Example of what happens to particles when their kinetic energy decreases?
Ann [662]

Explanation:

<h2>When we decrease the temperature, less heat energy is supplied to the atoms, and so their average kinetic energy decreases. When they enter a phase transition, such as freezing from a liquid to a solid, the temperature is not decreasing or increasing, and stays constant</h2>

A defibrillator containing a 18.4 μF capacitor is used to shock the heart of a patient by holding it to the patient's chest. Jus
gregori [183]

Answer:

The energy E is 1603.008 J.

Explanation:

Given that,

Capacitor = 18.4 μF

Voltage = 13.2 kV

We need to calculate the energy

Using formula of energy

E=W=\int{Q}\ dV.....(I)

We know that,

Q=CV

Put the value of Q in equation (I)

E=\int{CV}dV

On integration

E=\dfrac{CV^2}{2}

Put the value into the formula

E=\dfrac{18.4\times10^{-6}\times(13.2\times10^{3})^2}{2}

E=1603.008\ J

Hence, The energy E is 1603.008 J.
