because you are so stupid.
Embrittlement is a loss of ductility of a material, making it brittle. Various materials have different mechanisms of embrittlement.
It effected people's lives by making, different materials with it.
The answer is essentially in the question. Sound is the sensation caused by vibrations in the air. The faster the vibrations, the higher the frequency. So, when an engine is revved, the frequency of the vibrations it creates increases, and it gives higher frequency sounds, perceived as an increase in pitch.

The ribosome is responsible for making proteins....these proteins are needed for energy... Similarly the mitochondria is responsible for making energy.. Get the picture?
yes
very much so, depending on the atomic makeup and density, you got different and louder sounds
Because different materials have different properties, and designers like to pick the ones best suited for the task.
Making vibrations
Hand gloves are made of different materials. You have different kind of gloves for winters or summers.

In a manufacturing company you would have:Sales Managers - responsible for making salesMarketing Manager - responsible for advertisingPurchasing Managers - responsible for buying raw materialsProduction Managers - responsible for making the productFinance Managers - responsible for the moneyCost Accountants - responsible for analysing costsIT Manager - responsible for computingHuman Resources manager - responsible for staff training and welfare.Product Development Managers - responsible for new product designPersonnel Management - responsible for hiring, firing, and trainingTHIS IS A PROFESSIONAL EDIT
the director is responsible for the movie and the script writers and responsible for making the script goood
An object vibrates to produce sound. So a soundmaking object is different from the one that is silent because it produces vibrations that the silent object does not.
