When a light bulb shines, it gives off light energy and energy. a. heat b. potential c. chemical d. electrical

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].

Efficiency is the ratio of to for a system a)power in to power in b)power in to power out c) power out to power out d) power out to power in
