Re: Aipmt Sample Test Papers
The previous year question paper for National Eligibility cum Entrance Test Under Graduation or NEET UG is as follows: The fundamental frequency in an open organ pipe is equal to the third harmonic of a closed organ pipe. If the length of the closed organ pipe is 20 cm, the length of the open organ pipe is (1)12•5 cm (2)8 cm (3)13•2 cm (4)16 cm The efficiency of an ideal heat engine working between the freezing point and boiling point of water, is (1)6•25% (2)20% (3)26•8% (4)12•5% A set of ‘n’ equal resistors, of value ‘R’ each, are connected in series to a battery of emf ‘E’ and internal resistance ‘R’. The current drawn is I. Now, the ‘n’ resistors are connected in parallel to the same battery. Then the current drawn from battery becomes 10 I. The value of ‘n’ is (1)20 (2)11 (3)10 (4)9 An astronomical refracting telescope will have large angular magnification and high angular resolution, when it has an objective lens of (1)large focal length and large diameter (2)large focal length and small diameter (3)small focal length and large diameter (4)small focal length and small diameter For a radioactive material, half-life is 10 minutes. If initially there are 600 number of nuclei, the time taken (in minutes) for the disintegration of 450 nuclei is (1)30 (2)10 (3)20 (4)15 Question Paper National Eligibility cum Entrance Test Under Graduation or NEET UG |
