An air-standard Stirling cycle operates with a maximum pressure of 3,200 kPa and a minimum pressure of 50 kPa. The maximum volume is 13.6 times the minimum volume, and the low-temperature reservoir is at 23C. Allowing a 5C temperature difference between the external reservoirs and the air when appropriate, calculate the specific heat added to the cycle and its net specific work. Use constant specific heats at room temperature

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
