Ok i need help and i will add u as my friend if u help me

Sound

Explanation:

Hi there,

To best answer this question, look at the pattern of how different energy forms are related. Notice, the energy associated with Light also creates Heat, and the energy creating Heat created Light.

Similarly, kinetic energy (the energy of motion and movement) typically creates sound as well, which are vibrations of air in longitudinal waves. Notice, the Blender and Fan create Energy of Motion, and thus create Sound.

Apply this to Washing Machine, the Energy of Motion also creates Sound. This makes sense, as Washing Machines use motors for kinetic energy to rotate clothes, which does not make heat, light, or additional motion. Just sound!

Thanks,

you need to give more information

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
