Suppose you spray your sister with water from a garden hose. The water is supplied to the hose at a rate of 0.405×10−3 m3/s and the diameter of the nozzle you hold is 5.77×10−3 m. At what speed does the water exit the nozzle?

When a resistor with resistance r is connected to a 1.50-v flashlight battery, the resistor consumes 0.0625 w of electrical power. (throughout, assume that each battery has negligible internal resistance.) what power does the resistor consume if it is connected to a 12.6-v car battery? assume that r remains constant when the power consumption changes.
