Study the vector diagram. Three vectors are drawn tail to tip method in the x y plane. Vector labeled T starts at the origin and is drawn in the northeast direction. The second vector is labeled U and drawn in the south south east direction. The third is labeled V and drawn in the north northeast direction. X and Y components are drawn for each vector along the x and y axis.

Which formula can be used to find the x-component of the resultant vector?

Tx - Ux - Vx
Tx + Ux + Vx
Tx = Tcosθ
Tx = Tsinθ

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?
