Sixteen motes (miniature low-cost processors with built-in sensors) are being used to monitor the average temperature of a furnace. each mote has limited communication ability and can communicate with two other motes only. the wireless network of motes is not partitioned. find out how each mote can determine the average temperature of the furnace

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
