For a particle confined to an infinite square well, is it correct to say that each state of definite energy is also a state of definite wavelength? is it also a state of definite momentum? explain. (hint: remember that momentum is a vector.)

Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

Africtionless piston-cylinder contains 50 l of saturated liquid r-134a. the piston has a mass and an area resulting in an applied pressure of 500 kpa on the refrigerant. the refrigerant is now heated until its temperature rises to 70∘c. calculate the work (in kj) done during this process.

Light traveling in a medium with a refractive index 1.19 is incident on a plate of another medium with index of refraction 1.79. at what angle of incidence is the reflected light fully polarized?
