It affects the non-ideal properties of the transformer. Copper loss and stuff like that. When you model a non-ideal transformer you also consider the capacitance and inductance of wires, this will b affected by the gauge.

You sure it has multiple points and not just a voltage divider ?

So what does being equidistant have to do with it ? It'll have some some arbitrary expression for mutual inductance but transformer formula will still hold.

Aren't transformers with multiple tap points kinda expensive ? I would've thought its easier to use a voltage regular instead, such as puttin a variable capacitance in series with a fixed voltage.

Any magnetic metallic loop will do, specific shapes do not matter. You can very well wind coils one over the other.

In essence you need to couple two coils. You can do so by taking a metallic loop made of some magnetic material, and then wind wires on any two sides of this loop. Take count of number loops you wind to take care of voltage calculations. Also take out leads from both loops, one goes into your source and the other powers your bulb.

Is that really a good idea ? Hurricane ====> Run away !!

If x is the price in cents per litre, d the density in Kg/lt, H the heat of combustion in KJ/mol and M the molar mass in gms.......... [MATH]\frac{H_p*x_p*M_p}{d_p}=\frac{H_n*x_n*M_n}{d_n}[/MATH] The subscript p for petrol and n for LPG. ( I basically equated the price in cents/KJ) Plug in ther constants and given quntities to get your answer........

Can't work numericals in mind, will give you exact answer when I get home and get hold of a calculator.

What about average molar mass ? You'd need that !!

Without density you can't do anything !

To solve this you need to know the density of petrol and also the average molecular weight of petrol and LPG.

I agree it behaves as both (that actually goes even without saying, given that photons exhibit phenomena such as "exherting pressure") But light can generate matter (pair production) and matter can obviously convert to light.

No meaning just a reason : Elation at knowing that no other pulkit was around these parts, almost never get my real name as a user name anywhere else. Even the somewhat exclusive gmail won't lemme have it

The difference in time of posting #38 and #39 is just 6 minutes. While I was writing (and thinkin) it must've taken me over 6 minutes coz I definitely did not notice a post #38 back then

I am not referring to relativity here (I know nothing much about that) Atleast in cases where bodies are moving about at speed < 0.1 c , they should present little problem.

You simultaneously solve the eqution of the ellipse and the relavent side. Making sure that you use a form that is most convenient (parametric equation of elipse).

Upto a point it is alright to say that particles possess energy, but the problems leak in when they start converting themselves into energy. It almost makes me wonder if a way to look at it would be to think of matter as a condensed/stored/archived form of energy. Photons would then be an active interconvertable type of matter/energy.

The very essence of having a mating season , is to maximise the probability of survival of a new born. The fact is that humans have altered their own environments so much that, it really does not matter any more wether a child is born in june or in december. Then the very purpose of a mating season has been lost. Its probably that we were already a step ahead of the rest the animals, that we could alter our living environment so much that we no longer need a mating season and not the other way round.

The definition seems quite vague. I supose there can never be a clear distinction between matter and energy, photons might just be what bridges the gap in between them.

By limitation do you mean that animals can't explode their population exponentially ?? Given that they have smaller gestation periods and larger litter sizes that is still untrue.

An example at this point would be very apt.

Not trying to be elitist, if you ever did a course in advanced engineering level mechanics, its as simple as this : If you can't understand accelerated frames of reference or are not at ease with them, you probably will flunk your course. Of course it doesn't, its only a small part of physics.

If you come down to the definition of matter itself, what would you list as the common attributes of matter ? Wouldn't one of the attributes (intuitively atleast) be possession of mass ?

Simple procedure : Assume a temperature T, from that get the value of rate constant and equilibrium constant. Then you can arrive at an expression for concentration in which ammonia and water will form as a function of p alone. However, all this is again subject to the fact that you can somehow initiate the reaction and keep it going, spontaneity would intuitively require a very high temperature (to make free energy change just neagative). As free energy is directly linked to temperature by Gibbs-Helmholtz equation, the ideal way of achieving spontaneity would be to go on increasing temperature (endothermic reactions).
