El agua se fuerza hacia afuera de un extintor de incendios mediante presión de aire, como se muestra en la figura. ¿con qué rapidez sale el chorro de agua si la presión manométrica debido al aire encerrado es 400 kpa sobre la presión atmosférica cuando el nivel del agua está 0.500 m abajo de la boquilla? Se conoce que el radio del extintor es de 0.2 m mientras que el radio de la boquilla es de 2 mm.

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.

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

The amount of heat required to change liquid water to vapor at its boiling temperature is 2256 kj/kg. the amount of heat required to change liquid mercury to its vapor state at its boiling temperature is 295 kj/kg. one kg of each substance is currently at its boiling point. how will the amount of thermal energy required to change each substance from a liquid to a gas differ?
