Step-by-step explanation:

in science and technology, the weight if body in a particular reference frame is defined as the force that gives the body and acceleration equal to the local acceleration of free fall in that reference frame

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
