The energy of a photon was found to be
3.38 × 10–19 J. Planck’s constant is 6.63 × 10–34 J • s.

Which color of light corresponds to this photon?

The Answer is green

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
