Police can estimate the speed a car had been travelling using the length of the skid marks. One formula used for this purpose is v=-7+8.2 $\sqrt{d}$√ d , where v is the speed, in kilometres per hour, and d is the length of the skid marks, in metres.
c.) What would have been the speed of a car, to the nearest kilometre per hour, that would have resulted in 150m skid marks?

A student set up an electrolytic cell similar to the one in the Electrolysis experiment to collect hydrogen gas over water in a burette, using a small strip of lead metal as the anode (instead of copper). Before the electrolysis, the mass of the lead strip was 8.218 g. A current of 121.1 mA was applied for a period of 3600 seconds, during which time some of the lead metal was oxidized to lead (2+). What was the mass of the lead metal strip at the end of the electrolysis?
Final mass of lead strip = ? g
