A 45 kg rigid body is initially at rest at P.2) O on a frozen lake. Is it possible that once it has exploded into the three pieces, A, B, C, with masses ma = 20 kg, mB = 15 kg, and mc = 10 kg, it can occupy the illustrated configuration rAo = 70i m, at some later time? 50j m, r (30i + 20j) m, and %3D A j

Looking for detailed solution asap!!

5. (a) There is 1000 kg water in a swimming pool. Consider the liquid water as an incompressible model at room temperature. If the temperature of the water body is increased by 3 degrees C (assuming this temperature change is uniform across the entire pool), determine: (i) the total internal energy change of the water, (ii) the total enthalpy change of the water. Use a constant heat capacity of water c = 4.211 kJ/kg. K. (b) In a big closed room, there is 1000 kg of air. Suppose the air is an ideal gas model at room temperature. The temperature of the room is increased by 3 degrees C heated by an electric heater. Suppose this temperature change is uniform across the entire room. (iii) Determine the total internal energy change of the air. (iv) Determine the total enthalpy change of the air. Use constant heat capacities of air c₂ = 0.718 kJ/kg . K and Cp = 1.005 kJ/kg.K.

Q. - ome kg of an ideal gas (R = 287 J um irreversible Process from Stelte - 0 [1 bar, 300 k] to State - [2 bar, 300k]. The entropy change (S2-S1) J kg-k

Edición P3. A piston-cylinder system contains 1 L of water at 105°C and 85% quality. I know adds energy, causing the plunger to travel until it makes contact with a spring of constant K = 100 N/mm, just at this moment, the volume of the water is 50% greater than the initial. The energy transfer continues until the volume is 1.7 L, and the temperature of the water reached 600°C. Make a schematic of the system according to the statement and calculate the water pressure when T = 600°C. Answer: 198.16kPa
