Cohesion refers to attraction between molecules of the same kind while adhesion refers to attraction between different kinds of molecules

A SIPO and AND gate circuit can detect this sequence.The output of SIPO is connected to a four input AND gate ,the third SIPO output should be connected through a NOT gate.When the 1101 sequence is loaded in to the SIPO the AND output goes HIGH otherwise keeps LOW.

Electronegativity is the tendency for an atom to attract electrons. There are general trends on the periodic table which you can use to determine the relative electronegativity for different elements, but otherwise you can also look at their valence shell and effective nuclear charge to determine their relative electronegativity.

Here from the given options, Lithium has least tendency to attract electrons and thus has a lower electronegativity.

The absence of a landmass within these latitudes in the southern hemisphere eliminate friction and lends force to these winds and hence derives the name
