The relative density of lead is 11.3. Its density is ....g cm–3 or ....kg m–3.
Here the relative density of lead is given. We have to find the density of lead.
Relative density of lead = -------------- (1)
Density of lead = Relative density of lead × Density of water
Relative density of lead = 11.3
Density of water = 1 g/cm3 = 1000 kg/m3
Substituting the above density values in equation (1).
Density of lead = 11.3 × 1 g/cm3
= 11.3 g/cm3
We have to find the density of lead in kg/m3 also.
Substituting the value of density of water in kg/m3 in equation (1)
Density of lead = 11.3 × 1000 kg/m3
= 1.13 × 104 kg/m3
The density of lead = 11.3 g/cm3 or 1.13 × 104 kg/m3

Einstein’s mass - energy relation emerging out of his famous theory of relativity relates mass (m ) to energy (E ) as E = mc2, where c is speed of light in vacuum. At the nuclear level, the magnitudes of energy are very small. The energy at nuclear level is usually measured in MeV, where 1 MeV= 1.6×10-13J; the masses are measured in unified atomic mass unit (u) where
1u = 1.67 × 10-27 kg.
(a) Show that the energy equivalent of 1 u is 931.5 MeV.
(b) A student writes the relation as 1 u = 931.5 MeV. The teacher points out that the relation is dimensionally incorrect. Write the correct relation.

(a) How many astronomical units (A.U.) make 1 parsec?
(b) Consider a sunlike star at a distance of 2 parsecs. When it is seen through a telescope with 100 magnification, what should be the angular size of the star? Sun appears to be (1/2)° fromthe earth. Due to atmospheric fluctuations, eye can’t resolve objects smaller than 1 arc minute.
(c) Mars has approximately half of the earth’s diameter. When it is closest to the earth it is at about 1/2 A.U. from the earth. Calculate what size it will appear when seen through the same telescope.
(Comment : This is to illustrate why a telescope can magnify planets but not stars.)

In an experiment to estimate the size of a molecule of oleic acid 1 mL of oleic acid is dissolved in 19 mL of alcohol. Then 1 mL of this solution is diluted to 20 mL by adding alcohol. Now 1 drop of this diluted solution is placed on water in a shallow trough. The solution spreads over the surface of water forming one molecule thick layer. Now, lycopodium powder is sprinkled evenly over the film and its diameter is measured. Knowing the volume of the drop and area of the film we can calculate the thickness of the film which will give us the size of oleic acid molecule.
Read the passage carefully and answer the following questions:
(a) Why do we dissolve oleic acid in alcohol?
(b) What is the role of lycopodium powder?
(c) What would be the volume of oleic acid in each mL of solution prepared?
(d) How will you calculate the volume of n drops of this solution of oleic acid?
(e) What will be the volume of oleic acid in one drop of this solution?

The Sun is a hot plasma (ionized matter) with its inner core at a temperature exceeding
107 K, and its outer surface at a temperature of about 6000 K. At these high temperatures, no substance remains in a solid or liquid phase. In what range do you expect the mass density of the Sun to be, in the range of densities of solids and liquids or gases? Check if your guess is correct from the following data: mass of the Sun = 2.0 ×1030 kg, radius of the Sun = 7.0 × 108 m.NCERT - Physics Part-I
