The yellow light from a helium discharge tube has a wavelength of 587.5 nm. When this light illuminates a certain diffraction grating it produces a first-order principal maximum at an angle of 1.150 degrees.
Calculate the number of lines per centimeter on the grating.
Calculate the x-component of vector. A uniform electric field of magnitude 375 N/C pointing in the positive x-direction acts on an electron, which is initially at rest.
A 1050kg car carrying four 78kg people travels over a rough "washboard" dirt road with corrugations 4m apart which causes car to bounce on its spring suspension.
A particle of mass M decays into two identical particles each of mass m, where m = 0.4M. Prior to the decay, the particle of mass M has a total energy of 4 Mc2 in the laboratory reference frame. The velocities of decay product are along the directi..
