Scientific theories are explanations for naturally occurring events or phenomena. Although scientific theories require extensive

observations and experimentation, they can change over time as new evidence is discovered.
Scientific laws are principles that are also based on extensive observations and experimentation. Although scientific theories can develop into laws, a theory can only be declared a law if it is proven to be without exception under certain stated conditions.

Which of the following is true regarding scientific theories,laws, and knowledge?
A.
New scientific knowledge is gained by memorizing scientific theories and laws.

B.
Scientific theories and laws develop from the acquisition of scientific knowledge.

C.
Scientific theories can lead to scientific knowledge, but scientific theories are not related to scientific knowledge.

D.
Scientific knowledge must be proven by both scientific theories and laws.

The solid rod shown has a radius of 0.75 in. if it is subjected to the force the 500lb determine the max normal stress developed
Kipish [7]
The normal stress follows the formula written below:

σ = F/A

There are two types of stress, axial and tangential. Since we are only given with the dimension of the radius (and not the length), the possible stress is axial. So, the area is,

A = πr² = π(0.75 in)² = 1.767 in²

So,
σ = F/A = 500 lb/1.767 in² = <em>282.94 psi</em>

If the pH of a solution decrease's, is the solution getting more acidic or lees acidic
enyata [817]

Answer:

The solution becomes more acidic.

Explanation:

As the pH of a solution decreases, the concentration of hydrogen ions [H+] increases. Acidic solutions have a higher concentration of hydrogen ions and a lower pH.

I hope this helped. :)

SOMONE PLEASE HELP ASAP!!!!

Answer:

from vacuum to air

Explanation:

Refraction is a property of lightwave, in which it changes speed as it passes the boundary between two media.

  • When light travels from a denser medium to a less dense medium, the light wave speeds up and bends away from the normal.
  • Also when light travels from a less dense medium to a denser medium, the light wave slows down and bends toward the normal.

The correct option must be from a less dense medium to a denser medium.

density of glass = 2500 kg/m³

density of air = 1.275 kg/m³

density of ice = 919 kg/m³

density of water = 1000 kg/m³

density of plastic = 940 kg/m³

density of vacuum = 6.5 x 10⁻²⁷ kg/m³

The two possible options are;

from ice to water

from vacuum to air

The difference in densities of ice and water is not larger compared to vacuum and air.

If you are required to choose two options, the two options are correct

But if it is only one option, then from vacuum to air is the correct answer.

Therefore, the correct option is from vacuum to air
