A movable plate is at a height 0.05 mm above a fixed plate. The separation between the plates is filled with a fluid. The top layer of the fluid moves at a speed of 100 cm s 1 (thus, the moyable plate moves at this same speed). A force of 2 N per unit area is required to maintain this speed. Assuming the flow of the fluid is laminar and the change in velocity of the fluid is constant, determine the coefficient of viscosity of the fluid.

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
