A force is applied to the rim of a disk that can rotate like a merry-go-round, so as to change its angular velocity. Its initial and final angular velocities, respectively, for four situations are:(a) -3 rad/s, 7 rad/s; (b) 3 rad/s, 7 rad/s; (c) -3 rad/s, -7rad/s; (d) 3 rad/s, -7 rad/s. Rank the situations according to thework done by the torque due to the force, greatest first (use onlythe symbols > or =, for example, a>d=b>c).
