The lung volume that represents the maximum amount of exchangeable air is the _____

Savatey [412]

The lung volume that represents the maximum amount of exchangeable air is the: <u>vital capacity</u>

<u></u>

The vital capacity is the volume of air that can be taken into the lungs by inhaling and expelling air by inspiration and expiration.

<h3>What are the lungs? </h3>

The lungs are one of the largest organs of the body and are in charge of the respiratory function. They have a spongy appearance and are located in the thorax, protected by the ribs, one on each side of the heart.

To determine the trajectory of the movement of a material point in the xOz plane that is subjected simultaneously to oscillation

nasty-shy [4]

We are to show that the given parametric curve is a circle.

The trajectory of a circle with a radius r will satisfy the following relationship:

$(x-x_c)^2 + (y-y_c)^2 = r^2$

(with (x_c,y_c) being the center point)

We are given the x and y in a parametric form which can be further rewritten (using properties of sin/cos):

$x(t) = A\sin \pi(t+1) = A\sin (\pi t + \pi) = -A\sin \pi t\\y(t) = A\sin (\pi t + \frac{\pi}{2}) = A\cos \pi t$

Squaring and adding both gives:

$x^2(t) + y^2(t) = A^2(-1)^2\sin^2 \pi t + A^2 \cos^2 \pi t = A^2\\\implies x^2 + y^2 = A^2$

The last expression shows that the given parametric curve is a circle with the center (0,0) and radius A.

Suppose that a tiny space invader (m=0.47 kg) and the new space station orbit Earth at the same height from Earth’s surface. Whi

Ad libitum [116K]

The tiny space invader and the new space station will have equal orbital speed.

<h3>The orbital speed of satellite </h3>

The orbital speed of satellite on Earth surface is given as;

$V = \sqrt{\frac{GM}{r} }$

where;

V is the orbital speed
G is universal gravitation
M is mass of the Earth
r is the radius of the circular path

Since the two objects are at the same height from Earth's surface, the distance from the central point (r) will be the same. Thus, the two objects will have equal orbital speed.
