Find the temperature at the bottom of the Denmark Strait cataract fall which is 11, 500 feet tall. The water temperature on the top of the fall is 10.0 degree C.

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.
