I have had no problem while finding the eigen vectors for the x and y components of pauli matrix. However, while solving for the z- component, I got stuck. The eigen values are 1 and -1. While solving for the eigen vector corresponding to the eigen value 1 using (\sigma _z-\lambda I)X=0,
I got...
I think it will be very tiresome to pick each and every particle and work out their work done in bringing them from infinity to that position. There must be some quick method...

I have actually taken one particle pair at a time and sum all...
In forced vibration, amplitude of vibration changes periodically. Is it right ? I think it is a correct statement, since the amplitude of vibration is a periodic function.
In the spinning cylinder room example mentioned in relativity, where the nearest distance between 2 point is actually curved line.. and light take a straight pass right, which is farer than the curved line due to time dilation in the middle of the room due to a smaller acceleration than side of...
Since your position is changing, you are gaining potential energy and as you are pushing the bicycle, the potential energy comes from yours muscles, I mean -muscular energy
Bobby and Cindy are in different math classes. Bobby got a 75 on his test and Cindy got a 70 (surprisingly low for children of an architect). Bobby’s class had a mean of 80 and a standard deviation of 5. Cindy’s class had a mean of 75 and a standard deviation of 10. Who did better on their test...
Two waves of equal intensities "I" beat together, what is the maxima of the beat equal to ?
Is it 0 or infinity,or other answers... I just couldn't get it
