Consider a circular current loop in the ay plane, with radius a, centered at the origin, and carrying current i. on the z axis the magnetic field has the form b: (z) determine b, (z) and evaluate ft o b, c)dz. by ampère's law, the integral must be μ。. why?

One form of energy can be another type of energy. a. created to form b. transformed into c. destroyed and then created to form

A0.580-kg rock is tied to the end of a string and is swung in a circle with a radius of 0.500 meters. the velocity of the rock is 4.50 m/s. what is the centripetal force acting on the rock? 15.5 n 5.22 n 69.8 n 23.5 n

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].
