What is the pressure exerted by 100 N force on a circular surface of radius 10 m ? ( Area of circle should be used ) ANSWER FAST
Tcecarenko [31]

Answer:

0.318 Pa

Step-by-step explanation:

Area of a circle= πr²

Area= π x 10²

Area= 314 m²

Pressure = force/area

Pressure = 100/314

Pressure = 0.318 Pa

P.S. You can substitute Pascals for N/m²

Hope this helps!

An analog signal with a bandwidth of 36MHz is sampled at a frequency (fs) of 36,000,000 samples per second during the ADC (analo
Elza [17]

Answer:

The signal would have experienced aliasing.

Step-by-step explanation:

Given that:

the bandwidth of the signal f_m = 36MHz

= 36 × 10⁶ Hz

The sampling frequency f_s = 36 × 10⁶ Hz

Suppose the sampling frequency is equivalent to the bandwidth of the signal, then aliasing will occur.

Therefore, according to the Nyquist criteria;

Nyquist criteria posit that if the sampling frequency is more above twice the maximum frequency to be sampled, a repeating waveform can be accurately reconstructed.

∴

By Nyquist criteria, for perfect reconstruction of an original signal, i.e. the received signal without aliasing effect;

Then,

f_s \geq 2f_m

∴

The signal would have experienced aliasing.
