Define a function drawcircle. this function should expect a turtle object, the coordinates of the circle’s center point, and the circle’s radius as arguments. the function should draw the specified circle. the algorithm should draw the circle’s circumference by turning 3 degrees and moving a given distance 120 times. calculate the distance moved with the formula 2.0 × π × radius ÷ 120.0. define a function main that will draw a circle with the following parameters when the program is run: x = 25 y = 75 radius = 100

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, 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 +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
