Answer:

a. Mucous membranes protect the inside parts of your body that are exposed to air, in a similar fashion to how your skin protects your external body. Mucous membranes are rich with mucous glands that secrete mucus to help keep the membranes moist.

b.Nose hairs act as a filter that prevents dust, pollen, and allergens from entering your lungs. When particles enter your nose, they get stuck on a thin layer of mucus that coats your hairs. Eventually, the particles either get sneezed out or swallowed. Your nose is also filled with microscopic hairs called cilia.

.

c.The epiglottis is a small, movable "lid" just above the larynx that prevents food and drink from entering your windpipe. But if the epiglottis becomes swollen — either from infection or from injury — the airway narrows and may become completely blocked.

d.Coughing can have causes that aren't due to underlying disease. Examples include normal clearing of airways, irritants such as smoke and gas, tobacco use or improperly swallowing food and liquids.

e.In humans there are about 15 – 20 incomplete C-shaped cartilaginous rings which reinforces the anterior and lateral sides of the trachea to protect and maintain the airway open. (The cartilaginous rings are incomplete because this allows the trachea to collapse slightly to allow food to pass down the esophagus.

f. .Pulmonary surfactant is a surface active material composed of lipids and proteins which is found in the fluid lining the alveoli.

g.The pleura includes two thin layers of tissue that protect and cushion the lungs. ... The very thin space between the layers is called the pleural cavity. A liquid, called pleural fluid, lubricates the pleural cavity so that the two layers of pleural tissue can slide against each other.

h.The ribs are the bony framework of the thoracic cavity. The ribs form the main structure of the thoracic cage protecting the thoracic organs, however their main function is to aid respiration. There are twelve pairs of ribs. Each rib articulates posteriorly with two thoracic vertebrae by the costovertebral joint.

The force of the floor on the briefcase

Explanation:

The briefcase hits the floor and stops the falling which is reacting to the briefcase that was falling and hits the floor.

The falling briefcase would be the action force because it is moving downward

and

The reaction force would be the floor because it will react on the briefcase.

Hope this Helps

When the briefcase lands on the floor, the reaction force to the action force of the briefcase on the floor is  force of the floor on the briefcase.

It might be difficult to distinguish between action and reaction forces. This is due to the fact that both forces are always present.

One might argue that there are an equal number of forces in the universe if one were to count them all. However, the definition of the action force is provided by the perspective of the interaction analysis in order to help the argument.

A force that is applied to an object is known as an action force.

An action force with an opposite direction has an effect called a reaction force.

These two forces—also referred to as action and reaction forces—are covered by Newton's third law of motion.

The rocket's initial upward acceleration is 15 m/s^2.

To find the rocket's initial upward acceleration, we need to use Newton's second law of motion, which states that the force applied to an object is equal to its mass multiplied by its acceleration:

F = m × a

Where F is the force applied, m is the mass of the object, and a is its acceleration.

In this problem, we know that the mass of the rocket is 20000 kg, and the rocket motor generates a force of 3.0×10^5 N in the upward direction. Therefore, we can calculate the rocket's initial upward acceleration as follows:

F = m × a

3.0×10^5 N = 20000 kg × a

a = 3.0×10^5 N / 20000 kg

a = 15 m/s^2

An electric field is defined along the x-axis by the function then if g=1.5m and h=6m, then v(g)-v(h) = 7768.40V.

When charge is present in any form, a point in space has an electric field that is connected to it.

The value of E, often known as the electric field strength, electric field intensity, or just the electric field, expresses the strength and direction of the electric field.

Each location in space where a charge exists in any form can be considered to have an electric field attached to it. The electric force per unit charge is another name for an electric field. The electric field’s equation is given as E = F / Q.

E = + 5 x^4 x^n

Also, E = -x^n r/rx (v)

⇒ 5 x^4 x^n = -x^n r/rx (v)

⇒ v = - ∫ 5 x^4 dx

⇒ v = -5 x^5/5

⇒ v = - x^5 v

So, v(g) - v(h) = - (1.5)^5 + (6)^5

= -7.59375 + 7776

=7768.40 V

Answer:

Acceleration would be \(1.96\) times the initial value.

Explanation:

The vehicle is in a centripetal motion as it rounds the circular curve. Acceleration of the vehicle during the motion would be:

\(\displaystyle a = \frac{v^{2}}{r}\),

Where:

In this question, \(r\) stays the same since the vehicle is rounding the same curve. Acceleration of the vehicle would be proportional to the square of velocity.

The new velocity of the vehicle is \((70 / 50)\) times the original one. Hence, the new acceleration would be \((70 / 50)^{2} = 1.96\) times the original value.

A constant force applied to a 2.0 kg object at rest moves it 4.0 m in 2.0 seconds. The impulse of the force applied is 4kg m/s.

Impulse is a term which is used to describe or quantify the effect of force which is acting over time to change the momentum of an object. Impulse is represented by the symbol J and it is usually expressed in the SI unit as Newton-seconds or kg m/s.

Impulse = Change in momentum = ΔP

Momentum = m × v

ΔP = mv -mu

ΔP = 2.0 × 4/2 - 2.0 × 0

ΔP = 2.0 × 2 - 0

ΔP = 4kgm/s

The impulse of force applied is 4 kg m/s.

We have to calculate its range the horizontal distance covered by it when tossed from one teammate to the other.

range can be calculated by the formula :-

\( \boxed{\mathfrak{range = \frac{ u {}^{2} \sin 2\theta }{g} }} \)

u is the velocity during its take off and \(\theta\) is the angle at which its thrown

Given that

calculating range using the above formula

\( = \frac{ {8}^{2} \sin2(40) }{10} \)

\( = \frac{64 \times \sin(80) }{10} \)

value of sin 80 = 0. 985

\( = \frac{64 \times 0.985}{10} \)

\( = \frac{63.027}{10} \)

The net cell equation is Cu(s) + 2Ag+(aq) → Cu2+(aq) + 2Ag(s). E° cell = 1.10 V and ΔG°rxn = -200.6 kJ/mol.

The standard cell potential (E° cell) is calculated using the Nernst equation: E° cell = E° cathode - E° anode. The standard reduction potential of Cu2+ is 0.34 V and the standard reduction potential of Ag+ is 0.80 V. Therefore, E° cell = 0.80 V - 0.34 V = 0.46 V.

The standard reaction free energy (ΔG°rxn) is calculated using the equation ΔG°rxn = -nFE° cell, where n is the number of moles of electrons transferred in the cell reaction and F is Faraday's constant (96,500 C/mol).

The cell reaction involves two moles of electrons, so n = 2. Therefore, ΔG°rxn = -2(96,500 C/mol)(0.46 V) = -200.6 kJ/mol.

The lateral magnification of the object is 2.

The focal length of a lens is the distance from the lens' center to the point where the light rays converge (or appear to converge).

The power of a lens is determined by its focal length. The refractive index, or the bending of light, is determined by the curvature of the lens surface.

In the given scenario, the object's distance from the convex lens (converging lens) is 10 cm and the focal length is 20 cm.

We can use the formula for lateral magnification, which is:

M = v/u

Where v is the image distance and u is the object distance.

Since the image is formed on the other side of the lens, v will be negative.

u = -10 cm, as the object is located 10 cm from the lens on the opposite side of the image.

Magnification formula:

The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker. The sound source creates vibrations in the surrounding medium. because the supply continues to vibrate the medium, the vibrations propagate far from the supply at the rate of sound, hence forming the sound wave.
