A photon emitted as a hydrogen atom undergoes a transition from the n = 5 state to the n = 2 state. The energy of the ground state is 13.6 eV.
Find the wavelength of the emitted photon. The speed of light is 3 × 10^8m/s and Planck's constant is 6.626 × 10^?34J · s.
Find the frequency of the emitted photon.
A penny of mass 3.10 g rests on a small 22.40 g block supported by a spinning disk of radius 11 cm. The coefficients of friction between block and disk are 0.715 (static) and 0.64 (kinetic) while those for the penny and block are 0.564 (static) an..
