When an automatic battery is fully charged the sulfuric acid and water mixture will have a specific gravity of about
Archy [21]

the specific gravity of pure sulfuric acid is---------> approximately 1.835 g / cm3

the specific gravity of water is -------------------- >1.000 g / cm3.

 The electrolyte, that is, the dissolution of sulfuric acid in water, is usually at a rate of 36% acid, so that, in a fully charged element, we can deduce the electrolyte density, is 1.295 g / cm3. (see attached table)

The specific gravity is actually the difference in the weight of water compared to a specific fluid. It is measured with a hydrometer

What three mechanisms regulate the heart?
Tamiku [17]
The three mechanisms which regulate the heart are endocrine, cardiovascular and Sinoatrial nodes.
The endocrine system consists of the glands and hormones of the human body. The cardiovascular system is the organ system which is responsible for the circulation of the blood around the body and the oxygenation of the body's tissues. The sinoatrial node (SA node) generates the electrical impulses and is considered the natural pacemaker of the heart.
