Answer:
The scientific method may not follow the exact same steps each time because experiments are different. Some may have many more steps to follow to reach the conclusion, while others may take less time and have less steps. For example, some experiments may require a chart or graph of the results to be made, while others do not need that to display the results

Given the distribution of charges shown in this water molecule, why is it called "polar"?
Answer:
When a covalently bonded molecule has more electrons in one area than another, it is called a polar molecule. The electron cloud model can show an unequal sharing of electrons. ... This shows that electrons are more attracted to the oxygen end of the molecule than the hydrogen end, making the water molecule polar.
Answer:
Water (H2O) is polar due to the reality of the bent form of the molecule. The shape capability most of the terrible fee from the oxygen on facet of the molecule and the great price of the hydrogen atoms is on the one of a kind component of the molecule. This is an occasion of polar covalent chemical bonding.

As a star's size increases, its luminosity ___ as a star's temperature ___, its luminosity increases
1. is the first blank increases or decreases?
2. Is the second blank increases or decreases?
As a star's size increases, its luminosity increases as a star's temperature increases, its luminosity increases.
what is star luminosity ?luminosity is a calculated unit which means the energy produced by stars or galaxy , it is represent in the form of either joules per second or watts.
It generally depends on the size of the star that the lager sized star more energy it give, more luminous.
Secondly, the temperature of the star, if two same sized stars with different temperature, then higher temperature will be more luminous.
It is otherwise determined the actual measure of the absolute magnitude of the power output of the star.
It can be used to understand the stellar classification of various stars.
It can be used to predict the lifecycle of the star and helps astronomers.
luminosity is much more specific than brightness of the star as it is a mathematical calculation.
