Particulate matter in the inhaled air is trapped by the __________.

Physics
1 answer:
VladimirAG [237]2 years ago

Answer:

Particulate matter in the inhaled air is trapped by the <u><em>epithelial mucus.</em></u>

Explanation:

The complete question is:

<em>"Particulate matter in the inhaled air is trapped by the __________. </em>

<em>a. tracheal carina </em>

<em>b. paranasal sinuses </em>

<em>c. pharyngeal muscles </em>

<em>d. epithelial mucus"</em>

The nostril is covered with a mucous membrane that, at its highest part, is formed by an epithelium that contains cells that produce mucus and hair cells covered with fine hairs, called vibratil cilia. Epithelial cells help protect against the entry of microorganisms. In other words, certain types of epithelial cells have tiny hairs called cilia, which help remove foreign substances.

So, <u><em>particulate matter in the inhaled air is trapped by the epithelial mucus.</em></u>

a 4kg box is resting on top of a shelf that is 2m high, what is the boxs gravitational potential relative to the floor​
Aloiza [94]

Answer:

80 J

Explanation:

PE = mgh

PE = (4 kg)(9.8 m/s^2)(2 m)

PE = 78.4 J and with sig figs, it would be 80 J

a 1600 kg car on flat ground is moving 6.25 m/s. its engine creates 1150 N forward force as the car moves 45.8 m. what is it fin
Sveta_85 [38]

Answer:

83,900 J

Explanation:

First, find the acceleration:

F = ma

1150 N = (1600 kg) a

a = 0.719 m/s²

Now find the final velocity.

Given:

Δx = 45.8 m

v₀ = 6.25 m/s

a = 0.719 m/s²

Find: v

v² = v₀² + 2aΔx

v² = (6.25 m/s)² + 2 (0.719 m/s²) (45.8 m)

v = 10.2 m/s

Now find the final KE:

KE = ½ mv²

KE = ½ (1600 kg) (10.2 m/s)²

KE = 83,920 J

Rounded to three significant figures, the final kinetic energy is 83,900 J.

Carla holds a ball 1.5 m above the ground. Daniel, leaning out of a car window, also holds a ball 1.5 m above the ground. Daniel
spayn [35]

Answer:

Carla

Explination: As Daniel's ball is dropped from the car moving at 40 mph in a horizontal direction, at the time the ball is dropped it is also moving at 40 mph in a horizontal direction due to inertia, a property of mass causing resistance to change, Daniel's ball will continue to move in a horizontal direction even after being dropped along with falling due to gravity. Daniel's ball will then fall in a projectile motion curve of sorts which will cause an overall velocity to not be straight down causing it not to fall to the ground as quickly as Carla's ball.

Sorry for the long explanation
