Answer:

<em>The correct option is theories. </em>

Explanation:

A scientific theory is a detailed explanation of natural researches which are supported through evidence. Scientific theories can be changed if other evidence are made which support another theory. Hence, scientific theories can change. The concepts of plate tectonics and evolution change overtime whenever new pieces of evidence are discovered. Hence, they are scientific theories.

Other options such as hypotheses are not correct because a hypothesis is just a tentative statement which can either be proved to be correct or wrong. Observations are not made on evidences hence the option observations is also not correct.

4x+28=2x+24+2x+2 slove for x
Alinara [238K]

The answer you are looking for is x = 0 (or undefined)

To solve for x, you would first combine all the like terms on the right side. To do so, add 2x and 2x to get 4x and add 24 and 2 together to get 26. This will give you 4x + 28 = 4x + 26, which you can now solve.

To find x, you would get the x by itself. However, in doing so you would get 0 or 0x. This is because you would subtract 4x on both sides to cancel out the 4x on the right, but in this case, it will also cancel out the 4x on the left. Thus meaning the answer is 0 or undefined.

I hope this helps!

Mercury in a box have density is 30000kg/m^3 height is 20 dm. Determine the pressure of Mercury .​
Musya8 [376]

Answer:The pressure of Mercury = 588,600Pa

Explanation:

The pressure of Mercury is given as

p=h x ρ x g

Where h =height= 20 dm

changing to meters

10 decimeters (dm) =1 meter

20dm  =2 meter, 2m

ρ  is the density =30000-kg/m³

g , gravity = 9.81-m/s²  

Pressure =  2.0m x 30000-kg/m³ x 9.81-m/s²

588,600 kg.m/  s²/m² =588,600 N/m²

The pressure of Mercury=588,600Pa
