Considering massive particle with K is a constant specifying the spatial curvature =0 would the dependence of a (t) scale factor of energy and momentum still holds? k is a constant specifying the spatial curvature and a(t) is the scalefactor

A neutron of mass m of energy E a,V(x) = Vo ) II. Estimate the kinetic energy of the neutron when they reach region III.

Consider a particle of mass m confined in a three-dimensional cube of length L so small that the motion of the particle is relativistic. Obtain an expression for the allowable energies of the particle in this case. Calculate the ground state energy for an electron if L = 10 fm (10 ^ -5 nm, a typical nuclear dimension)

A 4.90g Particle confined to a box of length L has a speed of 4.70mm/s a) lalhat is the classical Kinetic energy of Particle? the b) If the energy of the first excited State (n=2) is equal to the Kinetic energy found in part (a), what is the value Note: Answer must be in mi L? of c) Is the result found in part (b) realistic ? Explain.
