Just as a skydiver steps out of a helicopter, someone who’s watching starts a stopwatch. So the time is zero as the skydiver steps out of the plane. What is the skydiver downward velocity at that instant just before starting to fall?

Consider two metallic rods mounted on insulated supports. one is neutral, the other positively charged. you bring the two rods close to each, but without contact, and briefly ground the the neutral rod by touching it with your hand. show answer correct answer what would be resulting charge (if any) on the initially neutral rod

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

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].
