Answer:
the volume of the sound will quarter
Explanation:
As you move far away from the source, the loudness of sound decreases. This is because as the distance from the source increases, the area it covers also increases thereby spreading the energy over a great area leading to lesser loudness and intensity.
As a result of this, sound intensity follows an inverse square law:
I ∝ 1/d²; where I is the intensity and d is the distance from source.
Therefore If a speaker is moved from 2 feet away to 4 feet away (increment of 2 feet), the volume of the sound would quarter (1/2² = 1/4)
Answer:
There are 98.9% of carbon atoms
Explanation:
Answer: 15.7 liters
Explanation: reaction is 2H2 + O2. -> 2H2O
Because all substance still are gases, volumes in
STP conditions are proportional to amount of moles.
Amount of water is same as Hydrogen. Also volume is same.
Answer:
A mineral is an inorganic solid substance formed naturally in the ground having a definite physical and chemical properties.
The internal atomic structure or arrangmenet of atoms of a mineral determines the chemical and physical properties of the mineral.
For example: diamonds and graphite, atmoic structure of diamond is rigid tetrahedral network providing chemical and physical properties of diamond.
