Explain how smoking damages the respiratory system and name two conditions that can develop when a person smokes. ribe the location and importance of cilia and mucus in the respiratory system.
Answer:
Smoking damages the respiratory system by irritating the trachea and larynx due to the toxic chemicals and by causing swelling and narrowing of the airways and excess mucus in the lung passages. Two conditions that can develop when a person smokes is breathlessness and reduced lung function.
Explanation:
Smoking causes damages to the respiratory system by narrowing the airways and filling an excess of mucus in the lungs. It is a bad habit that may cause emphysema and chronic bronchitis.
Cigarettes contain more than 500 chemical substances in addition to nicotine, an addictive substance found in tobacco.
Cilia are hair-like projections localized in the airways that act to eliminate mucus and foreign (potentially harmful) matter.
The toxic compounds contained in cigarettes can paralyze the cilia in the airways and destroy them.
Smoking may produce:
The irritation and inflammation of the components of the respiratory system (e.g., trachea, larynx, lungs, etc)BreathlessnessExcess of mucous secretion in the lungs.Irreversible damage in the small air sacs of the lungs.In consequence, smoking is associated with chronic obstructive pulmonary diseases, including chronic bronchitis or emphysema.
In conclusion, smoking causes damages to the respiratory system by narrowing the airways and filling an excess of mucus in the lungs. It is a bad habit that may cause emphysema and chronic bronchitis.

A student is preparing to take a bath when she realizes the hot water tap in the bathroom is not working the student go to the kitchen and prepares 10 of 100°C water to mix with 10 L of 10°C water
Answer:
The final temperature of the bath water will be 55°C
Explanation:
A student is preparing to take a bath when she realizes that the hot water tap is not working.
The student goes to the kitchen and prepares 10 L of 100 degree Celsius water to mix with 10 L of 10 degree Celsius water. What will be the final temperature of the bath water?
Using the relation, Heat lost = Heat gained (assuming no heat is lost to the surroundings).
Heat lost by hot water = heat gained by cold water
Using the formula of heat, Q = mcΔT
where m = mass of water, c = specific heat capacity of water, ΔT = temperature difference
mass of water = density * volume (density of water = 1 kg/L)
mass of hot water, m₁ = 1 kg/L * 10 L = 10 kg;
mass of cold water, m₂ = 1 kg/L * 10 L = 10 kg;
specific heat capacity of water, c = 4200 j/kg
Let the final temperature of the mixture be T
-m₁cΔT₁ = m₂cΔT₂ ( since heat is lost by the hot water)
-m₁ΔT₁ = m₂ΔT₂
-10 * (T- 100) = 10 * (T - 10)
-10T + 1000 = 10T - 100
20T = 1100
T = 1100/20
T = 55°C
Therefore, the final temperature of the bath water will be 55°C

If a bat exerts a 350N rightward force on a
baseball, how much force is the baseball exerting
on the bat?
Answer:
350N
Explanation:
According to Newton's 3rd law of motion, 2 objects that interact experience an equal and opposite force on each other. So if the bat exerts 350N of force on the baseball, the baseball must exert 350N on the bat.
This, in case you were interested, is what causes the recoil of the bat.

What is electric current?Electric current is the flow of electric charge through a conducting material, such as a wire. It is measured in units of amperes (A), which represents the rate of flow of electric charge.
The standard definition of electric current is that it is the amount of electric charge passing through a given area of a conductor in unit time.
Mathematically, electric current is expressed as:
I = Q / t
Where
I = the electric current,
Q =the amount of electric charge that flows through a conductor,
t = the time interval during which the charge flows.
The unit of electric charge is coulombs (C), which represents the charge carried by a current of one ampere flowing for one second. So, one ampere of electric current represents a flow of one coulomb of electric charge per second.
Electric current is typically measured using an ammeter, which is a device that is inserted in series with a circuit to measure the current flowing through it. The ammeter is designed to have very low resistance, so it does not significantly affect the current flowing through the circuit being measured.
Here in the question,
If the change in velocity increases, the acceleration during the same time period increases as well. This is because acceleration is directly proportional to the change in velocity over time, as expressed by the formula:
a = (v_f - v_i) / t
Where
a = acceleration,
v_f = the final velocity,
v_i = the initial velocity,
t = the time interval during which the velocity changes.
If the change in velocity is greater, the numerator of the equation is larger, and therefore, acceleration is greater. Similarly, if the time interval is kept constant, an increase in velocity change leads to an increase in acceleration.
Therefore, when velocity increases the acceleration also increases.

Acartravelingat15m/sstartstodeceleratesteadily.Itcomestoacompletestopin10seconds.Whatisit'sacceleration? a. 1500 m/s b. -1.5 m/s c. 1.5 m/s d. 150 m/s
Answer:
b. -1.5 m/s²
Explanation:
Given the following data;
Initial velocity = 15m/s
Time = 10 seconds.
Since the car came to rest, final velocity = 0m/s
To find acceleration;
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of final speed from the initial speed all over time.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{initial \; speed - final \; speed}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]
v and u is initial and final speed respectively, measured in [tex]ms^{-1}[/tex]
t is time measured in seconds.
Substituting into the equation, we have;
[tex] Acceleration, a = \frac{0 - 15}{10}[/tex]
[tex] Acceleration, a = \frac{-15}{10}[/tex]
Acceleration = -1.5 m/s²
How would the force between two charged particles change if one of the charges were to triple in strength (3x stronger)?
A. 9x stronger
B. 1/3 as strong
C. 1/9 as strong
D. 3x stronger
Answer:
The correct option is (d). "3x stronger".
Explanation:
The force between two charged particle is given by :
[tex]F=k\dfrac{q_1q_2}{r^2}[/tex]
If one charge is tripled, [tex]q_1'=3q[/tex]
New force will be :
[tex]F'=\dfrac{kq_1'q_2}{r^2}\\\\=3\times F[/tex]
It means if one of the charges were to triple in strength, then the force will become 3 times of the initial force.

A 7.00 kg ball hits a 75.0 kg man standing at rest on ice. The man catches the ball. How fast does the ball need to be moving in order to send the man off at a speed of 3.00 m/s?
Answer:
35.14 m/s
Explanation:
The Law of Conservation of Momentum states that the momentum before and after a collision is the same.
m₁ v₁ + m₂ v₂ = m₁ v₁ + m₂ v₂Let's set the ball to have the subscript of 1 and the man to have the subscript of 2.
The initial and final mass of the ball is the same, so m₁ = 7.00 kg on both sides of the equation.
The initial velocity of the ball, v₁ on the left side of the equation, is the unknown variable we are trying to find.
The initial and final mass of the man is the same, so m₂ = 75.0 kg on both sides of the equation.
The man starts at rest, meaning that his initial velocity is v₂ = 0 m/s on the left side of the equation.
The final velocity of both the ball and the man is 3.00 m/s, so we can set v₁ and v₂ on the right side of the equation to equal 3.00 m/s.
Left side of the equation:
m₁ = 7.00 kg v₁ = ?m₂ = 75.0 kgv₂ = 0 m/sRight side of the equation:
m₁ = 7.00 kg v₁ = 3.00 m/sm₂ = 75.0 kgv₂ = 3.00 m/sSubstitute these values into the Law of Conversation of Momentum formula.
(7.00) v₁ + (75.0)(0) = (7.00)(3.00) + (75.0)(3.00)Multiply and simplify.
7.00 v₁ = 21 + 225 7 v₁ = 246Divide both sides of the equation by 7.
v₁ = 35.14 m/sThe ball needs to be moving at a speed of 35.14 m/s in order to send the man off at a speed of 3.00 m/s.
