5. What force is needed to pull one microscope slide over another at a speed of 1.00 cm/s, if there is a 0.500-mm-thick layer of 20 degrees C water between them and the contact area is 8.50 cm^2?
62. (a) Calculate the retarding force due to the viscosity of the air layer between a cart and a level air track given the following information-air temperature is 20° C, the cart is moving at 0.400 m/s, its surface area is 2.50 x 10-2m², and the thickness of the air layer is 6.00 x 10-5m. (b) What is the ratio of this force to the weight of the 0.300-kg cart? 63. What force is needed to pull one microscope slide...
64. A glucose solution being administered with an IV has a flow rate of. What will the new flow rate be if the glucose ist.Peshaced by whole blood having the same density but a viscosity 2.50 times that of the glucose? All other factors remain constant. 65. The pressure drop along a length of artery is 100 Pa, the radius is 10 mm, and the flow is laminar. The average speed of the blood is 15 mm/s. (a) What is...
