As you saw in part a, io's elliptical orbit is necessary to its tidal heating. this elliptical orbit, in turn, is a result of the orbital resonance among io, europa, and ganymede. this orbital resonance causes io to have a more elliptical orbit than it would otherwise, because and ganymede are unusually large moonseuropa and ganymede always pull on io from the same direction as jupiter pulls on ioio periodically passes europa and ganymede in the same orbital positionall three moons orbit with the same period, staying aligned at all times

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?

What are igneous intrusions and extrusions

2kg of refrigerant 134a undergoes a polytropic process in a piston-cylinder assembly from an initial state of saturated vapor at 2 bar to a final state of 12 bar, 80 degree c. a)determine the work for the process in kj. b)sketch the process on a p-v diagram.
