Why is the law of gravity an example of a universal law? A) Gravity exists between any two masses.

B) Gravity exists only on the earth and the moon.

C) Gravity exists for masses in a closed system only.

D) Gravity exists between small masses in an open system only.

A

Explanation:

The most important part about this is not only that objects pull on each other, but that two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is known as Newton's law of universal gravitation.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

your answer is, orbit around the nucleus
