1. ## A question about Quantum mechanics

Do you mean that there are other ways of interpreting it?
2. ## A question about Quantum mechanics

I think this is the problem with quantum mechanics and string theory. Although I beleive that the String theory is correct, many people say that it cannot be proven (and may never will be) by experiment, and therefore, it is not a science, but a philosophy!
3. ## Sorry for the noob question... Magnets-energy?

No, unless the magnet has been given the potential energy to give out that energy, it is not possible. This is the main flaw in most perpetual machines. Many people see that a magnet is a source of energy, which it isn't. A magnet, you can think of it, is a way of storing energy, like a battery. This is done by pulling the metal object stuck to it away from it, like a spring!
4. ## Recoilless Railgun?

Well, if you are talking theoretically, as long as both the projectiles are moving exactly opposite to each other and in exactly the same speed (they should also have the same mass), yes, it will neutralise the recoil. However, you can also vary the mass of the projectile that is going in the opposite direction. The bigger the mass, the slower it shoots out the other end, given that the original projectile moves at exactly the same speed. So, theoretically speaking... yes!
5. ## The master set of equations

Hi guys! From what I understand about the string theory: It is a theory that is trying to unifry the four fundamental forces of nature (electromagnetism, gravity, the weak force, and the strong force). The string theory tries to create a set of master equations that will unifry all those four forces. My question is, what will the equations actually tell us? What will they calculate?
6. ## Saturated Solution

Salt:35.9 g/100 cm^3 (25 °C) Sucrose: 1 g sucrose in 1 g water (at 25 °C) According to a quick google search!
7. ## Sorry for the noob question... Magnets-energy?

The potential energy that you give it either comes from the big bang (as I stated earlier) or if the object and the magnet were already stuck together, the energy comes from splitting them apart

Please allow me to add to that: f(x)= the normal function f(x+a)= is a shift in the left direction (ie the graph moves towards the leftof the graph) It works the opposite of what you might think f(x)+a= the graph moves upwards, exactly what you might think
9. ## Saturated Solution

Wow! Thanks alot for that!
10. ## A question about Quantum mechanics

So basically, if there are 10 possible outcomes, the particle is in a superposition of all 10 outcomes?
11. ## Saturated Solution

Just a quick question, although it may be highly unlikely: Supposing you have a substance that has exactly the same solubility of salt and you have that saturated salt solution. If the substance was added to the solution, would the subtance dissolve? I think that it won't, but I'm not sure!

1.I would think that assymptotes are formed where there are no values of y which can be produced when x is a certain number. A very common assymptote is 1/x where y cannot be found when x=0. This is, probably, how you would need to modify the equation. 2.As for your second question, I really don't understand what you mean by "What would you have to do to adjust where along the x-axis this asymptote intersected?", especially the 'intersected' part. Hope this helps!
13. ## A question about Quantum mechanics

Sorry Swansont, but I cannot really understand what you mean by a "superposition of states". Could you please explain to me what that means?
14. ## A question about Quantum mechanics

Is this related to my post?
15. ## A question about Quantum mechanics

So, isn't the event of what I have mentioned quantum mechanics, since there will be a probability of 10 things happening? Or is it just the science of probability?
16. ## Sorry for the noob question... Magnets-energy?

Well, its more complicated than it sounds, and no, its not a noob question. When you place a magnet near a needle, for example, the needle moves towards the magnet. Therefore, you would think, it does work, and it does. The magnet contains potential energy,which may have come from the big bang that goes into splitting the atoms of this needle and the magnet. When you make a magnet attract a needle, you are unleashing all this potential energy. So, yes, it can be used to do work, as long as you give it the energy. But the magnet does not make its own energy, and therefore, can't be used in perpetual motion (which is where I think this topic is coming to )
17. ## A question about Quantum mechanics

Sorry if I sound a little stupid, but you said that it was not quantum mechanics. Isn't it? Because there is a probability of something happening? I'm fairly new to the subject, so, please, simplify the explanations down to my level!
18. ## A question about Quantum mechanics

Hi guys! Sorry I haven't been participating a lot lately. This is because I just finished my As levels and movedo on to do A levels. AT the start of the year, the first physics topic we are doing is about waves and our universe. We watched quite a lot of videos on the string theory and quantum mechanics. The question about quantum mechanics is: From what I have understood, quantum mechanics states that if there is a probability of, let's say, 10 things happening, then ALL 10 things will happen. MY question: Where do they happen? Do they happen in parallel universes? Please make your language simple and have mercy on me I only just started doing this stuff, and we have only touched upon it very briefly, so my knowledge isn't really that high! Thanks!
19. ## SI Units

Ok, I got that now! Thanks!
20. ## SI Units

But, isn't radians used in cacluations and formulae, and therefore a base unit? You can't have anything replacing a measure of angle to give the correct answer. Therefore, I would think that, even though it is a ratio, it is also an SI unit.
21. ## Combustion of 1,2 chloro propane

Thanks alot for your help guys. Nice bit of information provided by YT! Thanks!
22. ## SI Units

Okay. Thanks for that!
23. ## Combustion of 1,2 chloro propane

Ok, I thought the acid prduced was hydrogen chlorate (HClO3). Is that a possibility, since you hace plenty of oxygen for the reaction to occur?
24. ## Combustion of 1,2 chloro propane

Hi guys! In my chemistry course, we learnt different reactions of halogenoalkanes, such as substitution reactions, and elmination reactions. One of the reactions that came up was a combustion reaction. What are the products of teh reaction if the substance is burnt completely in air. I know that water and carbon dioxide are produced, but what happens to the chlorine, or the halogen that is attatched to the chain? I did a quick lab test, in which I used litmus paper, and there was certainly an acid produced. But which one? Thanks alot for your help!
25. ## SI Units

Hi guys! Its been a long time since I've been here. I've been busy with my AS, and arranging a further maths course for me for my A level! Here is my question: In physics, we were taught that there were 6 (which we were then told 7) SI units, which are: m=meters s=seconds K=Kelvin kg=Kilograms mol=moles A=amps and later : cd=candela (a measure for luminocity) My question is: What about measure of angle? We can't use any of the SI units above to shop an angle, which is quite important in mechanics (the physics course where we were taught this). Thanks alot for your help guys!
