max velocity can only be obtained when sin(wt + phase constant) is equal to 1. that should get you started. Also think about the position of the object when the speed is equal to 0 and how long it takes to get there. That should help you find the period as well.

Because of the flow of the engine. Let's take it in sections: starting at the top left corner, the system moves down and to the right, and everything below this part of the graph would be positive. Delta V in this case would be positive. Once it goes back up and back to the left Delta V in...

Oh I'm very sorry, did you try negative? How many chance do you get?

Correct, Thank you very much!

My suggestion is to convert .01 atm to Pa FIRST. as in .01 atm = 1013.25 Pa <-- that is now your height there is no need to convert the Volume so W = 1013.25 * 6 Answer will be in Joules OH THE CONVERSIONS!

It looks to me like h is wrong. It looks like it is 1/3 of Pmax

Work will be the area of the box the system creates. You can approximate the area just by looking at the graph, and using formula for area of a parallelogram, which this appears to be.

Homework Statement One mole of a dilute gas initially has a pressure equal to 1.00 atm, and a volume equal to 12.0 L. As the gas is slowly heated, the plot of its state on a PV diagram moves in a straight line to the final state. The gas now has a pressure equal to 5.00 atm, and a volume...

If n is the same, then they would have the same number of moles. But does that mean that their masses are the same? as in: [x]The total mass of gas is the same in both vessels. []None of these statements are true. []The average speed of the gas molecules is the same in both vessels. [x]The...

Homework Statement How much heat must be removed when 130 g of steam at 145°C is cooled and frozen into 130 g of ice at 0°C. (Take the specific heat of steam to be 2.01 kJ/kg·K.) Answer is in kcal. Homework Equations The Attempt at a Solution I know steam turns back into...

Added the ideal gas law and looked at the problem again, but I'm still not sure.

anyone have any ideas?

Homework Statement Two identical vessels contain different ideal gases at the same pressure and temperature. Which of the following statements are true? (Select all that apply.) []The total mass of gas is the same in both vessels. []None of these statements are true. []The average...
