On a voyage in their yacht,John and his father came across an iceberg. John advised his father to keep away from the iceberg. His father said that it is just a small piece of ice jutting out of the sea and there is nothing to bother. John told his father that icebergs are dangerous and narrated the story of the ship $Titanic$,which was sunk by an iceberg. John explained to his father why the iceberg was dangerous. This convinced his father,and they steered clear of the iceberg.

$(a)$ Why are icebergs in the sea dangerous?
$(b)$ What values are possessed by John and his father?
(N/A) An iceberg has a smaller density $(0.917 \text{ g cm}^{-3})$ than sea water at the same temperature. The density of sea water is about $1.018 \text{ g cm}^{-3}$,hence an iceberg floats with nearly $10\%$ of its volume outside the water. This means that only a small part of the iceberg is visible above the water surface,while the massive bulk remains hidden beneath,making it dangerous for ships.
$(b)$ John: Caring nature,awareness,and scientific knowledge.
John's father: Open-mindedness and respect for knowledge.
