in this example, we are given that a thermodynamic system, internal energy of, system decreases by 400 joule. while it is doing 2 50 joule of work. we are required to find what net heat is taken in, by the system in the process we need to find out the amount of heat supplied, here

let us now discuss the use of bohr model to define hypothetical energy levels in different kind of imaginary atom , if we talk about hydrogenic atoms we can directly write that – in hydrogenic atoms . bohr’s first and second postulates . are given as. we know that bohr’s first postulate is given in

let us study about some characteristic definitions about spherical mirrors. like we are studied that there are 2 types of spherical mirrors, one is a concave mirror. in which the outer surface is polished and the inner surface is reflecting. in this situation. the mid point of the. mirror piece. which is, a section of
