Explain why stones are strong in compression but weak in tension ​

Answers

Answer:

Gigantic towers, monuments and tall structures are always supported by a very thick layer of concrete that’s blended into their foundation. The purpose of this is quite straightforward: nothing provides greater support to a super heavy (and stationary) structure than a layer of concrete.  There may be other things that, in theory, could provide a stronger foundation, but they wouldn’t be nearly as cost effective as concrete.

Answer:

Because it has essentially zero strength in tension, it is almost always used as reinforced concrete, a composite material. It is a mixture of sand, aggregate, cement and water.

(b) The efficiency of the pump which operates the fountain is 70%.

Note: The question is incomplete. The complete question is given below:

On a day with no wind, a fountain in Switzerland propels 30000 kg of water per minute to a height of 140 metres.

a)Calculate the power used in raising the water?

b)The efficiency of the pump which operates the fountain is 70%

calculate the power supplied to the pump?

Explanation:

Efficiency = Power output/Power input * 100%

Power output = work done/ time

where work done = mass * acceleration due to gravity (g) * height

time = 1 minute = 60 seconds

mass of water = 30000 kg, height = 140 meters, g = 9.8 m/s²

Then, work done = 30000 * 140 * 9.8 = 41160000 J

Power output then = 41160000 J / 60 s

Power output = 686000 W

The power input can then be derived from the formula of efficiency

Power input = (Power output * 100)/Efficiency

Power input = (100 * 686000) / 70

Power input = 980000 W

Therefore, power supplied to the pump is 980000 W or 980 KW

you’ve learned about the intricate network of structures that comprise the respiratory system and how crucial it is to ensure that all pieces of this system remain in top condition. You also learned that smoking tobacco, cannabis, or other substances can have a significant impact on not only the overall health of the lungs but also has negative effects on all body systems. Using this new information, and with independent research, you are now asked to develop a learning package for someone who has come to you for health teaching. Imagine that you are either a nurse in a clinic, a personal trainer, a physiotherapist, or any other health practitioner who has just done an initial consultation with a patient. Your patient has disclosed that they smoke tobacco and they have indicated that they believe that the information about lung disease and smoking is fabricated and that it must be exaggerated. You are now tasked with showing them through a diagram and a verbal demonstration the true scientific facts around smoking and lung disease. Make sure to discuss the symptoms, prevention, diagnosis, and treatment in your demonstration. You will use either a diagram of the respiratory system that you’ve found online or one that you’ve drawn by hand to support your teaching. You will develop a script and teach the material to either an imaginary person or someone else and videotape your lesson.

How can smoking affect the respiratory system?

Smoking and Respiratory Disease

Smoking can cause lung disease by damaging your airways and the small air sacs (alveoli) found in your lungs. Lung diseases caused by smoking include COPD, which includes emphysema and chronic bronchitis. Cigarette smoking causes most cases of lung cancer.

Explanation:

I cannot create videos. However, I can help you develop a script for your health teaching package.

Your lungs and general health can be significantly impacted by smoking tobacco and other substances. It's crucial to comprehend the actual scientific data and take action to manage and avoid respiratory illnesses. Do not hesitate to ask if you have any queries or concerns.

What is the impact of smoking tobacco and other substances on the lungs and general health?

Hello, and thank you for coming to me for health teaching. I understand that you smoke tobacco, and you may have doubts about the impact it can have on your lungs and overall health. I'm here to show you the true scientific facts around smoking and lung disease.

Let's start with the respiratory system. The respiratory system is made up of many intricate structures that work together to deliver oxygen to your body and remove carbon dioxide. When you inhale smoke from tobacco or other substances, you introduce harmful chemicals into your lungs that can damage these structures.

Over time, smoking can lead to a range of respiratory diseases, including chronic bronchitis, emphysema, and lung cancer. Symptoms of these diseases can include coughing, wheezing, shortness of breath, and chest pain. These symptoms can significantly impact your quality of life and even be life-threatening.

Prevention is key when it comes to respiratory diseases caused by smoking. The best way to prevent these diseases is to quit smoking altogether. If you're struggling to quit, there are many resources available to help you, including nicotine replacement therapy and counseling.

If you're experiencing symptoms of a respiratory disease, it's important to seek medical attention. Your doctor can diagnose the disease and recommend a treatment plan that may include medication, lifestyle changes, and possibly surgery. Early diagnosis and treatment can greatly improve your chances of recovery and help you manage your symptoms.

Now, let me show you a diagram of the respiratory system so you can see how smoking affects it. [At this point, you can show the diagram and point out the different structures affected by smoking, such as the bronchi and alveoli.]

Therefore, smoking tobacco and other substances can have a significant impact on your lungs and overall health. It's important to understand the true scientific facts and take steps to prevent and manage respiratory diseases. If you have any questions or concerns, please don't hesitate to ask.

