Source based/case based question
37. Mr. Vijay a farmer from a village in India decided to start cattle farming to boost his family's income.
He chose Red Sindhi cattle for their ability to adapt to the local environment. Mr. Vijay focused on both
draught and milk animals.
To improve milk production, he applied a cross breeding technique using both Indian and exotic cattle
breeds. He ensured the cattle received a proper diet and followed a regular vaccination schedule to
protect them from diseases. Mr. Vijay's aim was to improve the productivity of his farm.
Answer the following questions based on the above case.
i)What are draught and milk animals?
ii) Name one exotic and one Indian breed of cattle.
ii)What is cross-breeding?

39. Rutherford's model of atom: The model of atom was given by Rutherford. According to him cach atom
has tiny core at its centre which is called nucleus of the atom. In the nucleus whole mass and positive
charge of the nucleus is concentrated. The nucleus of the atom is surrounded by a number of electrons.
But whole atom is electrically neutral. These electrons revolve in certain orbits around the nucleus of an
atom the electrons get centripetal force from the electrostatic force between nucleus and electrons.
Answers the following questions based on the above case.
(a) On the basis of Rutherford model of an atom, which subatomic particle is present in the nucleus of
an atom?
(b) Why Rutherford used only gold foil not any other metal foil?
(c) According to the Rutherford model of an atom where is the positive charge concentrated in an atom.
(d) What does nucleus consist of?
