<span>This question is answered by using Boyle's law which states that P1V1=P2V2. Therefore 3ml x 810mmHg = 1.7ml * P2. P2 in this case is 1429mmHg. Air flow would be out of the body into the environment, where atmospheric pressure is approximately 760 mmHg. Higher pressure flows into lower pressure areas.</span>

The new pressure would be about 1430 mmHg.

Air would flow out of the alveolus.

\texttt{ }

<h3>Further explanation</h3>

The Ideal Gas Law and Work formula that needs to be recalled is:

\boxed {PV = nRT}

\boxed { W = P \Delta V }

<em>where:</em>

<em>W = Work ( J )</em>

<em>P = Pressure ( Pa )</em>

<em>V = Volume ( m³ )</em>

<em>n = number of moles ( moles )</em>

<em>R = Gas Constant ( 8.314 J/mol K )</em>

<em>T = Absolute Temperature ( K )</em>

Let us now tackle the problem !

\texttt{ }

<u>Given:</u>

initial volume = V₁ = 3 ml

initial pressure = P₁ = 810 mmHg

final volume = V₂ = 1.7 ml

<u>Asked:</u>

final pressure = P₂ = ?

<u>Solution:</u>

<em>We will use </em><em>Boyle's Law</em><em> to solve this problem as follows:</em>

P_1V_1 = P_2V_2

810 \times 3 = P_2 \times 1.7

P_2 = 2430 \div 1.7

P_2 \approx 1430 \texttt{ mmHg}

\texttt{ }

At sea level , the atmospheric pressure (Po) is about 760 mmHg.

Because P₂ > Po , air would flow out of the alveolus.

Answer:

Explanation:  

When objects collide, energy can be transferred from one object to another, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air; as a result, the air gets heated and sound is produced.

A toy rocket launcher can project a toy rocket at a speed as high as 35.0 m/s.
Anestetic [448]

Answer:

(a) 62.5 m

(b) 7.14 s

Explanation:

initial speed, u = 35 m/s

g = 9.8 m/s^2

(a) Let the rocket raises upto height h and at maximum height the speed is zero.

Use third equation of motion

v^{2}=u^{2}+2as

0^{2}=35^{2}- 2 \times 9.8 \times h

h = 62.5 m

Thus, the rocket goes upto a height of 62.5 m.

(b) Let the rocket takes time t to reach to maximum height.

By use of first equation of motion

v = u + at

0 = 35 - 9.8 t

t = 3.57 s

The total time spent by the rocket in air = 2 t = 2 x 3.57 = 7.14 second.

A diffraction pattern forms when light passes through a single slit. The wavelength of the light is 691 nm. Determine the angle
expeople1 [14]

Explanation:

Given that,

Wavelength of the light, \lambda=691\ nm=691\times 10^{-9}\ m

(a) Slit width, a=3.8\times 10^{-4}\ m

The angle that locates the first dark fringe is given by :

sin\theta=\dfrac{\lambda}{a}

sin\theta=\dfrac{691\times 10^{-9}}{3.8\times 10^{-4}}

\theta=0.104^{\circ}

(b) Slit width, a=3.8\times 10^{-6}\ m

The angle that locates the first dark fringe is given by :

sin\theta=\dfrac{\lambda}{a}

sin\theta=\dfrac{691\times 10^{-9}}{3.8\times 10^{-6}}

\theta=10.47^{\circ}

Hence, this is the required solution.

(Briefly explain what would happen, if there is no existence of capacitor in our world?​
skelet666 [1.2K]

If there is no existence of capacitors in our world there would be no electrical or electronic engineering.

A capacitor is a device that stores electrical energy in an electric field. It has two terminals and is a passive electrical component. Capacitance refers to a capacitor's effect. A capacitor commonly referred to as a condenser is one of the fundamental parts needed to create electronic circuits. Without fundamental parts like resistors, inductors, diodes, transistors, etc., a circuit's design is incomplete or it won't work properly.

Energy storage is capacitors' most popular application. Power conditioning, signal coupling or decoupling, electronic noise filtering, and remote sensing are further applications. Capacitors are employed in a wide variety of industries and have integrated into daily life due to their numerous applications.

There are numerous significant uses for capacitors. They are employed in digital circuits, for instance, to prevent the loss of data saved in big computer memories during a brief loss of power. The electric energy held in such capacitors keeps the data from being lost during a brief power outage.
