Un gran tanque de agua lleno tiene un orificio circular de 3 mm de radio, ubicado 10 m por debajo del nivel del agua en el tanque. En la parte superior, el tanque no está cubierto. Calcula la velocidad a la que saldrá el agua y el volumen de agua a descargar por unidad de tiempo.

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz. what wavelength is produced?

In science and physics what is the standard unit of measure for speed?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
