The correct statement about the relation between the shear stress (force) at the surface for laminar and turbulent flow over a flat plate is. a. The laminar shear stress is greater because the fluid viscosity is not important in turbulent flow. b. The turbulent shear stress is greater because the mixing dissipates more energy, producing a greater stress at the wall. c. The laminar and turbulent shear stresses are equal at the same position (x) along the plate, but since turbulence occurs farther down the plate it produces a higher shear stress. d. The laminar shear stress is less because the boundary is thinner in the laminar regime.

One of my tools stopped working, and I found that in order to fix it, I need to replace a broken wire. The broken wire has a diameter of 5mm and a length of 15 cm. When it was connected to the battery, a current of 12.5mA flowed through the wire. The only wire that I have at home is the same material, but has a diameter of 2mm.

a) If I replace the broken piece of wire with a 15cm length of my 2mm diameter wire, what will happen to the current (increase or decrease) ?

What is the value of the current through the new wire (assume that it's connected to the same battery as the original wire) ? Hint: Think about the resistances of the old and new wires.

b) How long should the new wire (2mm diameter) be if I want to ensure that the current passing through it is the same as the original wire (12.5mA) ?
