Consider a blood vessel of constant diameter and fixed length. Which equation expresses the relation between pressure gradient (ΔP), blood flow (F), and resistance (R)? Remember that the Greek letter Δ (delta) means the difference in pressure between one end of the vessel and the other end

A) F = R / ΔP

B) ΔP = F / R

C) R = ΔP * F

D) F = R4

E) ΔP = F * R

E) ΔP = F * R

Explanation:

Let's look at Ohm's law:

ΔV = I * R

where I is the electric current, ΔV is the potential difference and R is the resistance.

We can derive the relationship between pressure gradient (ΔP), blood flow (F), and resistance (R) by analogy, getting:

ΔP = F * R

or

F = ΔP/R

This means that the flow is proportional to the pressure difference and inversely proportional to the resistance.

it takes about 30 days for it to break down

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
