Adiver swims in a pool that is 30 m deep. the diver swims 20 m above the bottom. if the diver descends to 10 m above the bottom, what is the absolute pressure?

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.
