Question
A question is given, followed by two statements
numbered (I) and (II). You have to decide whether the data provided in the statements is sufficient to answer the question. Read both the statements and select the appropriate answer. Question: Seven persons R, S, T, U, V, W and X are standing in a row and facing north direction but not necessarily in the same order. Who sits fourth to the right of U? Statements: (I) S sits second from one of the ends. Two persons sit between S and T. One person sits between V and U. V sits second to the left of T. (II) R sits immediate left of W. X sits second to the right of S. U sits immediate left of S. X sits to the right of V.Solution
From statement I alone, S sits second from one of the ends. Two persons sit between S and T. One person sits between V and U. V sits second to the left of T U S V _____T __________ Hence the statement I alone is sufficient to answer the question. From statement II alone, R sits immediate left of W. X sits second to the right of S. U sits immediate left of S. X sits to the right of V. We cannot fix the position. Hence the statement II alone is not sufficient to answer the question.

What is inertia?
A particle is projected such that its velocity vector sweeps equal angles with horizontal at equal time intervals. The motion is best described as:
