Let's suppose i confine the particle i'm interested in to x values between zero and some distance a. (meaning that the particle must exist somewhere between 0 and a.) find the normalization factor and write out the normalized wavefunctionf for: (x) = sin(); where a is a constant note: totally fine with me if you use something like wolframalpha to evaluate this, but if you do, screenshot your input and result to submit to me. calculate an expectation value 6. calculate the expectation value of linear momentum (x-component) for a free particle, y(x) = el.

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
