Re: WBJEE Question
Here I am providing the list of few questions of West Bengal Joint Entrance Examination (WBJEE) Physics & Chemistry exam question paper which you are looking for . A whistle whose air column is open at both ends has a fundamental frequency of 5100 Hz. If the speed of sound in air is 340 ms–1, the length of the whistle, in cm, is (A) 5/3 (B) 10/3 (C) 5 (D) 20/3 Ans : (B) 2. One mole of an ideal monoatomic gas is heated at a constant pressure from 0°C to 100°C. Then the change in the internal energy of the gas is (Given R = 8.32 Jmol–1K–1) (A) 0.83 × 103 J (B) 4.6 × 103 J (C) 2.08 × 103 J (D) 1.25 × 103 J To determine the coefficient of friction between a rough surface and a block, the surface is kept inclined at 45° and the block is released from rest. The block takes a time t in moving a distance d.The rough surface is then replaced by a smooth surface and the same experiment is repeated. The block now takes a time t/2 in moving down the same distance d. The coefficient of frict on is (A) 3/4 (B) 5/4 (C) 1/2 (D) 1/ 2 West Bengal Joint Entrance Examination Physics & Chemistry exam question paper For the question paper , here is the attachment; |
