Karl Marx's 'Das Kapital' is a fundamental text in materialist philosophy and economics.

This emphasizes the fundamental dependence: without people, organizations would disappear. Despite technology and automation, people remain essential - they create, operate, innovate, and sustain organizations. The relationship is one of mutual dependence.

The textbook classifies human communication into two broad types:

• Intra-personal communication: “The part of communication in which self of a human being is involved only and the communication is confined to one human entity. This means that all the elements which come into action in a given piece of communication are located within the self of an individual. A message originating from source part of the brain travels through the channel of nerves to reach another location, however close it may be to the point of origin.” Examples: thinking, reasoning, meditation, monologue, and dreaming.
• Inter-personal communication: Involves two or more individuals, and is further classified into interpersonal (one-to-one), group communication, organisational communication, and mass communication.

The key distinguishing criterion is that in intra-personal communication, all elements — source, encoder, channel, decoder, and receiver — exist within the same person. No external communication partner is required.

For a body projected vertically upward, only gravity acts on it — a constant acceleration $g$ downward. From $v = u - gt$, velocity changes linearly with time, producing a straight line on a $v$-$t$ graph with slope $-g$.

Note that $10{,}000{,}000 = 10^7$.

Comparing $9^7$ vs $10^7$: since the base $9 < 10$ and both exponents are equal and positive, we have $9^7 < 10^7$.

Therefore Column B ($10^7$) is greater than Column A ($9^7$).
