Answer: 0.5
Explanation:
The modulus of elasticity (called <em>"alargamiento unitario"</em> in spanish) of a spring is given by the following formula:
Where:
is the original length of the spring
is the elongation of the spring, being the length of the spring after a force is applied to it.
Then:
Answer:
a).
b).
c.) It must be at the bottom
Explanation:
Given:
Volume flow
Well depp
a.
The power output of the pum
b.
The pressure of difference the pum
Δ
Δ
c.
It must be at the bottom since the pressure difference is greater than atmospheric pressure, so it wouldn't be able to lift the water all the way
I say that the answere would be B
Answer:
The pressure difference will increase by the factor of 1.75
Explanation:
For constant flow rate, coefficient of viscosity, length of the vessel and the pressure difference is inversely proportional to the fourth power of the radius of the blood vessel
Apply the principle of Poiseuille’s law.
Q = (P2 - P1)/R
