Out of the given statements, Science consists of proven theories that are understood to be true explanations of reality is not consistent with the major hallmarks of science.
Answer: Option A
<u>Explanation:
</u>
Hallmarks of science are the factors that need to be logically acceptable about any given theory for it to be called 'scientific'. These hallmarks are specific, nor absolute neither relative in nature.
For a theory to qualify scientific hallmarks, it can also be at the stage of a proposed hypothesis, not necessarily a true explanation of true reality. For example, the theory of relativity was still considered a scientific theory before Albert Einstein proved it to be true.
Answer:
<em>See explanation</em>
Explanation:
Given
Represent the vertical angle with 
The question has incomplete details because the length of the ladder is not given; neither is the distance between the ladder and the wall given.
<em>See attachment for illustration</em>
So, this solution will be based on assumptions.
Represent
- The height from ground to the top of the ladder with y
- The length of the ladder with L
- The distance between the ladder and the wall with x
Carla could solve for y in any of the following ways:
1. Tan formula
In this case:
Multiply both sides by y
Divide both sides by tan
This can be used if the distance (x) between the ladder and the wall is known.
Assume x = 15
2. Cosine formula
In this case:
Multiply both sides by L
This can be used if the length (L) of the ladder is known.
Assume L = 15
Answer:
Greece's steep mountains and surrounding seas forced Greeks to settle in isolated communities. Travel by land was hard, and sea voyages were hazardous. Most ancient Greeks farmed, but good land and water were scarce. ... Many ancient Greeks sailed across the sea to found colonies that helped spread Greek culture.
Explanation:
Answer: The correct options are:
<em>exerts more pressure as it increases
</em>
<em>measures how tightly molecules are packed
</em>
<em>equals mass divided by volume</em>
Explanation:
Air density can be described as mass per unit of volume of the volume of air.
As the altitude increases, the air density tens to decrease. Hence, option A is not correct.
The density of the air determined how many atoms of air can occur in a particular volume, In other words, it determines how tightly or loosely atoms of air are packed in a particular volume.
Hence, when the air density will increase, the molecules will be more tightly packed and the pressure will be more.
