Dimensional Analysis. Dimensional Analysis (also called Factor-Label Method or the Unit Factor Method) is a problem-solving method that uses the fact that any number or expression can be multiplied by one without changing its value. It is a useful technique.
In 1887, the first dry cell battery was invented. Unlike previous batteries, it used a paste electrolyte instead of a liquid.
The leadâacid battery was invented in 1859 by French physicist Gaston Plante plantÃ© and is the oldest type of rechargeable. Battery despite having a very low-energy-to weight ratio and a low-energy-to volume, ratio its ability to supply high surge currents means that the cells have a relatively large-power-to weight. ratio
