- What is the power in kW produced by the La Rance tidal power station in France if the usable tidal range is 10 m? The barrage is 140m long and the area of the basin behind the barrage is 22 km2. Tidal period is 12h 25minutes. Density of salt water is 1020 kg/m3. Use proper units and 3 significant figures.Show that the gravitational potential energy of an object of mass at height on Earth is given by PEg = mgh.A tourist purchases a car in England and ships it home to the United States. The car sticker advertised that the car's fuel consumption was at the rate of 40 miles per gallon on the open road. The tourist does not realize that the U.K. gallon differs from the U.S. gallon: 1 U.K. gallon = 4.545 963 1 liters1 U.S. gallon = 3.785 306 0 liters For a trip of 731 miles (in the United States), how many gallons of fuel does (a) the mistaken tourist believe she needs and (b) the car actually require?
- The power available from a wind turbine is calculated by the following equation: Question Help ▼ P = where P= power [watts], A=sweep area (circular) of the blades [square meters], p= air density [kilograms per cubic meter], and v=velocity [meters per second].
