Amonatomic ideal gas initially fills a v0 = 0.35 m3 container at p0 = 85 kpa. the gas undergoes an isobaric expansion to v1 = 0.75 m3. next it undergoes an isovolumetric cooling to its initial temperature t0. finally it undergoes an isothermal compression to its initial pressure and volume.

(a) identify the p-v diagram that correctly represents this three step cycle.
(b) calculate the work done by the gas, wi, in kilojoules, during the isobaric expansion

How do you tell if someone actually cares about you? and just say they do?

You want to lose weight and have been trying to decide which type of fad diet is best for you. you ask your doctor, who responds that a. fad diets are a temporary fix but generally don't have any side effects b. fad diets can be used several times a year to maintain a healthy weight c. fad diets can be risky for your health and, in the long run, do not work d. fad diets should never be used one right after the other; there should be a break between them select the best answer from the choices provided. a b c d

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
