A hydrogen atom in a state having a binding energy (the energy required to remove an electron) of 0.544 eV makes a transition to a state with anexcitation energy (the difference between the energy of the state and that of the ground state) of 12.750 eV. What is the energy of the photon emitted as a result of the transition? Use -13.60 eV as the binding energy of an electron in the ground state.
A 47 kg skier starts from rest at height H = 19 m above the end of a ski-jump ramp as shown. as theskier leaves the ramp, his velocity makes an angle theta= 29 above the horizontal. neglect air resistance and friction. calculate the speed of the s..
