Which of the following velocity-time graph is showing motion of a particle with negative acceleration? निम्न में से कौनसा वेग-समय आरेख ऋणात्मक त्वरण से एक कण की गति को दर्शाता है?
The correct statement with regard to H+2 & H−2 is
Assertion : For drying H2S, Conc. H2SO4 cannot be used.
Reason: Moist H2S is oxidized by Conc.H2SO4
Two block of wood of masses m1and m2 and each of specific gravity 0.5 are submerged at a depth of h1 and h2 in a vessel (h2>h1) filled with water, which is accelerated upwards with an acceleration g2. the difference in time taken by the blocks to reach the surface, when released with zero velocity is :
