Q1. A horizontal pipe contains water at a pressure of 150 {rm kPa} flowing with a speed of 1.6 {rm m/s}. The pipe narrows to one-half its original diameter.

Q2. A long wire lying along the x-axis carries a current of 1.60 A in the +x direction. There is the uniform magnetic field present, given by B=0.003i + 0.004j + 0.002k, where i, j, k are the unit vectors along cartesian coordinate axes') in units of Tesla. Compute the y-component of the magnetic force acting on a segment of wire of length L = 18.0 cm.
