Answer to Question 1

ANS: A
An aneroid manometer consists of a vacuum chamber with a flexible cover or diaphragm that flexes when pressure is applied to it. Electromechanical transducers use variable capacitance; strain gauge pressure transducers use Wheatstone bridge circuits; and variable inductance trans-ducers use the magnetic flux between two coils to measure pressure.

Answer to Question 2

ANS: B
Mouth pressure and box pressure changes are measured during tidal breathing and panting ma-neuvers.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
