In the previous problem you found out that that the ratio between enterprise's speeds at points a and b on the elliptical (transfer) orbit is 1/3. since there are no forces acting on the enterprise+ earth system the total mechanical energy of the system is conserved while enterprise is moving on the elliptical orbit. write that the total energy in points a and b is the same and find the entrance (va ) and exit (vb ) speeds the entreprise must match exactly in order to leave the outer circular orbit and engage onto the inner circular orbit. give your answer in terms of g, me and r. enter a comma between the two expressions

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
