How much energy is wasted for every 1000 megajoule?
It depends on the efficiency of the appliance. If an electric motor has an efficiency of 0.7, then for every 1000 megajoules, 30 megajoules will be wasted as useless heat or sound or other useless energy form.
Laws of conservation of energy and briefly explain?
The law of conservation of energy basically states that you can't create energy out of nothing. You also can't destroy energy. Energy is a quantity that remains constant, in a closed system (one that has no contact with the outside world). The law of conservation of energy is also called the First Law of Thermodynamics.You can, however, convert useful energy into useless (or unusable) energy - and this can no longer be converted back to useful energy - in other words, there are irreversible processes in nature. This is the Second Law of Thermodynamics.The law of conservation of energy basically states that you can't create energy out of nothing. You also can't destroy energy.

Friction doesn't convert energy if actually destroys it true or false?
Not QUITE true. Friction can convert usable energy in useless (or unusable) energy, but energy itself can't be destroyed.
What is energy of motion is called?
Energy of motion is called kinetic energy.
The energy an object has because of its motion is called potential energy?
No. Energy related to motion is called kinetic energy; energy related to position is called potential energy.No. Energy related to motion is called kinetic energy; energy related to position is called potential energy.No. Energy related to motion is called kinetic energy; energy related to position is called potential energy.No. Energy related to motion is called kinetic energy; energy related to position is called potential energy.
Is the amount of disorder or useless energy in a system?
Entropy
Why is energy needed in a reaction?
To do work. Without energy, everything would practically be useless
Who had a dog called useless?
From the British television series 'Monarch of the Glen'. The old man Hector MacDonald had a dog called Useless.
Bad things about solar energy calculators?
They will be useless without light

Where does energy go after its been used?
After energy has been used, the energy transforms to another type of energy. This energy is obviously not usable. This useless energy then collects in the sky to form more useful energies.

Why doesn't the principle of mechanical energy conservation hold in situations when frictional forces are present?
In the case of friction, energy is wasted, i.e., mechanical energy is converted into useless energy, mainly heat.
Is it likely that a programming language grammar will have a useless symbol?
There are many symbols in programming that have no means but it used in programmig is called useless symbols. like- #$%^&*@()
Is a light bullb renewable?
If you are talking about a normal light bulb no, the energy has been used and is now useless
What is energy of motion is called?
Energy of motion is called kinetic energy.
