What is a machine that operates without an external power source?
A wind-up mechanical clock operates without an external power source by storing potential energy when wound up, which is then released gradually to power the clock's mechanism.
What machine that operates without any external power source?
A wind-up clockwork device is an example of a machine that operates without an external power source. It functions solely through the energy stored in its wound-up spring mechanism.
How does a perpetual magnet wheel generate continuous motion without the need for an external power source?
A perpetual magnet wheel generates continuous motion without an external power source through the interaction of magnetic fields. The magnets on the wheel repel and attract each other, causing the wheel to spin continuously. This motion is sustained as long as the magnets maintain their magnetic properties.
What are magnets that do not require any power of force to maintain their field called?
They are called permanent magnets. These magnets retain their magnetic field without the need for any external power source or force to maintain them.
Why does a heat pump need an external source or energy?
A heat pump requires an external source of energy to transfer heat from a low-temperature area to a high-temperature area. This process of moving heat against the natural flow requires energy input, typically in the form of electricity, to power the compressor and circulate the refrigerant.
Is there any amplifer which will work without an external current source?
An amp with no power supply? No. Can't be done. An amplifier increases the current of the input signal, and to do so it needs power to do it with.
Passive prosthetics came about to meet what need?
the need for devices to function without an external power source
What is the power source of external combustion engines?
The power source is the expansion of the working fluid in turn producing thrust.
What is a machine that operates without an external power source?
A wind-up mechanical clock operates without an external power source by storing potential energy when wound up, which is then released gradually to power the clock's mechanism.
Which process requires an external power source?
Electrolysis is a process that requires an external power source. This process uses electricity to cause a chemical reaction that splits compounds into their constituent elements.
What are the passive transducer?
Passive; operates without the needs of external power
How was coal the main source of power?
It was used for most power needs
Why are rocks better than computers?
They don't require an external power source.
What needs a motor?
A person needs a motor when there is a need for mechanical energy with availability of a power source.
What machine that operates without any external power source?
A wind-up clockwork device is an example of a machine that operates without an external power source. It functions solely through the energy stored in its wound-up spring mechanism.
If you get replacement body parts does that make you a cyborg?
No. Many people have knee and hips replaced. It depends on your definition of cyborg. If you require a cyborg to have IC electronics and a power source then simple prosthesis would not a cyborg make.
What power source needs to be replaced every fifty years?
nuclear reactor on ship
