This figure shows the angular displacement of a pendulum on a planet with twice the earth's gravity. How long is the pendulum's string? A graph titled Angular Displacement of Pendulum. The horizontal axis is labeled Time, in seconds, and extends from 0 to 5.0 with an interval of 1.0. The vertical axis is labeled Angular Displacement, in radians, and extends from negative 0.3 to positive 0.3 with an interval of 0.1. The graph shown is a sine wave beginning at the origin. The sine wave peaks are at about 2.5 and its troughs are at about negative 2.5. From 0 to 5 seconds, the sine wave completes about 5 and one-half cycles.

A) 3.22 m

B) 0.80 m

C) 0.40 m

D) 1.61 m

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)
