9. The tolerance is -+1 in the 3rd significant digit. Attached to each end of a thin steel rod of length 1.10 m and mass 7.10 kg is a small ball of mass 1.18 kg. The rod is constrained torotate in a horizontal plane about a vertical axis through its midpoint. At a certain instant, it is rotating at 31.0 rev/s. Because offriction, it slows to a stop in 27.0 s. Assuming a constant retarding torque due to friction, compute (a) the angular acceleration, (b) theretarding torque, (c) the total energy transferred from mechanical energy to thermal energy by friction, and (d) the number ofrevolutions rotated during the 27.0 s.(a) Number i(b) Number i(c) Number i(d) Number iUnitsUnitsUnitsUnits

The figure is a section of a conducting rod of radius R₁ = 1.20 mm and length L = 13.00 m inside a thin-walled coaxial conducting cylindrical shell of radius R2 = 11.1R₁ and the (same) length L. The net charge on the rod is Q₁ = +3.70 × 10-12 C; that on the shell is Q2 = -2.33Q1. What are the (a) magnitude E and (b) direction (radially inward or outward) of the electric field at radial distance r = 2.33R2? What are (c) E and (d) the direction at r = 5.07R₁?

In Figure (a), string 1 has a linear density of 2.08 g/m, and string 2 has a linear density of 4.84 g/m. They are under tension due to the hanging block of mass M = 677 g. Calculate the wave speed on (a) string 1 and (b) string 2. (Hint: When a string loops halfway around a pulley, it pulls on the pulley with a net force that is twice the tension in the string.) Next the block is divided into two blocks (with M, + M2 = M) and the apparatus is rearranged as shown in Figure (b). Find (c) M1 and (d) M2 such that the wave speeds in the two strings are equal. - String 1 String 2 Knot M (а) - String 1 String 2 M1 M2 (b)
