Answer: intensity (I2) = 0.8W/m²
Explanation: The relationship between the intensity of sound wave obeys the inverse square law, that's the intensity (I) is inversely proportional to square of distance (r).
I α r², I= kr²
I1 * (r1)² = I2 * (r2) ²
From the question,
I1 = 0.050W/m², r1 = 140m, I2 =?, r2= 1/4 * 140 = 35m.
By substituting the parameters, we have that
0.05 * (140)² = I2 * (35)²
0.05 * 19600 = I2 * 1225
980 = I2 * 1225
I2 = 980/1225
I2 = 0.8W/m²
It is more similar to a noble gas because noble gases are the group 18 elements. Noble gases are gases which have their outer shell complete and so cannot give out or gain any more electrons. And cannot react with other elements.
We have that the Table for the Factors is
From the Question we are told to
Organize the following measurements from smallest to largest
- Kilometer,
- Nanometer
- Centimeter
- Meter
- Micrometer.
Note that we Determine the multiplying factor by using Metre which is the SI unit of length as the bases

Answer:
There are four natural states of matter: Solids, liquids, gases and plasma.
Explanation:
The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don't move much.
I believe the answer is C
