Energy is "the ability to do work". Energy is how things change and move. It takes energy to cook food, to drive to school, and to jump in the air. Different forms of Energy. Energy can take a number of different forms.
The structure of an atom is in the middle of an atom has the neutron (nucleus) which has no charge around the neutron is the protons which has a positive charge and the ones that orbit around the atom is the electrons which has a negative charge in it. The number of protons is call the Atomic Number. Protons have a relative charge of +1 and the electron have a relative charge of -1.

Explanation:
The angular displacement through which the wheel turned can be determined from the equation below:
(1)
where
Using these values, we can solve for from Eqn(1) as follows:
or
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>
