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.

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge
