Keona donates 1 ml of blood 473.176 times.
Each ml of blood has 1.06 gm of mass in it.
So the total mass of the blood is

                   (1.06 gm/ml) x (473.176 ml)  =  501.566 grams

  Rounded to the nearest hundredth, that's  501.57 grams.

Why are most of the world’s deserts located between latitudes 10°n to 30°n and 10°s to 30°s.
RoseWind [281]

The bulk of the world's deserts are located at 30 degrees north latitude and 30 degrees south latitude, when the warm equatorial air begins to descend. The heavy, warm, descending air vaporises large amounts of water from the ground's surface. As a result, the environment is rather dry.

<h3>Why are the majority of the desert regions on Earth located between 20 and 30 degrees latitude?</h3>

The zones of falling air are those between 20 and 30 latitudes on the western borders of continents (high pressure and dry weather). As a result, the moisture continues to decrease as the air is compressed and warmed as it falls.

Where the scorching equatorial air starts to descend, the majority of the world's deserts are found between 30 degrees north and 30 degrees south latitude. Large volumes of water are vaporised off the surface of the ground by the thick, warming, falling air. As a result, the climate is extremely dry.

What is the velocity of a narwhal that swims 76 kilometers North in 3 hours
tino4ka555 [31]

Answer:

<h3>25km/hr</h3>

Explanation:

Velocity is the change in displacement of a body with respect to time.

Velocity - Displacement/time

Given

displacement = 76km

Time = 3hours

Substitute the given parameters into the formula;

Velocity = 75km/3hrs

Velocity = 25km/hr

Hence the velocity of the narwhal is 25km/hr

Sauron [17]

Answer:

30.0625 W

Explanation:

325 g/h   x    (1h x 1kg)/(3600s x 1000g)   x   3,33 x 10^5 J/Kg = 30.0625 J/Kg = 30.0625 W

Find the acceleration of a box of mass 3.0 kg, if applied force is 20.0 N at 37° above the x axis, and the coefficient of kineti
ExtremeBDS [4]

Hello:

First, <u>the normal force</u> in y axis:

∑Fy = 0

∑Fy = N - Fy

∑Fy = N - 20 N * sen 37°

∑Fy = N = 12,87 N

Formula:

R = ma

F - F' = ma

F - (μN) = ma

20 N - (0.2 * 12,87 N) = 3 kg * a

20 N - 2.574 N = 3 kg * a

17,426 N / 3 kg = a

a = 5,8 m/s²
