question 28

Multiple Choice

Which of the following statements is true?

• A) As the lung expands, the pressure within the lung increases, so air moves in until the pressure inside the lung is equal to the pressure outside the body.
• B) As the lung expands, the pressure within the lung decreases, so air moves in until the pressure inside the lung is equal to the pressure outside the body.
• C) As the lung expands, the pressure within the lung decreases, so air moves out until the pressure inside the lung is equal to the pressure outside the body.
• D) As the lung expands, the pressure within the lung decreases, so air moves out until the pressure inside the lung is greater than the pressure outside the body.

Definitions:

Inductance

The property of an electrical conductor by which a change in current in the conductor induces a voltage in both the conductor itself and in any nearby conductors by electromagnetic induction.

RLC Series Circuit

An electrical circuit consisting of a resistor (R), inductor (L), and capacitor (C) connected in a single line, forming a sequence of elements.

Power Factor

The ratio of the true power transmitted to a load to the apparent power in the circuit, indicating efficiency in electrical systems.

RLC Parallel Circuit

An electrical circuit consisting of a resistor (R), inductor (L), and capacitor (C) connected in parallel, affecting the circuit's impedance and frequency response.
