The correct option is

the point about which an unconstrained rotation occurs

Explanation:

The CENTER OF MASS is the average position of the different parts of the the object system which are weighted base on their masses

the point about which an unconstrained rotation occurs

the mass-weighted center of the object

Explanation:

The center of mass of an object can be described to be a a position that is defined relative to the object

The center of mass is the average position of every parts of the object. At this point we can assume that all of the mass of this object is concentrated

When weighted according to their masses, the center of mass is the average position of all the parts of the object. While other points in this object are rotating around it, the center of mass would not rotate (fixed).

So the correct options are:

1. the point about which an unconstrained rotation occurs

2. the mass-weighted center of the object

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
