5.Considere una tobera adiabática en la cual entra vapor con un flujo másico de 4,167 kg/min. Al entrar el vapor tiene una energía interna específica de 2 510 kJ/kg, una presión de 1,378 MPa, un volumen específico de 0,147 m3/kg y una velocidad de 5 m/s. Las condiciones de salida son P = 138,7 kPa, volumen específico de 1,099 m3/kg y energía interna específica de 2,263 MJ/kg. Determina la velocidad de salida.​

An isotope undergoes radioactive decay by emitting radiation that has a –1 charge. what other characteristic does the radiation have?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

A0.750 kg aluminum pan is removed from the stove and plunged into a sink filled with 10.0 kg of water at 293 k. the water temperature quickly rises to 297 k. what was the initial temperature of the aluminum pan? the specific heat of aluminum is ca = 900 j/(kgk) and water is cw = 4190 j/(kgk)
