The difference between the two mentioned magnitudes is 4.
A magnitude 1 earth-quack is 10000 times bigger than a magnitude -3 earth-quack. On the other hand, it is 1000000 times stronger in terms of energy release.
Note: To calculate the difference in energy between two earth-quacks, first you calculate the difference between their magnitudes and then you raise 10 to the output you obtain.
<u>Answer:</u>
Doubling time in reference to population is used to study the population growth. It projects the amount of time that the population will take to double in a particular region and it is calculated keeping in mind the annual growth rate of population of that area. This can be calculated by the rule of 70. But it is very rare that the doubling time remains the same for long and it is also rare that it changes drastically.
Answer:
As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts. The outer shell of the star, which is still mostly hydrogen, starts to expand. As it expands, it cools and glows red. The star has now reached the red giant phase. It is red because it is cooler than it was in the main sequence star stage and it is a giant because the outer shell has expanded outward. In the core of the red giant, helium fuses into carbon. All stars evolve the same way up to the red giant phase. The amount of mass a star has determines which of the following life cycle paths it will take from there.

The life cycle of a low mass star (left oval) and a high mass star (right oval).
the different evolutionary paths low-mass stars (like our Sun) and high-mass stars take after the red giant phase. For low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf.
Explanation:
Scientists choose to collect the smog at four different locations to allow them assess the smog from different region.
<h3>What is the role of Smog Collectors?</h3>
These are professional that examines scientific data that was collected by people on smog to assess the air we breathe.
Therefore, the scientists choose to collect the smog at four different locations to allow them access the smog from different region.
