The following marks were recorded on air table where the time constant is adjusted at 100ms: A1A2A3 A4 A5 A6
A1A2=4cm A2A3=8cm A3A4=12cm A4A5=16cm A5A6=20cm
a) Find the average speed of the puck between A2 and A6.

When a lead acid car battery is recharged by the alternator, it acts essentially as an electrolytic cell in which solid lead(ii) sulfate is reduced to lead at the cathode and oxidized to solid lead(ii) oxide at the anode. suppose a current of is fed into a car battery for seconds. calculate the mass of lead deposited on the cathode of the battery.
