A proton of mass ,mp, (given in data) is confined in a very-deep Square-well potential with L= 1 femto meter.
(I) Sketch a diagram to show the allowed energy levels of the proton inside the well.
(ii) Estimate ground-state energy of the proton.
(iii) If the proton somehow gets excited to n= 3 level and then jumps back to n=1 determine the energy and wavelength of the emitted gamma-ray photon.
A person can survive a feet-first impact at the speed of about 12 m/s (27 mi/h) on concrete; 15 m/s (34 mi/h) on soil; and 34 m/s (76 mi/h) on water. Why are there different values for different surfaces.
The density of gas atoms at a certain location in the space above our planet is about 4.00 x 1011/m3, and the pressure is 9.50 x 10-10 N/m2. What is the temperature there?
In the annual battle of the dorms, students gather on the roofs of Jackson and Walton dorms to launch water balloons at each other with slingshots, Find the direction of the balloon's inital velocity
Find how the curvature radius R of the point's trajectory and the total acceleration w depend on the distance covered s.
A uniform stick d = 1 m long with a total mass of 251 g is suspended vertically from a frictionless pivot at its top end. A wad of putty of mass 20 g is moving horizontally with speed v. It strikes and sticks to the stick at a distance 0.75 m from..
