No the radiated energy from a cell phone is far to weak to cause a spark to ignite a fuel.
You can't smoke in a petrol station because petrol especially has very volatile vapours. In theory petrol in the liquid where the air is controled will put out a flame which is beneth it. Petrol is at it's most dangerous in it's vapour and therefore smoking is a no no in petrol stations.
In the sense of a mobile communication: Downlink frequency is that used by a base station to communicate with the Mobile. In satellite communication also the same theory exists downlink is the return path.
The theory is that petrol is the result of decaying living beings; assuming this is so, the answer is yes: all living beings get their energy (directly or indirectly) from the Sun.
The plate tectonics.
The Theory, is what you think is gonna happen, for example, In Theory, a aeroplane could be given jet engines that run on High Octane Petrol( i don't know if that's true, its just a theory!) but we could try that and it could just crash, then our conclusion would be 'aeroplanes can not fly using High Octane Petrol, Aviation Fuel must be used' A Theory is an idea (Should be an educated idea, with reasoning behind it) and a conclusion is what your result is when you test that theory. Hope I helped.
Plate tectonics
Petroleum or crude is mixture of hydrocarbons formed by organic activities of dead plants and animals inside the earth (organic theory). Least accepted inorganic theory explains that the carbon deposits during formation of earth would have resulted in petroleum formation. When distilled,crude oil gives out petrol which is again hydrocarbon mixture..
There was once a theory, that electromagnetic waves might be used for communication over long distance. Your mobile phone is the proof that the theory was correct.
In theory yes but there's very little point in it as you can either get ethanol from crude oil through distilling and cracking through which you can also get diesel and petrol from. You can also make ethanol out of vegetables but again you can also make diesel. The main use of ethanol in running cars I would say is bio-petrol which is just a mixture of petrol and ethanol. All this achieves is less petrol being used. But yes, you can fuel your car on it after modifications but it's more commonly used as an additive to petrol.
It is the theory of establishing three dimonsional positions of an area/field/ with respect to a known direction and known level. It is a very good application of trignometry.
In theory - it could be anywhere ! It looks like a mobile number but it could belong to any country.
In theory an air jack could be used, but hydraulic jacks are standard for setting mobile homes. Two 12 ton bottle jacks are usually sufficient for the job.
