Answer:
Power supplied to the pump is 980000 W or 980 KW
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
The north pole of a magnet is brought near to the current-carrying solenoid.
State whether the north pole is attracted or repelled by the solenoid. Explain why.
Answer:
The north and south pole of a solenoid depends on two factors. One, the direction of the current flow and two, the direction of the winding (clockwise or counter-clockwise). ... If clockwise in relation to the positive wire then is the south pole, if anti-clockwise then is the north pole.

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.
Answer:
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.
