Question

Q.1 What do you mean by equilibrium ?
Q.2 What do you mean by centre of gravity?
Q.What do you mean by long bones?

Answer 1

Answer:

• A condition in which all influences acting upon it are canceled by others, resulting in a stable, balanced, or unchanging system. The state of a chemical reaction in which its forward and reverse reactions occur at equal rates so that the concentration of the reactants and products does not change with time.
• The centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated. Because it is a hypothetical point, the COG need not lie within the physical bounds of an object or person.
• Long bones are hard, dense bones that provide strength, structure, and mobility. The thigh bone (femur) is a long bone. A long bone has a shaft and two ends. Some bones in the fingers are classified as long bones, even though they are short in length.
