A park is in the shape of a circle of radius 8 m . It was designed to have a circular rose garden at the center of the park, concentric with the park with a radius of 4 m . Find the area of the park available for other plantations in square meters. => 12 π or 80 &pi..

Photoperiodism - W. W. Garner and H. A. Allards work on Maryland Mammoth, a variety of tobacco and Glycine max established the fact that it was the length of the day, which controlled flowering in these plants. Garner and Allard suggested the term photoperiodism to designate the..

Q stands for quality. The voltage magnification produced by series resonance is termed as Q-factor of the series resonance circui..

Erosion of soil can be due to action of water or air. Erosion of soil by water can be prevented by i) Checking of overgrazing and stopping the cutting down of forests. ii) Terracing of sloping lands reduces the speed of water and prevents soil erosion. iii) Bunds around the fields checks the ..

The following passage has not been edited. There is an error in each line against which there is a blank. Underline each error and write your correction in the space provided. I entered the manager's office and sat down. I have just lost five hundred rupees and I felt very upset. a) ______ "I..

According to LCAO method, the orbitals are formed by the linear combination (addition or subtraction) of atomic orbitals of the atoms, which form the molecule. This theory is applicable to hydrogen molecule as follows. Consider that hydrogen molecule consists of two atoms A and B. Each of these ato..

The relative energies of molecular orbitals depend upon the following two factors: (i) the energies of the atomic orbitals combining to form molecular orbitals. (ii) the extent of overlapping between the atomic orbitals. The greater the overlap, the more the bonding orbital is lowered and the ..

Energy Level Diagram for Molecular Orbitals - The relative energies of molecular orbitals depend upon the following two factors: (i) the energies of the atomic orbitals combining to form molecular orbitals. (ii) the extent of overlapping between the atomic orbitals. The greater the overlap, th..

Space Launching Vehicles - To place a satellite into orbit it needs to be accelerated in several stages. The required acceleration is produced by firing rockets at various stages of flight. These rockets are fitted into a system called 'launch vehicle' which carries the satellite. By firing rockets..

Orientation of d-orbitals and Crystal Field Splitting - The five d-orbitals can be divided into two groups depending upon the nature of their orientation in space. (i) The three d-orbitals (d x y , d y z , d z x ) which orient in the regions in between the coordinate axes are designated..
