Homework 7 Mechanical work We learned that in order to change
... We learned that in order to change kinetic energy of an object we have to change the absolute value of its velocity (the speed). To do that we need acceleration and, hence, force (we know very well that there is no acceleration without force). But it is not enough just to apply force. We also know t ...

... We label single-particle states by 3 quantum numbers: l, the orbital angular momentum j, the total angular momentum = l ± ½ (since must add spin s = ½ )/ n, the nodal quantum number = 0, 1, 2, 3... We also can include label states by m (or jz) the 3rd component of ang. momentum. Single particle stat ...

... 2. If a moving space rocket is found to be 20% shorter than it would be when stationary, then how much slower will its clocks be running? 3. If you are travelling at 80% of the speed of light, passing objects seem to be only 60% of their normal length. This means that durations of passing events see ...

... 2. If a process has no Positive Work, then the sum of other three sections is constant equal to the previous box. 3. If a process has Positive Work in a position, this value is added to the KE as shown in Eq. (7c). Then the sum of other three sections is again constant , as in 2 above, for all follo ...
