Guys, Hello, I am a high school student who has just started basic calculus and would like to know how to find the motion of the projectile taking air resistance into account. (The range, time, etc)(I have learned about projectile motion without air resistance) Please help me.

If the base current of an NPN transistor is increased, what will happen to its Collector current since I still don't understand how a transistor amplifies signals or about the current gain. (i.e. Ic/Ib)

What does a capacitor actually do? Does it store electrical energy or does is store charge? Please Explain.

I was wondering; if a water is say at a temperature of 50 Celsius and we put two thermometers into it, one which is a mercury in glass and the other which is of alcohol (same mass of both constituents); when we break the thermometers directly after the readings are stabled and we measure what...

Well let me get this straight. Is the theory of special relativity true? I mean can mass be changed just by changing its speed close to the speed of light?

It seems that what you are saying about the flaw in Einstein's theory, is wrong. You can't say that if two objects are traveling at the same speed, it would seem that the total speed is the addition of both speeds. after all they are two different bodies and though momentum might be same but the...

I was wondering if anyone could tell me whether a body traveling at a velocity close to the speed of light would have the same mass as its rest mass since Einstein's theory of special relativity says that: M0=M1/Underroot1-(Beta)2 Where M0=Rest Mass and M1=Mass at that speed

So are you saying that to take the 1 coulomb charge, the energy required depends on the displacement of the charge? (Distance traveled)

Hey please answer

Of course, I mean, the minimum energy required would be same. It only depends on you later how much energy would you apply. The thing is, the minimum energy required is same.

Hey but then in either ways, the charge that will be carried will be of 1 coulomb right, then how can it be that for only one coulomb charge, there will be different amounts of energy needed to carry it? (since it is constant) I mean on what basis does the energy needed to take one coulomb...

Hey every one, can you please tell me what potential difference is. Is it the amount of work needed to bring one coulomb charge from a point to another or is it the amount of work done to bring one coulomb charge from a point to another.
