Answer: B. Wave A is louder than Wave B.
Explanation: The loudness of sound is measured in unit called decibels (dB).
A decibel unit measures the relative intensity of sounds on a scale from zero to about 100 dB. dB is a measure of intensity, which relates to how much energy the pressure wave has.
Given : Wave A is rated at 100 dB, and Wave B is rated at 90 dB.
Thus we can infer that as wave A has a higher value than wave B, wave A is more louder than wave B.
It is said that the materials found in the giant cloud that formed our solar system are comparable to the ones we have in the solar system today, which are Hydrogen and Helium!
Humans increasingly dominate the landscape, a force largely driven by population growth and dispersion. In the United States and worldwide, rural landscapes in many places are transforming to exurban and eventually public uses.
<h2>What happens for elements larger than iron to be created? </h2>
- Neutron-capture inside stars is the primary source of elements heavier than iron, while there are other minor contributors (cosmic ray spallation, radioactive decay). They are not just produced by supernovae, but also by other stars.
