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).

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?

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
5. Three blocks, each with mass m, are connected by strings and are pulled to the right along the surface
of a frictionless table with a constant force of magnitude F. The tensions in the strings connecting the
masses are T1 and T2 as shown.