During heavy rain, a section of a mountainside measuring 1.9 km horizontally (perpendicular to the slope), 0.55 km up along the slope, and 2.4 m deep slips into a valley in a mud slide. Assume that the mud ends up uniformly distributed over a surface area of the valley measuring 1.4 km x 1.4 km and that the mass of a cubic meter of mud is 1900 kg. What is the mass of the mud sitting above a 3.5 m2 area of the valley floor

Answers

Answer:

the mass of the mud sitting above a 3.5 m2 area of the valley floor is 8509273.5 kg

Explanation:

Given the data in the question;

first we compute the total volume of mud

V = ( 1.9×1000)m × (0.55×1000)m × (2.4×1000)m

V = 2.508 × 10⁹ m³

same volume of mud spread uniformly over 1.4 × 1.4 km² area

Hence,

V = (1.4×1000)m × (1.4×1000)m × depth

2.508 × 10⁹ = 1400m × 1400m × depth

2.508 × 10⁹ m³ = 1960000m² × depth

depth = 2.508 × 10⁹ m³ / 1960000 m²

depth = 1279.59 m

so volume of the mud sitting above 3.5 m² area of the valley floor will be;

⇒ 3.5 m² × 1279.59 m

⇒ 4478.565 m³

so mass will be

m = 4478.565 × 1900 kg

m = 8509273.5 kg

Therefore, the mass of the mud sitting above a 3.5 m2 area of the valley floor is 8509273.5 kg

A long, thin metal tube of cross-sectional area 1.60 cm2 is sealed into the top of a hollow cube of edge length 0.150 m. Water fills the cube and extends upward a distance h into the tube. Find h if the water exerts a force of 1.00 103 N on the base of the cube. What is the weight of the water?

Answers

Answer:

Explanation:

Given that:

The area of the metal tube = 1.60 cm² = 1.60 × 10⁻⁴ m²

Length of cube L = 0.150 m

The exerted force by water = 1.00 × 10³ N

At the top of the cube;

The force on water is F = pgL

F = 9.8 m/s² × (1000 kg/m³) (0.150 m)(0.150 m)²

F = 33.075 N

[tex]pgh = \dfrac{F}{A}[/tex]

[tex]h = \dfrac{F}{Apg}[/tex]

[tex]h = \dfrac{33.075}{(1.60 \times 10^{-4} \ m^2) \times (1000 \ kg/m^3)(9.8)}[/tex]

h = 21.09 m

The volume of the water V = L³

V = (0.150 m)³

V = 0.003375 m³

weight of the water w = p(V + Ah)

w = 1000 (0.003375 + (1.60 × 10⁻⁴ × 21.09))

w = 6.75 kg

1. Calculate the electric field due to a single +1nC point charge at a distance of lm, 2m, and 3m

Answers

Answer:

Approximately [tex]9.0\; \rm N \cdot C^{-1}[/tex] at [tex]1\; \rm m[/tex] from this charge, pointing away from the point charge.Approximately [tex]2.2\; \rm N \cdot C^{-1}[/tex] at [tex]\rm 2\; \rm m[/tex] from this charge, pointing away from the point charge.Approximately [tex]1.0\; \rm N \cdot C^{-1}[/tex] at [tex]3\; \rm m[/tex] from this charge, pointing away from the point charge.

Assumption: there is no object between this point charge and the observer.

Explanation:

The electric field of a point charge is inversely proportional to the square of the distance from that point charge.

Let [tex]k[/tex] denote Coulomb's constant ([tex]k \approx 8.98755 \times 10^{-9}\; \rm N \cdot m^{2} \cdot C^{-1}[/tex].) Let the magnitude of that point charge be [tex]q[/tex]. At a distance of [tex]r[/tex] from this charge, the electric field due to this charge would be:

[tex]\displaystyle E = \frac{k \cdot q}{r^{2}}[/tex].

Convert the magnitude of the point charge in this question to standard units:

[tex]q = 1\; \rm nC = 10^{-9}\; \rm C[/tex].

Apply that equation to find the magnitude of the electric field due to this point charge:

[tex]r = 1\; \rm m[/tex]:

[tex]\begin{aligned} E &= \frac{k \cdot q}{r^{2}} \\ &= \frac{8.98755 \times 10^{-9}\; \rm N \cdot m^{2} \cdot C^{-2} \times 10^{-9}\; \rm C}{(1\; \rm m)^{2}} \\ &\approx 9.0\; \rm N \cdot C^{-1}\end{aligned}[/tex].

[tex]r = 2\; \rm m[/tex]:

[tex]\begin{aligned} E &= \frac{k \cdot q}{r^{2}} \\ &= \frac{8.98755 \times 10^{-9}\; \rm N \cdot m^{2} \cdot C^{-2} \times 10^{-9}\; \rm C}{(2\; \rm m)^{2}} \\ &\approx 2.2\; \rm N \cdot C^{-1}\end{aligned}[/tex].

[tex]r = 3\; \rm m[/tex]:

[tex]\begin{aligned} E &= \frac{k \cdot q}{r^{2}} \\ &= \frac{8.98755 \times 10^{-9}\; \rm N \cdot m^{2} \cdot C^{-2} \times 10^{-9}\; \rm C}{(3\; \rm m)^{2}} \\ &\approx 1.0\; \rm N \cdot C^{-1}\end{aligned}[/tex].

The direction of the electric field at a point is the same as the direction of a force from this field onto a positive point charge at this point.

Because the [tex](+1\; \rm nC)[/tex] point charge here is positive, the electric field of this charge would repel other positive point charges. Hence, the electric field around this [tex](+1\; \rm nC)\![/tex] point charge at any point in the field would point away from this charge.
