A 12 g bead is strung on a long, straight wire. It is accelerated, with no friction, by a force that acts at an angle to the wire. If the force has a constant value of 0.15N and acts over a distance of 75 cm and if the bead's final speed is 3.0 m/s and it starts at 1.0m/s, what is the angle between the force and the wire? Be sure to convert to MKS units (meters, kilograms, seconds).F

I) a gas contained within a piston-cylinder assembly undergoes two processes, a and b, between the same end states, 1 and 2, where p1 = 10 bar, v1 = 0.1 m3 , u1 = 400 kj and p2 = 1 bar, v2 = 1.0 m3 , u2 = 200 kj: ' process a: process from 1 to 2 during which the pressure-volume relation is pv = constant. ' process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to state 2. kinetic and potential energy effects can be ignored. for each of the processes a and b, a) sketch the process on a p-v diagram. b) evaluate the work, in kj. c) evaluate the heat transfer, in kj.(ans : qb,12 = -65.0 kj)
