What provides information about the body position with respect to gravity?​
patriot [66]

Answer:

Centre of Gravity

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[1]. Because it is a hypothetical point, the COG need not lie within the physical bounds of an object or person. One subjective way (there are objective measures) to approximate the COG of an object is to visualise it balancing on one finger.

Centre of Gravity in the Human Body

In the anatomical position, the COG lies approximately anterior to the second sacral vertebra. However, since human beings do not remain fixed in the anatomical position, the precise location of the COG changes constantly with every new position of the body and limbs. The bodily proportions of the individual will also affect the location of the COG.

Answer:Answer:

For 1: The correct answer is Model 1, 2, and 4.

For 2: The correct answer is Option 1.

Explanation:

For 1:

An element has 3 subatomic particles: electrons (E), neutrons (N) and protons (P).

Atomic number is defined as the number of protons or number of electrons.

Atoms having same number of protons are same. From the given models, Model 1, 2 and 4 have 2 protons with different neutrons. Hence, these models belong to same element.

For 2:

A compound is defined as a substance in which two or more types of elements combine in a fixed ratio. For Example:  is a compound made out of atoms of carbon and oxygen.

Hence, the correct answer is Option 2.
