Aglass pipe system has a very corrosive liquid flowing in it (think hydrofluoric acid, say). the liquid will destroy flow meters, but you need to know the flow rate. one way of measuring the flow rate is to add a fluorescent dye to the liquid at a known concentration, and then downstream activate the dye by uv light and then measure the dye concentration by emitted light. if the dye is added at 1.00 g/s, and the dye concentration downstream is 0.050% by mass, what is the unknown flow rate in kg/h

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
