Two liquids of equal mass and different densities`p_1` and `p_2`are mixed, what is the density of the mixture?

If the density of pure water is 1g/ml then what is the molarity of water?

Two solid spheres of the same mass are made of metals of different densities. Which of them has a larger moment of inertia about a diameter?

Two satellites of equal masses, which can be considered as particles, are orbiting the earth at different heights. Will their moments of inertia be same or different?

What is the difference between electric current and electric current density?

Estimate the average mass density of a sodium atom assuming its size to be about 2.5 A- (Use the known values of Avogadro’s number and the atomic mass of sodium). Compare it with the density of sodium in its crystalline phase: 970 kg m^(-3) . Are the two densities of the same order of magnitude? If so, why

The unit of length convenient on the nuclear scale is a fermi : 1 f = 10^(-15) m. Nuclear sizes obey roughly the following empirical relation : r = r_0A^(1/3) where r is the radius of the nucleus, A its mass number, and r_0 is a constant equal to about, 1.2 f. Show that the rule implies that nuclear mass density is nearly constant for different nuclei. Estimate the mass density of sodium nucleus. Compare it with the average mass density of a sodium atom obtained in Exercise. 2.27.

The temperature of equal masses of three liquids A,B and C are 12°C,19°C and 28°C respectively.The temperature ,when A and B are mixed is 16°C and when B and C are mixed ,it is 23°C .What will be temperature when A and C are mixed.
