Vector subtraction ( A-B) is a special case of vector addition, since A-B = A + (-B). Suppose that the cases of vectors addition 1, 2,3in this experiment were vector subtraction (F1-F2)

Vector subtractions

1 : in the second quadrant whereas previously it was in thefirst quadrant

2 : in the second quadrant whereas previously it was in thefirst quadrant

3 : in the first quadrant whereas previously it was in thefirst quadrant.

Would the magnitude of the resultant be different forvector subtraction than for vector addition in each case? if so ,state whether the subtractive resultant would be greater or lessthan the additive resultant.

Air is held within a frictionless piston-cylinder container, which is oriented vertically. the mass of the piston is 0.45 kg and the cross-sectional area is 0.0030 m2. initially (state 1) the pressure of the gas is sufficient to support the weight of the piston as well as the force exerted by the atmospheric pressure ( 101.32 kpa). the volume occupied by the air within the cylinder in state 1 is 1.00 liter. one end of a spring (with spring constant k = 1000 n/m) is attached to the top of the piston, while the other end of the spring is attached to a stage that can move vertically. initially the spring is undeflected and therefore exerts no force. then the stage is then moved quasistatically downward a distance of 10.0 cm, at which point the system reaches state 2. the piston-cylinder is not insulated; rather it remains in diathermal contact with the surroundings, which are at a constant temperature of 300 k. what is the change of pressure within the container?
