Atop plate is moving over a second fixed plate to the right with a constant velocity of u=3 ms. the gap between the two plates is h=6mm and is filled with a fluid of dynamic viscosity p. ssx.10 pas. a 1) assuming linear velocity distribution, calculate the shear stress on the upper and bottom plates. 2) assume a nonlinear velocity of the form v 6.99+0.873 in y where y is the distance from the bottom fixed plate. calculate the shear stress for y 3 mm.

At the negative terminal of the battery the electron has electric potential energy. what happens to this energy as the electron jumps from the negative to the positive terminal?

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.
