Three conducting rods of same material and crosssection are shown in figure. Temperature of A, D and C are maintained at \(20^{\circ} \mathrm{C}, 90^{\circ} \mathrm{C}\) and \(0^{\circ} \mathrm{C}\). The ratio of lengths of \(B D\) and \(B C\) if there is no heat flow in \(A B\) is: 
263854 Given below are two statements: Assertion I: The Bohr model is applicable to hydrogenic atoms. It cannot be extended to even two electron atoms such as helium Reason II: The formulation of Bohr model involves electrical force between positively charged nucleus and electron. It does not include the electrical forces between electrons which necessarily appear in multi-electron atoms. In the light of the above statements, choose the most appropriate answer from the options given below :
263855 Given below are two statements: Statement I: The nuclear force does not distinguish between neutron and proton. Statement II : Energy associated with nuclear processes are about a million times larger than chemical process.
