The lung volume that represents the maximum amount of exchangeable air is the _____
1 answer:
The lung volume that represents the maximum amount of exchangeable air is the: <u>vital capacity</u>
<u></u>
The vital capacity is the volume of air that can be taken into the lungs by inhaling and expelling air by inspiration and expiration.
<h3>What are the lungs? </h3>The lungs are one of the largest organs of the body and are in charge of the respiratory function. They have a spongy appearance and are located in the thorax, protected by the ribs, one on each side of the heart.

For the work-energy theorem, the work needed to stop the bus is equal to its variation of kinetic energy:
where
W is the work
Kf is the final kinetic energy of the bus
Ki is the initial kinetic energy of the bus
Since the bus comes at rest, its final kinetic energy is zero:
, so the work done by the brakes to stop the bus is
And the work done is negative, because the force applied by the brake is in the opposite direction to that of the bus motion.
