An ideal monatomic gas expands isobarically from state a to state b. it is then compressed isothermally from state b to state c and finally cooled at constant volume until it returns to its initial state a.
= 4 x 10⁻³ = 8 x 10⁻³ = = 1 x 10⁶ = 2 x 10⁶ = 600 k
what is the temperature of the gas when it is in state b?
how much work is done by the gas in expanding isobarically from a to b?
how much work is done on the gas in going from b to c?
the graph is a pv diagram. it does not show any other numbers on it other than what is given.

Plss anybody know how to do this? ? i need the answers from a through d

Astudent pushes on a 20.0 kg box with a force of 50 n at an angle of 30° below the horizontal. the box accelerates at a rate of 0.5 m/s2 across a horizontal floor. what is the value of the normal force on the box? 200 n 243 n 156 n 225 n

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?
