Solution :
Let, intensity at distance 3 m from the acoustic source is .
We need to find the distance d where the intensity is .
Now, we know intensity is inversely proportional to square of distance between the source.
Therefore, intensity will be halved at a distance of .
Answer: Volume of 1g of pure gold
Given;
Density of a pure gold=19.3
Mass of a pure gold =1g
To find:
Volume of 1g of pure gold
Solution:
According to the formula,
Density= Mass/Volume
Where =density of pure gold
m=mass of pure gold
v=volume of pure gold
From the above equation volume can be calculated as
Substitute the values of mass and density value in the above equation
Result:
Thus the volume of 1g of pure gold is
