Thirty-six grams of air in a piston–cylinder assembly undergo a stirling cycle with a compression ratio of 7.5. at the beginning of the isothermal compression, the pressure and volume are 1 bar and 0.03 m3, respectively. the temperature during the isothermal expansion is 1400 k. assuming the ideal gas model and ignoring kinetic and potential energy effects, determine: (a) the net work, in kj. (b) the percent thermal efficiency. (c) the mean effective pressure, in bar.

Agardener uses a wheelbarrow to move soil from a truck to his garden. on the first trip from the truck to the garden, the wheelbarrow is half-full of soil and the gardener applies a certain force to cause it to accelerate. on the second trip, the wheelbarrow is full of soil. although the gardener applies the same amount of force to the wheelbarrow, he cannot move it with the same rate of acceleration. what should the gardener do to move the wheelbarrow at the same rate of acceleration for the second trip?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
