Assume that 1 ton is the metric tonne, 1000kg. The force exerted by the car on the ground is 1000 x 9.81 Newtons. (the acceleration towards the earth due to gravity is 9.81 m/sec2 under freefall conditions).
Therefore the equation for work done in raising height H meters is
H x 1000 x 9.81 = 250,000 joules, so H = 250,000/1000 x 9.81 = 25.48 meters
If the car is lifted twice as high, its potential energy would be four times as much. Potential energy is directly proportional to the height to which an object is lifted, so doubling the height would result in a quadrupling of potential energy.
To calculate the increase in potential energy for each book, you multiply the force applied by the distance lifted. For the 20-newton book: 20 N * 0.5 m = 10 Joules. For the 25-newton book: 25 N * x = 10 Joules (where x is the height). Solving for x, x = 0.4 m.
The energy released in a nuclear reaction can vary widely depending on the reaction. However, typically nuclear reactions involve very high energy levels, on the order of millions to billions of joules. This is due to the large amounts of energy stored in atomic nuclei.
The potential energy of the object is given by the formula: potential energy = mass * gravitational acceleration * height. Plugging in the values: potential energy = 5 kg * 9.8 m/s^2 * 3 m = 147 Joules.
The word in your question that I keyed on is "resting". An object at rest has zero kinetic energy. If you meant potential energy, the answer is 1500 joules.

A joule is a unit of energy, not a unit of power. A watt is the same as a joule per second, so depending on how long it takes to output a million joules, the power can be very high, or very low.
The Infrastructure Budget Committee will be happy to hear about this one. Your engineers are not demanding a lot of work out of that water. 1,000 kg of water releases 5,000 joules of energy when it falls about 51 centimeters (20 inches).

If you weigh 70 kg and the stairs are 3 metres high, the energy needed is 70 x 9.8 x 3 Joules or 2058 joules. That would keep a 60 w bulb going for 2058/60 seconds, or 34.3 seconds. But to produce that same energy in a generating plant, the fuel energy wasted in the process would be between 2000 joules for a gas plant of 50% efficiency, and 6000 joules for a coal plant of 25% efficiency.
Well gravitational potential energy is potential energy that depends on the height of an object so an object would have gravitational potential energy when ever it's of the ground or at a high height (it doesn't have to be very high) for example if you lift up a ball it has the potential to fall or if your climbing a mountain you have gravitational potential energy.
The idea is to use the formula for potential energy: PE = mgh. Replace the numbers you know, and solve for the missing number.
