Please answer these questions, I would like it if it's not too detailed yet not too easy. Questions: What gases are used in a light bulb?What instrument do we use to measure current? What units do we use when we measure current?Describe the working of a doorbell.What are Maglev trains? How do they run?What effect does electric current have on chemicals?Where describe is written, please make it a bit detailed. Thank you very much and yes it is a big urgent.

Please DIGITABLE! LETTER BY HAND GETS UNDERSTANDING.

#29 The correct answer is already highlighted, explain in a very simple way why that is the correct answer. Briefly discuss its concept & provide an illustrative example.

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.

please answer the questions in terms of electric car
