Question

Define : (1) Fermentation (2) Electrostatic force ​

Answer 1

Answer:

i) Fermentation, chemical process by which molecules such as glucose are broken down anaerobically. More broadly, fermentation is the foaming that occurs during the manufacture of wine and beer, a process at least 10,000 years old.

ii) Electrostatic force is the force exerted by a charged body on another charged or uncharged body. This is because the comb is charged because of the rubbing on your hair and it attracts uncharged objects like paper. Gravitational force is a force exerted by the earth on all objects on it.

Answer 2

Heya mate!

Answer:

(1) Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.

(2) Electrostatics is a branch of physics that studies electric charges at rest. Since classical physics, it has been known that some materials, such as amber, attract lightweight particles after rubbing. The Greek word for amber, ήλεκτρον, or electron, was thus the source of the word 'electricity'.
