There is science fair competition, and I have decided to participate in it with my friend by making an "Semi-Ion drone". It is semi-ion because i am thinking of using an compressor to compress the air and then ionise(am i spelling this correct?) it, which i believe should provide more acceleration since more air particles are being ionised? Am I correct with my thoery? Also, I guess since there is a need of 20 kV, does it mean it's energy requirement is huge?

OMG, such a wonderful teacher.

Sorry, poor choice of words, I mean "store energy" This was the exact answer I was looking for, "how will it stop?". Thanks a lot @Janus This is because of the heat produced during the process of energy conversion(from kinetic to electric and then light), right? does it mean earth will stop rotating (maybe after 10-12 billions years?) is that app "Chemistry Lab Guru" yours? I mean developed by your colleagues? It's quite impressive.

Yes I do know but how, especially in this case? There so contact between the flywheel and literally anything that might cause friction, so how?

I heard about fly wheel battery systems and after reading a bunch of articles and watching some videos about it I have an Idea. Basically the fly wheel looses it's rotational energy only due to friction(or am i wrong?), so if I we are able to eliminate all the friction forces by taking it to space where it won't take much energy to elevate it with magnets and also by creating vacuum, will I be able to create unlimited energy since the wheel will keep spinning for ever(or at least for drastically longer period than the current ones)?

As @swasnot said, But in case of Gravity, it's not possible to make gravitational force 0 when speaking mathematically. They can be made negligible but not 0 as that would need you to take the object to an infinite distance. Hope it helps you

Thanks to everyone. See you all soon

Actually we are talking about why magnetic field are not induced in covalent bonds. I am sorry friends, I think I lost it from here. It's not your explanation, it's just my weak grasp in chemistry, I am trying my best to improve. But alot of thanks for your effort. Will take my teacher's help in this.

Ooh, now I got it. But what about exception like graphite?

Friends, I think I didn't framed my question well enough(I was worried weather I explained it nicely or not). What I wanted to ask was that, after I complete the complete syllabus for 12th standard. Then what? How can I study university level topics(if that's what you call it).

This question isn't specific to classical physics only or even to this particular subject. Actually the question is how can I learn more than what school is going to teach me. Since the schools teach really slowly and I even prefer to learn by my self for 2 reasons that, I can study "anytime" and for as long as I want to. No doubt schools are good, but it's the fact that they can't match the feel of self learning. So when I complete all the topics mentioned in NCERT books(They are the basic and compulsory books for high school), then what? How will I know what I have to learn next? Please guide me Thanks

I request elaboration for this specific statement.

Since the shared electron in the covalent bond oscillates from one atom to another, its should change the magnetic fields around it and hence result in formation of electricity. But why it doesn't happen?

How come newton's laws of dynamics apply on sub-atomic scale?

Well they are over here India, we have been taught about the pattern of magnetic field line in a solenoid, electromagnetic induction and Faraday's Law. So does this mean that, the rate of increase of Voltage is higher than the increase in resistance so the current also increases to keep the equation V = I*R true. Right? What if instead of solenoid I decided to use a torus. Wouldn't that be great? Torus is a kind of solenoid with infinite amount of turns, and a copper torus would give maximum possible voltage.

I have seen and been told that the voltage increases in a solenoid with more number of turns. Why does the voltage increase, and what is the point of doing this because the current should remain the same since resistance is increasing at the same time and that would balance the equation V = I*R. Right?

Thank you guys, appreciate your efforts.

I'm really sorry to you all, I only watched half the video. Here is the link: In the end he tells that all this is fake and he has been hiding his tesla coil under the table. Really sorry for wasting your time. Sorry @studiot @Intoscience and @iNow

It's clear that equilateral triangles are not included, because they are isosceles since the requirement of and isosceles triangle is that there should be atleast 2 equal sides and 2 equal corresponding angles which an equilateral triangles satisfies

You sounded like a dad trying to teach his 10 year old son mathematics. Lol Well in that way we can draw a perpendicular from from A and the Root of the Tree in such a way that we get 2 right triangles sharing the same hypotenuse. Then by some pythagorean tricks and some trigonometry find the answer.

Well the script is pretty simple for this, try reaching out someone who have some experience in this (it can be any language, python c c++ c# or any). He/She would do the job in no time.

So, It's the chemical substance that reacts to magnetic field. right? If so, isn't It a good idea to use this method. As fluorescent blubs are pretty common in public as well as homes. Won't this advantage the user economically and help save the environment at the same time?

Well I have heard about voltage without current but not sure how it is possible, and current without voltage shouldn't be possible. Can you explain both situation in depth (by depth I don't mean 10 paras, that would be inconvenient for you)? or you can just tell me about an article or book itself where I can learn about it.

I saw a video on YouTube where a person holds a bulb between 2 medium sized magnets, the bulb starts glowing. Neither the bulb is moving nor the magnets, then how the current is generated?

This is the missing piece I was looking for, this completes my answer. Thanks a lot swansnot, studiot, zapatos and exchemist. Thanks a lot again.
