If the magnetic lines of force intersected each other, then that would violate the laws of physics.
If the lines intersected, then at the point of
intersections there would be two directions of magnetic field force, and this cannot defy the laws of physics, so therefore it does not happen.
A good example of this would be if you had a
compass and you tried to use it to view the field direction. If you had two lines of force
intersecting, then the compass would have to
point in both directions, and that can't happen both theoretically and through observation.
An event like that would generate a monopole, which is an impossible, theoretical magnetic event.
Answer: Democritus
Explanation: Democritus was a Greek philosopher who was the first person to use the term atom(atomos: meaning indivisible). He thought that if you take a piece of matter and divide it and continue to divide it you will eventually come to a point where you could not divide it any more. This fundamental or basicunit was what Democritus called an atom.

Answer:
D) The carbon in the carboxylic acid is sp2 hybridized and has a higher percent s-character that shortens the C-O bond in the carboxylic acid.
Explanation:
The central carbon atom in acetic acid posses sp2 hybridization and the central carbon atom in ethanol posses sp3 hybridization. As the percent s-character in sp2 hybridized carbon atom is 33% whereas in sp3 hybridized carbon atom ther percent s-character is 25%. Higher is the s-character higher is the electronegativity and stronger is the tendency to pull shared pair of electron towards itself and thus, making the bond shorten and stronger. Thus, the carbon-oxygen single bond in acetic acid becomes short due to sp2 hybridization.
Therefore, option (D) is correct that the carbon in the carboxylic acid is sp2 hybridized and has a higher percent s-character that shortens the C-O bond.
