Explanation Given info: The mass of the metal rod is m and its length is d . The amount of current flow is I . The coefficient of kinetic friction between the rod and rails is μ . Formula to calculate the kinetic friction force acting on the rod is, f k = μ m g Here, m is the mass of the metal rod. g is the gravitational acceleration. Formula to calculate the force acting on the rod due to vertical magnetic field is, F = I d B Here, L is the length of the wire. B is the magnetic field. In order to move the rod at a constant speed, the kinetic friction force balances the force due to vertical magnetic field. Therefore, f k = F Here, f k is the kinetic friction force acting on the metal rod

Consider a single square loop of wire of area A carrying a current I in a uniform magnetic field of strength B. The field is pointing directly up the page in the plane of the page. The loop is oriented so that the plane of the loop is perpendicular to the plane of the page (this means that the normal vector for the loop is always in the plane of the page!). In the illustrations below the magnetic field is shown in red and the current through the current loop is shown in blue. The loop starts out in orientation (i) and rotates clockwise, through orientations (ii) through (viii) before returning to (i). (i) Ø I N - - I N - (iii) (iv) (v) (vii) (viii) a) [3 points] For each of the eight configurations, draw in the magnetic dipole moment vector μ of the current loop and indicate whether the torque on the dipole due to the magnetic field is clockwise (CW), counterclockwise (CCW), or zero. In which two orientations will the loop experience the maximum magnitude of torque? [Hint: Use the…

Please help with calculating the impusle, thanks! Having calculated the impact and rebound velocities of the ping pong ball and the tennis ball calculate the rebounding impulse: 1.Measure the weight of the balls and determine their mass. Tennis ball: 0.57 kg Ping Pong Ball: 0.00246 kg The impulse, I, is equal to the change in momentum, Pf-Pi. Note the sign change, i.e., going down is negative and up is positive. The unit for momentum is kg-m/s. The change is momentum, impulse, is often givens the equivalent unit of N-S, Newton-Second
