Answer:
Taking into account that:
The flow velocity u of a fluid is a vector field
u = u (x, t)
What gives the velocity of a Fluid Plot at position x y time t.
q = || u ||
Now if the flow is continuous as it happens in the blood vessels then:
The flow of a fluid is said to be constant if it does not move over time, that is why the variant would be 0.
Explanation:
As for the pump with narrow vessels, there the area would be less, therefore the flow also and the flow velocity as well. Adding that the friction with the walls increases as it is narrower, thus generating an increase in pressure with the flow of the liquid.
So this is where we have to put emphasis on the biophysics branch that explains the following:
The Venturi effect is explained by the Bernoulli Principle and the principle of continuity of mass. If the flow rate of a fluid is constant but the section decreases, the speed necessarily increases after crossing this section. By the theorem of conservation of mechanical energy, if the kinetic energy increases, the energy determined by the value of pressure necessarily decreases.
Indeed, according to Bernoulli's principle:
P 1 + 21 ρv 12 + ρgh 1 = P 2 + 21 ρv 22 + ρgh 2
I don't know
Answer:
no
Explanation:
I wouldn't like to study zoonotic diseases as a veterinary scientist because zoonotic diseases are diseases that is passed from an animal to a human. This could potentially be life threatening which is why I wouldn't want to do that.
Answer:
The bladder stores urine, and the sphincter blocks urine from passing to the urethra.
Answer:
Explanation:
Headache is the most common symptom. Most symptoms resolve within 14 to 21 days. Although recovery plans are unique to each person, all involve mental and physical rest and a gradual return to activity
Answer:
The correct term is - extrinsic stain.
Explanation:
Extrinsic stains are normally present on the surface of a tooth and occur due to taking pigmented beverages such as coffee, tea, carbonated drinks, caramel coloring, and foods. Smoking cigarettes is also one of the reasons that can cause an extrinsic stain.
This can be removed by dentists or professionals like hygienists. The stain particles act on the outer surface of the teeth and pigmented them which cause stain yellowish or brownish in individuals.
Thus, the correct answer is - extrinsic stain.
