help!
how do we solve a mixing problem involving 3 inlet pipes and 2 outlet pipes?is it okay to just add up the 3 rates of input as well as their respective concentrations?
all the sample problems i have encountered involves only 1 inlet and one outlet pipe..
Hey guys, please help me about this topic:
What are the applications of LRC circuits (Inductor-Resistor-Capacitor circuit)?
I've searched many sites but I haven't found any applications and explanation on how these applications work using LRC circuits. I've also read the books that are...
"There are many reasons for including hydrogen among the elements in Group IA. It forms compounds (such as HCl and HNO3) that are analogs of alkali metal compounds (such as NaCl and KNO3). Under conditions of very high pressure, it has the properties of a metal. (It has been argued, for example...
what is hydrogen?? a metal or nonmetal?
there are times/characteristics wherein hydrogen could be classified as a metal and times where it could be a nonmetal, even a metalloid..
so what is hydrogen??
anybody knows the answer??help me pls.. :frown:
hey tide,
ideal voltmeters should have infinite resistance so as not to alter current but real voltmeters have finite resistance.does our voltmeter, in any way, still alter the current flowing through our set-up?
how would the ammeter resistance affect the total current when the instrument is inserted in the circuit to measure the current? does this give you an idea about the desirable design of ammeters? why?...thanks for helping :smile:
in measuring unknown emf by potentiometer, why must the stable current source(working battery) have a voltage greater than any voltage to be measured?
i can't understand why..
in our exercise in physics, we used a slide-wire potentiometer with the assumption that 1 meter of the slide-wire...
