IIT JAM Physics Last year Question paper
Can you Give me question papers for IIT JAM joint admission test physics subject as soon as possible ? Here I am giving you question papers for IIT JAM joint admission test physics subject in PDF file attached with it so you can get it easily. A lightly damped harmonic oscillator loses energy at the rate of 1% per minute. The decrease in amplitude of the oscillator per minute will be closest to (A) 0.5% (B) 1% (C) 1.5% (D) 2% A parallel plate air-gap capacitor is made up of two plates of area 10 cm2 each kept at a distance of 0.88 mm. A sine wave of amplitude 10 V and frequency 50 Hz is applied across the capacitor as shown in the figure. The amplitude of the displacement current density (in mA/m2) between the plates will be closest to (A) 0.03 (B) 0.30 (C) 3.00 (D) 30.00 A tiny dust particle of mass 1.4 ×10-11 kg is floating in air at 300 K. Ignoring gravity, its rms speed (in µm/s) due to random collisions with air molecules will be closest to (A) 0.3 (B) 3 (C) 30 (D) 300 When the temperature of a blackbody is doubled, the maximum value of its spectral energy density, with respect to that at initial temperature, would become Q.8 (A) 116 times (B) 8 times (C) 16 times (D) 32 times Light takes 4 hours to cover the distance from Sun to Neptune. If you travel in a spaceship at a speed 0.99c (where c is the speed of light in vacuum), the time (in minutes) required to cover the same distance measured with a clock on the spaceship will be approximately (A) 34 (B) 56 (C) 85 (D) 144 6027Co is a radioactive nucleus of half-life 2ln2×108 s. The activity of 10g of in disintegrations per second is 6027Co Q.10 (A) 15 ×1010 (B) 5 ×1010 (C) 15 ×1014 (D) 5 ×1014 IIT JAM Physics Last year Question paper Last edited by Neelurk; February 15th, 2020 at 02:45 PM. |
