The ratio of 10kg to 100kg is 1:10

Two metal spheres are falling through a liquid of density 2xx10^(3)kg//m^(3) with the same uniform speed. The material density of sphere 1 and sphere 2 are 8xx10^(3)kg//m^(3) and 11xx10^(3)kg//m^(3) respectively. The ratio of their radii is :-

From the fixed pulley, masses 2 kg, 1 kg and 3 kg are suspended as shown is figure. Find the extension in the spring when acceleration of 3 kg and 1 kg is same if spring constant of the spring k = 100 N/m. (Take g = 10 ms^(-2) )

How much CO is produced by the reaction of 1.0 kg octane and 1.0 kg oxygen. Also report the limiting reagent for this reaction.

At 100^(@)C the volume of 1 kg of water is 10^(-3) m^(3) and volume of 1 kg of steam at normal pressure is 1.671 m^(3) . The latent heat of steam is 2.3 xx 10^(6) J//kg and the normal pressure is 10^(5) N//m^(2) . If 5 kg of water at 100^(@)C is converted into steam, the increase in the internal energy of water in this process will be
