Answer:
<em>The signal x[n] = 16000 samples</em>
Explanation:
From the question,
S = x/t ................................... Equation 1
making x the subject of the equation
x = St .................................. Equation 2
Where S = sample rate ( samples per seconds), x = signal (samples), t = time ( seconds)
<em>Given: S = 8000 samples, t = 2 seconds.</em>
<em>Substituting these values into equation Equation 2</em>
<em>x = 8000×2</em>
<em>x = 16000 samples.</em>
<em>Thus the signal x[n] = 16000 samples</em>
Out of the choices given, when a light wave moves from a medium where particles of matter are closely packed to a medium made of little matter. You expect the light wave to move faster and increase its speed.
Electrons make a negative charge because electrons are negative. But when atoms lose electrons they make a positive charge.
