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

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?

Which safety measures should you follow during a thunderstorm? check all that apply. (a) avoid touching anything that conducts electricity. (b) avoid touching a person who has been struck by lightning. (c) go outside. (d) keep your computer turned off. (e) stay out of water. (f) stay inside.

This is one type of line graph in which the independent variable is time plotted on the x axis and the dependent variable, also numerical, is plotted on the y axis.
