Answer:
Option B
Explanation:
The pH scale is a way of determining a substance acidity, and it is logarithmic. As a result, each pH value is ten times more acidic than the next higher value. Therefore, pH 4 is ten times more acidic than pH 5 and 100 times (10*10) more acidic than pH 6.
According to finding of scientist, the earth is roughly 4,600 million years old. then the non abundant fossil that they dated was about 3,600 million years old. so the fraction or percent of <span>geologic time is :
3,600 / 4600 = 0.78 or 78 % of earth geologic time</span>
Answer:
First of all, there is less pollution. Also, solar energy is that it is renewable
<h3><u>Answer;</u></h3>
Compressions
Rarefactions
<h3><u>Explanations;</u></h3>
- A wave is a transmission of a disturbance from one point to another, and involve the transfer of energy from the source to another point.
- Waves may be classified as longitudinal waves or transverse wave depending on the vibration of particles relative to the wave motion or mechanical and electromagnetic waves based on the material medium of transmission.
- <em><u>Sound waves are examples of longitudinal waves that are mechanical waves since they require material medium for transmission. Longitudinal waves involves transmission of waves such that the vibration of particles is parallel to the wave motion , creating compressions and rarefactions.</u></em>
