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

Answer:
The correct option is;
D. The use of witchcraft to curse a person
Explanation:
The power of sorcery is widely believed among the Baloch, to be a negative power with the ability to cause many types illnesses, diseases and other forms of misery
By sorcery, supernatural power is used by persons to bring about losses, diseases, or death. When persons fall ill and the ailment is attributed to sorcery, the person is treated by a person that can ill through the powers available in a religion or by a sorcerer through ritualistic spells to cast out the evil (spirits and/or incantations)
Heart attacks happen suddenly when one of the arteries leading to the heart becomes blocked and cuts off the blood flow. Without oxygen, the heart muscles start to die.
Heart failure, on the other hand, usually develops gradually. The heart muscle becomes weaker and has trouble pumping blood to nourish the cells in your body. This is a chronic condition that gradually gets worse. But medications can help you live longer and better with it
