Which statement describes a scientific theory?

2 answers:

7 0

Best Answer
C) is the best description, although a scientific theory is not necessarily a "fact". They are, however, based on evidence.

A) is complete garbage.

B) is a good description of a scientific "law"- something that predicts how a certain event will occur without explaining why this is (for instance, the law of gravity accurately describes the gravitational forces between two bodies, but does not explain why these forces are there).

D) is a scientific "hypothesis"- an explanation for an observed phenomena that is yet to be proven.

The correct statement is C) A theory changes based on new observations and testing.

<h3>FURTHER EXPLANATION</h3>

A) A theory states how something behaves without explaining why.

FALSE because a theory is actually a statement that explains why an observed phenomenon happens. A statement or an observation of how something behaves without explanation is a scientific law, not a theory.

B) A theory is a proven fact that cannot be changed.

FALSE because a theory may be changed or proven false if new evidence that contradicts or debunks the existing theory comes to light. An example is the development from Classical Mechanics to Special Relativity to the Theory of General Relativity with each subsequent theory providing explanations to situations the preceding could not.

C) A theory changes based on new observations and testing.

TRUE because a theory is only valid when a lot of data support it. If new observations challenge the theory, then it may be changed or abandoned.

D) A theory is based on a single hypothesis or observation.

FALSE because a theory is considered as the best explanation for a phenomenon so far. For it to be considered the “best” it has to have been peer-reviewed and repeatedly tested and verified by the scientific community.

The dessert can be harsh environment with extreme heat during the day and cold during the night also there is very little rainfa

Sphinxa [80]

Answer:

True

Explanation:

The desert refers to a region of arid land which is characterized by extreme temperatures, extreme dryness, low amount of precipitation and generally harsh living conditions. Because of these harsh conditions, they have been tagged with various names ranging from 'Death Valley' to 'the place from where there is no return' etc.

Every desert is made up of 2 components: the <u>biotic (living) component</u> and the <u>abiotic (non-living) component</u>. The biotic (living) component consists of the plants and animals that have adapted to these harsh living conditions e.g. Cactus or Cacti, Holly plants, Camels, Lizards, Snakes etc. The abiotic (non-living) component consists of climate (subtropical deserts which are extremely cold or temperate deserts which are extremely hot), location, precipitation/rainfall

What is the graph that represents the relation between durability of titanium and temperature ?

matrenka [14]

The downward slope represents the relation between durability of titanium and temperature because with increase temperature, strength of titanium decreases.

<h3>Can titanium withstand temperatures?</h3>

Titanium alloys have high tensile strength to weight ratio, good toughness and an ability to bear extreme temperatures of more than 600 °Celsius. This shows that if temperature increase from more than 600 °Celsius, the strength of the titanium tends to decrease because it can not withstand to it so the graph comes to downward when the temperature exceeds to 600°C.

So we can conclude that the downward slope represents the relation between durability of titanium and temperature because with increase temperature, strength of titanium decreases.

The radius of an indium atom is 0.163 nm. If indium crystallizes in a face-centered unit cell, what is the length of an edge of

adoni [48]

<u>Answer:</u> The edge length of the unit cell is 0.461 nm

<u>Explanation:</u>

We are given:

Atomic radius of iridium = 0.163 nm

To calculate the edge length, we use the relation between the radius and edge length for FCC lattice:

$a=2\sqrt{2}R$

Putting values in above equation, we get:

$a=2\sqrt{2}\times 0.163=0.461nm$

Hence, the edge length of the unit cell is 0.461 nm
