'll see the hands line up in a 180-degree angle 22 times.
it shows the number of metres travelled every second. m/s
It means you multiply the binomial by itself. Multiplying polynomials requires multiplying every term of the first with every term of the second. For example, (a+b)2 = a2 + ab + ba + b2 = a2 + 2ab + b2.It means you multiply the binomial by itself. Multiplying polynomials requires multiplying every term of the first with every term of the second.
