Figure 1 shows that the two vectors in different direction respectively. Determine the resultant for the two vectors

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

What object a collides with object b and bounces back its final momentum is?
