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.​

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

Hydrogen atoms are excited by a laser to the =4n=4 state and then allowed to emit. what is the maximum number of distinct emission spectral lines (lines of different wavelengths) that can be observed from this system? 8 6 2 7 4 5 1 3 calculate the wavelength of the 4⟶14⟶1 transition. =λ=
