Name two bacteria who can transform `N_2` from complex dead organic matter into `NO_3` salt and `NO_3` salt from soil to `N_2` gas in nature.

Identify the microbe that transfer N_2 to the environment from soil-

Certain bacteria living in the soil poor in oxygen convert nitrates into nitrites and then to free nitrogen and such bacteria are termed as Or The bacteria which convert NO_(3) rarr Free N_(2) are called as

(1) Show that the sum of energies for the transition from n=3 to n=2 and from n=2 to n=1 is equal to the energy of transition from n=3 to n=1 in case of an H-atom. (2) Are wavelength and frequencies of the emitted spectrum also additive as their energies?

Plants absorb sulphur in the form of 1. SO_(4) from soil 2. SO_(2) from air 3. both (1) and (2) 4. SO_(3) from soil

Transformer is a device used to increase or decrease the voltage in the transmission line according to requirement, Generally the input line voltage is fed in a primary coil and the output line voltage is obtained from the terminals of another coil In an ideal transformer, the primary and secondary coils are linked is such a way that there is no loss of magnetic flux and electrical energy. In an ideal transformer, if the number of turns and input voltage across the terminals of the primary coils be N_1 and V_1 , then the output voltage at the two terminals of the secondary coil V_2=V_1.N_2/N_1 , where N_2 is the number of turns in the secondary coil . In the above mentioned transformer the input and output currents are respectively.

There are two bags each of which contains n balls. A man has to select an equal number of balls from both the bags. Prove that the number of ways in which a man can choose at least one ball from each bag is^(2n)C_n-1.

Most of the plants obtain nitrogen from the soil in the form of 1. nitrites and molecular nitrogen 2. nitrates and ammonium salts 3. nitrites and ammonium salts 4. hyponitrites and nitrates

Mention the property for which lithium is used to separate N_2 gas from a gas mixture?
