Set of coordinate axis in terms of which the position of the body in motion may be specified

The force needed to compress or lengthen a elastic body a certain distance is proportional to the distance. What law are we talking about?

"Any external pressure applied to a fluid is transmitted into the liquid in all directions and onto the walls of the container" Write the name of this scientific statement whose most important application is hydraulic pump.

What is the net force acting on a 20 kg body that is accelerating 2m/s2 ?

If no net force is applied, the object will stay at rest or will move at a constant velocity following a straight line.
