Oh I get what you guys mean. I was interpretting the statements wrongly. K, thanks for the help. It's really appreciated.

From the equation, do you mean that frequency is proportional to the energy of a type of light (like infrared of ultraviolet) while wavelength is inversely proportional so the statements that 'When solids are heated, they emit electromagnetic radiation over a wide range of wavelengths. The...

Thanks for the help, but how can I relate that to the question? What I mean is that the two earlier equations are contradictory since one says that the energy of wave depends in its frequency while the other says that the amount of energy of the wave depends on its wavelength. Which of these is...

Hi guys, I was reading through some Chemistry papers when I came across these two lines; When solids are heated, they emit electromagnetic radiation over a wide range of wavelengths. The amount of radiation energy emitted by an object at a certain temperature depends on its wavelength. However...

Sorry there. I was really busy this past week. I think rl.bhat is correct though. Rlly sry again.

I'm quite sure that u just have to take (net force acting on m1/SUB]) / m1 to find its acceleration. Since taking that m1 is accelerating downwards instead of upwards, find the gravitaitonal force acting on m1 and minus the force acting on m2 + m[SUB]3 and you will get the net force.

Ok, so from the diagram I can see that the three resistors have different current passing through them but have the same voltage difference so the MUST be parallel, right? Is this method standard for all examples? Thanks for the help.

Hey guys, I'm having a little troublt with rearranging resistors in a circuit to identify which are parallel and which are in series so I can decide how they should be added; RTotal = R1 + R2 or RTotal = 1/R1 + 1/R2. Taking that each of the three resistors in the circuit shown (diagram...

Oops, sorry for the late reply. Kinda got caught up in sme work. K, thnks for the help in understanding the definition of voltage and all.

Ok, so the voltage is something like the unit of measurement for potential so it can't be used up. I see. K, thanks for the all the help. It's really helped me understand electric current better. Thanks.

Oh, I see so just to be clear, current is the amount of charge between a certain region per second. A resistor in a circuit will maintain the amount of charge/second throughout the circuit but the voltage will decrease as some work is done because of the resistor. Am I right?

Thanks for the help, but if we use water as an analogy like you said, won't the speed of water decrease as it moves through a constriction like a resistor for electricity? Won't the speed of water be lesser after it moves through the constriction apart from the pressure(voltage) decrease?

Hi guys, I'm currently doing current electricity but I'm not rlly sure why current is always the same throughout a circuit, even with resistors. I've searched sites such as Wikipedia, which states that If this is so, shouldn't the current be lesser after it passes through a resistor? Any help...

There are two test tubes with a piece of iron soaked in water in each of them. One piece of iron has a coating of zinc while the other has a coating of copper. The question is that in which test tube is the iron least likely to rust and the answer key states that it is the piece of iron with the...

K, thnks for all the help. I get it now.
