Your heart pumps blood at a pressure of 100 mmHg and flow speed of 60 cm/s. At your brain, the blood enters capillaries with suc
Savatey [412]

Answer:

1.28 m

Explanation:

Generally, pressure of fluid is given by

P=\rho g h where g is acceleration due to gravity, h is the height and \rho is the density

Considering that the pressure for mercury is same as for blood only that the height and density of fluid are different then

\rho_b g h_b= \rho_m g h_m

Since g is constant, then

\rho_b h_b= \rho_m h_m

Making h_b the subject of the formula then

h_b=\frac {\rho_m h_m}{\rho_b}

Where subscripts m and b denote mercury and blood respectively

Assuming density of blood is 1060 Kg/m3, density of mercury as 13600 Kg/m3 and substituting height of mercury for 0.1 m then

h_b=\frac {13600*0.1}{1060}=1.283018868  m \approx 1.28 m

Why should you rotate food when thawing it 360 training?
Anni [7]

Rotation during thawing is necessary to ensure that your food reaches the right temperature in a secure and efficient manner. This prevents the ice from becoming stuck under some of the food. By rotating it, you can reveal any trapped, covered, or chunked ice.

<h3>What do you mean by Microwave oven?</h3>
  • A microwave oven, often known as a microwave, is an electric oven that uses electromagnetic radiation with a microwave frequency range to cook and heat food.
  • As a result, the food is heated via a process known as dielectric heating, which causes the polar molecules there to rotate and produce heat energy.
  • Because excitation is rather homogenous in the exterior 25–38 mm (1–1.5 inches) of a homogeneous, high water content food item, microwave ovens heat food fast and effectively.
<h3>What are the uses of a microwave oven?</h3>
  • A microwave oven, sometimes known as an electronic oven, is a device that uses microwaves, which are high-frequency electromagnetic waves, to cook food.
  • A microwave oven is a compact, box-shaped oven that increases food's temperature by exposing it to an electromagnetic field with a high frequency.

If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.
