Reference no: EM1346203

Q.A 1,000.0 kg car with a speed of 90.0 km/h brakes to a stop> How many cal of heat are generated by the brakes as a result.

Q. A charge of 3.80 10-6 C is placed on a small conducting sphere that is located at the end of a thin insulating rod whose length is 0.22 m. The rod rotates with an angular speed of ω = 156 rad/s about an axis that passes perpendicularly through its other end. Find the magnetic moment of the rotating charge. (Hint: The charge travels around a circle in a time equal to the period of the motion.)
