Suppose you measure a standing person's blood pressure by placing the cuff on his leg 0.470 m below the heart. calculate the pre

ssures you would observe (in units of mm hg) if the pressure at the heart were 120 over 80 mm hg. assume there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large).

The first pressure is illustrative of the maximum output of the heart; the second is because of the elasticity of the arteries in upholding the pressure between beats. Solution:760 mm HG is equivalent to 13.6*.760 m =10.34 m H2O 
Then multiply: 470/10.34 * 760mmHg to each of the readings. The answer is about 35 mmHg add this to the current reading of 120/80
Therefore:ΔP=35 mm Hg,Leg blood pressure is 155/115.

Calculate the momentum value of .... (Include appropriate units on your answers.)
vekshin1

Given :

Mass of brick, m = 2 kg.

Speed of block, v = 12 m/s .

To Find :

The momentum of the brick.

Solution :

We know, momentum of any object is given by :

Momentum = Mass × Speed

Momentum = m × v

Momentum = 2 kg × 12 m/s

Momentum = 24 kg m/s

Therefore, the momentum of the brick is 24 kg m/s .

Dielectric breakdown in air occurs when the electric field is approximately 3 × 106 V/m.What would be the peak magnetic field in
Svet_ta [14]

Answer:

10 mT

Explanation:

The relationship between electric field magnitude and magnetic field intensity in an electromagnetic wave is

E=cB

where

E is the magnitude of the electric field

c is the speed of light

B is the magnitude of the magnetic field

In this problem, we have

E=3\cdot 10^6 V/m is the electric field

c=3\cdot 10^8 m/s is the speed of light

Solving the equation for B, we find

B=\frac{E}{c}=\frac{3\cdot 10^6 V/m}{3\cdot 10^8 m/s}=0.01 T=10 mT

Lilli suggests that they explore the simulation starting with varying only a single parameter in order to understand the role of
mrs_skeptik [129]

Answer:

B.

Explanation:

One of the ways to address this issue is through the options given by the statement. The concepts related to the continuity equation and the Bernoulli equation.

Through these two equations it is possible to observe the behavior of the fluid, specifically the velocity at a constant height.

By definition the equation of continuity is,

A_1V_1=A_2V_2

In the problem A_2 is 2A_1, then

A_1V_1=2A_1V_2

V_2 = \frac{V_1}{2}

<em>Here we can conclude that by means of the continuity when increasing the Area, a decrease will be obtained - in the diminished times in the area - in the speed.</em>

For the particular case of Bernoulli we have to

P_1 + \frac{1}{2}\rho V_1^2 = P_2 +\frac{1}{2}\rho V_2^2

P_2-P_1 = \frac{1}{2} \rho (V_1^2-V_2^2)

For the previous definition we can now replace,

P_2-P_1 = \frac{1}{2} \rho (V_1^2-(\frac{V_1}{2})^2)

\Delta P =  \frac{3}{8} \rho V_1^2

<em>Expressed from Bernoulli's equation we can identify that the greater the change that exists in pressure, fluid velocity will tend to decrease</em>

The correct answer is B: "If we increase A2 then by the continuity equation the speed of the fluid should decrease. Bernoulli's equation then shows that if the velocity of the fluid decreases (at constant height conditions) then the pressure of the fluid should increase"
