Hi,
Suppose that I am holding a pen in my hand and then i move my hand in such a way that the pen starts revolving around my index finger. It rotates in such a way that it seems that my finger is the center of the circular path(the path, through which the pen is revovling)...
Hi
When we fill a tumbler( of stainless steel) with water and then invert it ie empty it . The tumbler gets empty except a few drops of water. even if you keep the tumbler inverted for hours the water droplets do not fall down they remain stuck to the walls of the tumbler.
I hope you...
Hi
Please forgive me if i am wrong but i think this equation tells us that greater the displacement of an object in space coordinates the lesser its displacement in time coordinates eg: If an object moves at a velocity close to light than time will move slowly for that object.
Hi chris
I am from India and i don't boast that i have understood everything but yes many of the parts you explained were very lucid and easy to understand.
Hi
you are wrong for nothing exceeds the speed of light. You might be saying the above for the only reason that you might have a read an article saying that some experiments of NASA show that universe has expanded on all the sides by a great rate and they also think that the expansion of the...

A short but clear explanation
Hi
The photons can only eject electrons when the frequency is greater than the work function. we know that the energy of the photon would be equal to hf. For eg if hf=phi than f is known as the threshold frequency here phi means the workfunction,now if hf>phi...
Hi
Thankyou but then suppose that we have a single player and he just starts hitting the shuttle cock vertically in this case the shuttle cock travels vertical distance and then at the highest point it changes it behaves strangely ie in the beggining the cock faces us and and then it does...

If i was from the awards commission than i would have surely giveen you the physics guru award for 2007. A great post . I have just completed my 10th grade but still i can understand it
cool:rolleyes:
Quite a funny question
Now when we hit a shuttle cock by racket or any other means, the shuttle cock moves in the direction of the force but halfway the position of the shuttlecock changes ie in the beggning the cock faces us and then at halfway the cock starts facing the opposite...
