Use the formula for gravitational potential energy:
PE = mgh
Replace the numbers you know: energy (PE), mass, and a gravity of about 9.8. Solve the resulting equation for height. Since you are using standard SI units, the answer will be in meters.

A vacuum uses input energy of 200 000 j to clean a carpet if 140 000 j of output energy is waste energy what is the efficiency of the vacuum?
This question means that 60 000 J is used usefully (this is used to produce the kinetic energy of the air flow that does the cleaning), so the ratio of useful energy to the total is 60/200 which is 30 percent. This is the efficiency of the device.
How many kilograms are in 40000 centimeters?
Kilograms and Centimeters are two completely different units of measurement. Kilograms is for mass, Centimeters for length/distance. 40 000 Grams, is 40 Kilograms though. 1000g = 1kg
How much energy does a nuclear reaction give off?
It depends on how much you are reacting, what element it is, and how quickly it reacts. But in all cases E=mc^2 Meaning that the energy (in Joules) released is equal to the mass lost (in kg) multiplied by the speed of light (300 000 000 m/s) squared.

How much energy does Canada consume in one year?
The United States is the largest energy consumer in terms of total use, using 100 quadrillion BTU (105 exajoules, or 29000 TWh) in 2005, equivalent to an (average) consumption rate of 3.3 TW. The U.S. ranks seventh in energy consumption per-capita after Canada and a number of small countries. The majority of this energy is derived from fossil fuels: in 2005, it was estimated that 40% of the nation's energy came from petroleum, 23% from coal, and 23% from natural gas. The remaining 14% was supplied by nuclear power, hydroelectric dams, and miscellaneous renewable energy sources.
