Why is energy needed by the body?
Energy is needed to keep your body in action!
What energy is the energy needed to start a reaction?
Activation Energy.
Why do we need energy to live?
To move muscles, the brain generates an electric pulse and sends it through nerves to the muscle, causing it to contract. To generate this pulse, the brain needs energy. Energy is also needed for the muscles themselves to move (the electric pulse is a signal, rather than a power source). In warmblooded animals (such as humans), energy is also used to maintain body temperature.
What is needed to operate a machine?
What is needed to operate a machine is energy.
What is the definition of activation energy?
Energy needed to get a reaction started....
What from of energy might be needed for a chemical reaction to take place?
heat & electric energy !
Why is an energy source needed in order to have a working electric circuit?
Ultimately this is a special case of the Second Law of Thermodynamics.In the case of an electric circuit, consider Ohm's Law. Without a voltage, you will have no current. Also, if a current flows, keeping up the voltage requires power.
Is it true that an electric spark can provide the activation energy needed to start a combustion reaction?
yes
Is a power supply needed to run an electric motor?
Yes. To make something move, you have to add energy. An electric motor won't turn by itself.
Does electric fan when running when it is not needed is waster of energy?
yes anything that is plugged in an electrical socket is wasting energy regardless if it is being used or not
How do you save on electric bill for lighting?
Solar Panels Low energy light bulbs Switch off (or remove) bulbs that are not needed.
For an electric current to flow the only thing needed is for two objects to have a difference in charge?
Actually, they need a difference in energy per charge. Voltage is energy per charge, in joules per coulomb, and a voltage differential is what is required to create an electric current flow.
Ways to conserve coal?
Use only the necessary amount of energy needed,i.e., turn off electric devices when not needed etc. Insulate your homes. This way lesser heat would escape the house and less energy would be spent on the usage of heaters. And promote and use renewable energy resources such as HEP, solar energy, tidal energy etc.
What process converts chemical energy to a mechanical energy?
An engine is needed to do this. A steam engine A jet engine A car engine A battery driven electric engine. The process is normally multi step.
What has the author Glenn R Schleede written?
Glenn R. Schleede has written: 'Will the energy that the New England region is counting on for 2000-2010 be available when needed?' -- subject(s): Electric power transmission, Electric power-plants, Electric utilities, Energy consumption, Forecasting, Gas power plants, Natural gas, Rates
Energy is the energy needed to start a chemical reaction?
The energy needed to statr a chemical reaction is the 'Activation Energy' , which is given the symbol (Ea).
Why is energy needed by the body?
Energy is needed to keep your body in action!
