The pink car has a velocity of 4.4 m/s to the right while the blue car has a velocity of 6.8 m/s to the left.
If the two cars crashed and stuck together, what would their

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.
