O avoid compromising your car's aerodynamic properties, you should avoid ________.

Biology
1 answer:
Len [333]3 years ago
8 0

Answer:

to carry heavy load on the vehicle's outside

Explanation:

Aerodyanmic properties of a car refer to its interactions with moving air and the properties which govern smooth movement of the car through air. Aerodynamics of a car address the concerns like lowering noise emission, prevention of heavy load and avoiding the luggage dragging.

Now when there will be great load outside the car,the air will resist the movement of car more, so it will be difficult for the car to cut through the air. Moreover, when a car carries huge amount of load outside its body, the frictional force by aerodynamic drag increases greatly. This can badly effect the performance of high speed cars like sports cars but for other normal cars it poses less hazards.

Hope it helps!

Please list and discuss the indications and steps used during endotracheal suctioning. Suggested Fundamentals Learning Activity:
vlabodo [156]

Answer:

need to be done with plenty of observation to avoid infection.

Explanation:

This technique is quite delicate because the main risk is infection. Some of the main risks are neuromuscular disease, sedation or neurological illness.

Another risk is that by passing the time, there is a difficult in respiratory, in this case, the main risk is directly to the heart, with some stoke, due to the high concentration of carbon dioxide due to the low exchange among oxygen and CO2.

Some of the indications are:

a.- Coarse crackles auscultated over trachea.

b.- Increase the respiratory pressure.

c.- Decrease tidal volume.

d.- Check the levels of oxygen in blood as in arteries.

e.- Check that patients can generate a cough.

Hope this info is useful.

According to the theory of island biogeography, which of the following is not an island ecosystem?
den301095 [7]
<span>The correct answer is b. The open ocean. The definition of an island ecosystem does not have anything to do with water, but simply refers to an ecosystem that exists as a microcosm within a far larger, separate ecosystem. The ocean has lots of separate island ecosystems within it, but it itself cannot be referred to as one.</span>

What is the Reynolds number for blood leaving the heart through the aorta if the diameter of the aorta is 2.15 cm and the blood
defon

Answer:

b. laminar flow

the reynold number is 1329.26

Explanation:

Re = (V x D x ρ)/ η

where,

V = mean velocity = 15.9 cm/s = 0.159m/s

D = vessel diameter = 2.15cm = 0.0215m

ρ = blood density = 1050 kg/m3 = 0.00105 kg/cm3

η = dynamic viscousity= 2.70 × 10-3 Pa·s = 2.70 × 10-3 kg/m-s

applying the formular to calculate for reynolds number, Re =

Re = (V x D x ρ)/ η

   =(0.159 x 0.0215 x 1050) / 2.70 × 10-3

   =3.589/0.0027 = 1329.26

the Reynolds number for the blood leaving the heart through the aorta if the diameter of the aorta is 2.15 cm and the blood has a dynamic viscosity of 2.70 × 10-3 Pa·s, a density of 1050 kg/m3, and travels at a mean fluid velocity of 15.9 cm/s is 1329.26

which flow through the aorta in a Laminar flow

Note that

a) turbulen= Re  >4000

b) laminar= Re  <2300

c) transitioning between laminar and turbulen= Re between 2100 and 4000
