    A vertical pipe at both ends is partially submerged in water. A tuning fork of unknown frequency is placed near the top of the pipe and made to vibrate. The pipe can be moved up and down and thus length of air column in the pipe, standing waves will be setup as a result of directions. Smallest value of length of air column, for which sound intensity is maximum, is 10 cm. (take speed of sound, v = 344 m/s] The air column here is closed at one end because the surface of water acts as a wall. Which of the following is correct ?

    According to V.B.T. a covalent bond is formed by the overlapping of half filled atomic orbitals with electron spinning in the opposite direction. The strength of a bond depends on extent of overlapping. Double bond energy is not twice that of single bond energy because a double bond is made up of a weak a bond and strong o bond. According to V.B.T, in the formation of CH_4 molecule the type of overlappings observed are
