What is the magnitude of the force a 2.5 x 10^-7 C charge exerts on a 4.2 x 5 points 10^-5 C charge located 1.8 m away?

Aria drove to the store, did some shopping, and then came home. during maria's trip, when was her displacement equal to zero?

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

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].
