Water flows through the convergent/divergent channel at 0.06 kg/s. calculate the ideal head in mm at the piezo tube where the cross sectional area of the channel is 90 mm2. assume the density of water is 1000 kg/m3

In a system, when potential energy decreases, then entropy also decreases. true false

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

Which is not an example of how an object gains elastic potential energy by stretching? a. jumping on a pogo stick b. pulling on a rubber band c. jumping on a trampoline
