Explain why a battery causes charge to flow spontaneously when the battery is inserted in a circuit

1 answer:

3 0

Batteries supply electrons to the circuit by releasing negatively charged atoms or ions. These ions are produced by the batteries through a chemical reaction that spontaneously occurs within the battery. So the negative end of the battery pushes the ions towards the positive end of the circuit with the help of the voltage. This is why eventually, batteries "run out" when the electrode is used up and the chemical reaction can no longer continue.

The above stress can be also approximated by a sinusoidal function (i.e. sine wave) with an average 3,811 kPa, amplitude 430 kPa

stepan [7]

Answer:

306.08 kPa

Explanation:

Given data

Average stress of first wave = 3811 kPa

amplitude of first wave ( A1 ) = 430 kPa

Frequency of first wave = 6 Hz

<u>Determine the average stress of the second sinusoidal component in kPa </u>

Amplitude of the additional wave (A2add) = $\frac{A1}{2}$ = 430 / 2 = 215 kPa

next we will determine the resultant amplitude of the second wave

A2 = $\sqrt{A^{2} _{1} } + A^{2} _{2add} + 2A_{1}A_{2add} Cos\alpha$

= $\sqrt{430^2+ 215^2 + 2(430*215) * cos 90}$

= $\sqrt{184900 + 46225 }$

= $\sqrt{231155}$ = 480.79

hence the average stress of the second sinusoidal component

= $\frac{2A_{2} }{\pi }$

= $\frac{2 * 480.79 }{\pi }$ = 306.08 kPa
