What machine that operates without any external power source?
Perpetual Motion Machine
Why do mechanical systems need an external energy source in order to maintain motion?
Because they need a source of power for example a car needs petrol
Is pendulum of a clock example of Forced oscillation?
yes,because we supply power through battery ,battery is the external source.
Why electrons of cathode does not end up after some time because of its continuous emission of electrons?
Because the cathode is connected to an external source of power, from which electrons are continuously supplied to the cathode.
What is source in physics?
The source of power.
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.
Which process requires an external power source?
electrolysis?
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 are the passive transducer?
Passive; operates without the needs of external power
Why are rocks better than computers?
They don't require an external power source.
How was coal the main source of power?
It was used for most power needs
What machine that operates without any external power source?
Perpetual Motion Machine
What needs a motor?
A person needs a motor when there is a need for mechanical energy with availability of a power source.
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 is the Difference between active filters and passive filters?
Active transducers are those which require electric current (a source of energy) for working, while passive transducers are those which does not need an external source. Passive transducers directly produce electric signals without an external energy source.
Why do mechanical systems need an external energy source in order to maintain motion?
Because they need a source of power for example a car needs petrol
