KVPY Solutions By Resonance
Can you please provide here solved question paper of Kishore Vaigyanik Protsahan Yojna (KVPY) aptitude test ? As you requires I am here giving you solved question paper of Kishore Vaigyanik Protsahan Yojna (KVPY) aptitude test . KVPY Aptitude Test Paper A box, when hung from a spring balance shows a reading of 50 kg. If the same box is hung from the same spring balance inside an evacuated chamber, the reading on the scale will be (A) 50 kg because the mass of the box remains unchanged (B) 50 kg because the effect of the absence of the atmosphere will be indentical on the box and the spring balance (C) Less than 50 kg because the weight of the column of air on the box will be absent (D) More than 50 kg because the atmospheric buoyancy force will be absent Two possitively charged spheres of masses m1, and m2, are suspended from a common point at the ceiling by identical insulating massless strings of length l. Charges on the two spheres are q1 and q2, respectively. At equilivrium both strings make the same angle q with the vertical. Then (A) q1m1 = q2m2 (B) m1 = m2 (C) m1 = m2sin q (D) q2m1 = q1m2. A thin paper cup filled with water does not catch fire when placed over a flame. This is because (A) The water cuts off oxygen supply to the paper cup (B) Water is an excellent conductor of heat (C) The paper cup does not become appreciably hotter than the water it contain (D) Paper is a poor conductor of heat Ice is used in a cooler in order to cool its contents. Which of the following will speed up the cooling process (A) Wrap the ice in a metal foil (B) Drain the water from the cooler periodically (C) Put the ice as a single block (D) Crush the ice Two equal charges of magnitude Q each are placed at a dictance d apart. Their electrostatic energy is E. A third charge -Q/2 is brough midway betway these two charges.The electrostatic energy of the system is now (A) -2E (B) -E (C) 0 (D) E A bar magnet falls with its north pole pointing down through the axis of a copper ring. When viewed from above, the currecnt in the ring will be (A) Clockwise while the magnet is above the plane of the ring and counter clockwise while below the plane of the ring (B) Counter clockwise throughout (C) Counter clockwise while the magnet is above the plane of the ring, and clockwise while below the plane of the ring (D) Clockwise throughout. In 1911, the physicist Ernest Rutherford discovered that atoms have a tiny, dense nucleus by shooting pisitively charged particles at a very thin gold foil. A key physical property which led Rutherford to use gold that it was (A) Electrically conducting (B) Highly malleable (C) Shiny (D) none-reactive Consider the following statements (i) All isotopes of an element have the same number of neutrons (ii) Only one isotope of an element can be stable and non-radioactive (iii) All elements have isotops (iv) All isotopes of Carbon can form chemical compounds with Oxygen-16 The correct option regarding an isotope is (A) (iii) and (iv) only (B) (ii), (iii) and (iii) only (C) (i), (ii) and (iii) only (D) (i), (iii) and (iv) only Here is the attachment KVPY-Stream-SA-Solved-Paper Last edited by Neelurk; April 2nd, 2020 at 04:03 PM. |
