The radius of the aorta is about 1.4cm , and the blood passing through it has a speed of about 40cm/s .
Lapatulllka [165]

For the average speed of blood flow in the major arteries of the body  is mathematically given as

v2 = 117.29m/s

<h3>What is the average speed of blood flow in the major arteries of the body?</h3>

Generally, the equation for the average speed  is mathematically given as

A1 v1 = A2 v2

(pi r1^2) v1 = A2 v2

(3.14x(1.4)^2 )x 40 = (2.1) xV2

v2 = 117.29m/s

In conclusion, the average speed of blood flow

v2 = 117.29m/s

1. Vertically oriented circular disks have strings wrapped around them. The other ends of the strings are attached to
Ymorist [56]

Answer:

See the answers and explanation below

Explanation:

To solve this problem, we must have the full description of this problem, by doing an internet search we can find a problem with the same description and with the respective question.

<u>Description of the problem</u>

<u />

"Vertically oriented circular disks have strings wrapped around them. The other ends of the strings are attached to  hanging masses. The diameters of the disks, the masses of the disks, and the masses of the hanging masses are

given. The disks are fixed and are not free to rotate. Specific values of the variables are given in the figures. Rank these situations, from greatest to least, on the basis of the magnitude of the torque on the disks. That is, put first the situation where the disk has the greatest torque acting on it and put last the situation where the disk has the least torque acting on it."

<u>For case D</u>

<u />

T = (20/2)*800 = 8000 [g-cm]

<u>For case A</u>

<u />

T = (20/2)*500 = 5000 [g-cm]

<u>For case C</u>

<u />

T = (10/2)*500 = 2500 [g-cm]

<u>For case B</u>

<u />

T = (10/2)*200 = 1000 [g-cm]

In this way it has been organized from the largest to the smallest torque present in each of the cases.

Harmonics problem. A square wave of frequency f contains harmonics (sine waves) at f, 3f, 5f, 7f, ... . Suppose a system respond
ad-work [718]

Answer:

C.

Explanation:

  • If the fundamental frequency of the square wave is 10 Khz, and contains harmonics at f, 3f, 5f, etc., it will have a component at 10 Khz, other at 30 Khz, and another one at 50 Khz.
  • If the system responds to frequencies in the range between 20 Khz and 40 KHz only, the shape of the response will contain only a 30 Khz sine wave (3rd harmonic of 10 Khz).

Johannes Kepler used math to show that the planets move in perfect circles around the sun.
svet-max [94.6K]
Kepler actually showed that the planets move around the sun in ellipses, not circles. So the answer is false.
