Answer:
Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium. The human ear detects sound waves when vibrating air particles vibrate small parts within the ear.
In many ways, sound waves are similar to light waves. They both originate from a definite source and can be distributed or scattered using various means. Unlike light, sound waves can only travel through a medium, such as air, glass, or metal. This means there’s no sound in space!
Explanation:
D the answer you’re looking for is letter d.
The maximum theoretical efficiency of the system is the one corresponding to the efficiency of a Carnot cycle operating between the same temperatures of the system:
where
and
are the cold and hot temperatures, respectively.
In our problem,
and
, therefore the maximum theoretical efficiency is
So, 33%.
I think being self disciplined is when you are a responsible and mature person and maybe raised yourself I don’t know what else to write you can expand on this
