The rotor in a certain electric motor is a flat, rectangular coil with 83 turns of wire and dimensions 2.57 cm by 3.84 cm. The rotor rotates in a uniform magnetic field of 0.800 T. When the plane of the rotor is perpendicular to the direction of the magnetic field, the rotor carries a current of 10.3 mA. In this orientation, the magnetic moment of the rotor is directed opposite the magnetic field. The rotor then turns through one-half revolution. This process is repeated to cause the rotor to turn steadily at an angular speed of 3.54 X 10^3 rev/min. (a) Find the maximum torque acting on the rotor. N · m
(b) Find the peak power output of the motor. W
(c) Determine the amount of work performed by the magnetic field on the rotor in every full revolution. J
(d) What is the average power of the motor? W

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
