Copy of PHY12 - Lab 3 Self Assessment

I want the solution printed (not handwritten) and the drawing, if any, I want it in a professional way, thank you for cooperation

can you answer these questions on solar thermal collector experiment using the following bullet points. Why does correct positioning and weather affect the results obtained? Why it worked/failed. In your opinion, is Solar Thermal a useful technology for the UK? Avoid giving a binary answer and try to think of all variations of solar thermal technology and all regions of the UK. How would you modify the technology to become better/more efficient and more appropriate for the UK? If you were given the chance to do the experiment again, how would you do it and why? The answers to these questions should be supported by mindful arguments. This should occupy, at least, two pages of the report.

1. Which of the following statements accurately describe the "Data" section of a lab report? O It shows charts and graphs that can help people visualize results. O It explains the research other scientists have already done. OIt contains the raw measurements taken during the experiment. It discusses the meaning of the results of the experiment.

The answer in the following image are wrong, so provide your work in. a written format, if you provide in typed format or provide the same answers as shown in the image your answer will be downvoted. A patient takes 250 mg of a drug at the same time every day. Just before each tablet is taken, 5% of the drug remains in the body. (a) What quantity (in mg) of the drug is in the body after the third tablet? After the nth tablet? third tablet 263.125 ✓ mg nth tablet 263.157(1-0.05¹) X mg (b) What quantity (in mg) of the drug remains in the body in the long run? (Round your answer to three decimal places.) 263.157 X mg

Why there is a different between measured and calculated value? Give 3 reasons Why errors exist during the experiment? What would happen to the percentage of relative error by varying the values of R1?.

1. Answer the subparts A&B with the step, based on the Image. This question Q&A please no reject and solve thank u A) Based on the measurement data above, indicate that there is an error in the measurement      data. Give an explanation of the answers given. B) Determine in which element there is an error in the measurement data. What should be       the correct measurement result. Give an explanation of the answers given.

Lighting consumes 4% of the energy consumed by a building. Control strategies that turn lights on when the space is occupied are one energy savings strategy. In this problem, we'll calculate the energy impact of a lighting schedule. For the purposes of this problem, a neopixel is a single LED. A neopixel strip is a group of LEDs. A) Measure the current draw of your neopixel strip of 5 LEDs when all 5 lights are powered on, set to full brightness, with each RGB color set to 255. Report your answer in units of amps. B) Calculate the power consumption of your 5 neopixel strip when connected to a 5V source using the current measured in part A. Report your answer in units Watts. C) Imagine neopixels are used to light the entire engineering building, which requires 50,000 neopixels. Calculate the energy consumption due to lighting of the entire engineering building for one 7-day week assuming: i. Option 1: Lighting is on continuously for 7 days ii. Option 2: Lighting follows a schedule:…

A professor teaches two sections of a course: • 70% of students are in Section 1, and 30% are in Section 2. • In Section 1, 90% of students pass the final exam. • In Section 2, 80% of students pass the final exam. A student is randomly selected. a) Draw a tree diagram to represent this situation. b) What is the probability that the selected student passes the exam? c) Given that a student failed, what is the probability they were from Section 1?
