A particle is projected on a frictionless surface in their direction at a speed of v = 10 m/s. It bounces off of a moving block that's moving at a constant speed of = 5 m/s. The coefficient of restitution between theparticle and block is e = 0.84. Solve for θ, neglectinggravity. Specify your answer in degrees.
The isotope shift of spectral lines refers to the shift in wave- lengths (or frequencies) due to the different masses of given ele- ments. Find the isotope shifts for each of the four visible Balmer series wavelengths for deuterium and tritium compar..
