: A particle of mass m in an infinite square well of width a starts out in an equal superposition of the ground state and the 2nd excited state. (a) Write down Y(x, 0) (properly normalized) in terms of a, m and the relevant constants.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
