27 – Ans: A. A node, which is represented by a
point in the diagram, is always formed at the closed end of the pipe [So, D is
incorrect] and an antinode is always formed at the open end of the pipe [So, C
is incorrect]. At a node, the direction of motion changes [since if we consider
the graph, the displacement before/after the node may be in one direction and
the other displacement after/before the node is in another direction] So, B is
incorrect and A is correct.
30 - Ans: B. {Detailed explanations for this question is available as Solution 929 at Physics 9702 Doubts | Help Page 191 - http://physics-ref.blogspot.com/2015/08/physics-9702-doubts-help-page-191.html}
