At its deepest, happy valley is close to 330 m (a bit over 1000 feet) deep, and it once was at least as high as the mountains around the valley. let us call the thickness of rock removed from the valley each year, your answer in the previous blank, 0.33 m. then the depth of the valley, 330 m, divided by the erosion rate, 0.33 m/yr, yields the number of years it took to hollow out happy valley, . this should be a large number.

In what direction does the medium move relative to the direction of the wave? explain.

A2.0 μf capacitor and a 4.0 μf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg. how much energy e must be supplied to the device? express your answer in joules.
