This particular capacitor is made from two strips of aluminum foil separated by a strip of paraffin-coated paper. Each strip of foil and paper is 6.60 cm wide. The foil is 0.005 00 mm thick, and the paper is 0.030 0 mm thick and has a dielectric c
The coefficients of friction for plastic on wood are μs = 0.50 and μk = 0.40. How much horizontal force would you need to apply to a 3.0-lb plastic calculator to start it moving from rest.
Assume that the net horizontal force is due to rolling friction only and take the free-fall acceleration to be g = 9.80 m/s^2. What is the coefficient of rolling friction mu_r for the tire under low pressure?
