In law and ethics, universal law or universal principle refers as concepts of legal legitimacy actions, whereby those principles and rules for governing human beings' conduct which are most universal in their acceptability, their applicability, translation, and philosophical basis, are therefore considered to be most ...

The best answer is (B) Which it effects at all times.

(That’s what I got for my test btw)

Laws of nature as expressed in physics as laws and theories are often said to be universal. This means that, so far as we have been able to test them, they apply everywhere and at every time, past, present and future.

Explanation: A scientific theory is usually proposed to explain certain observations after repeated experiments and available facts. However, a scientific law is more experimented and confirmed than scientific theories - this means scientific law is better supported by scientific facts and data than scientific theory.

Answer from: Quest

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

Answer from: Quest

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
