A6.0-cm-diameter disk emits light uniformly from its surface. 20 cm from this disk, along its axis, is an 7.0-cm-diameter opaque black disk; the faces of the two disks are parallel. 20 cm beyond the black disk is a white viewing screen. the lighted disk illuminates the screen, but there’s a shadow in the center due to the black disk. what is the diameter of the completely dark part of this shadow?

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].
