a) Positions of the antinodes
Consider the positions, where Since the resultant amplitude R is maximum, these points correspond to the antinodes. It may be noted that the antinodes correspond to i.e., zero strain. Thus, antinodes are obtained at those points corresponding t..

The existence of negative and positive charges on these materials can be explained on the basis of the structure of the atom. Almost all the mass of an atom resides in a central nucleus which contains a number of tightly packed protons and neutron..

Solution
In diamond, all the four valencies of each carbon atom are satisfied by bonding to other carbon atoms through regular covalent bonds. The electrons are held tightly between the nuclei, and there are no mobile electrons. Thus diamond structure is a closely packed structure and is extremel..
Solid
The molecules in a solid are very closely packed. The inter-molecular force of attraction is very strong in solids. Hence solids have a definite size and shape. Molecules of a solid vibrate about their mean position. Molecular structure of a solid Solids cannot be compresse..

In diamond, the carbon atoms are arranged tetrahedrally (sp 3 hybridisation of C): each C atom is linked to its neighbors by four single covalent bonds. This leads to a three-dimensional network of covalent bonds...

The vascular tissue system is a derivative of procambium. It is represented by the conducting tissues-xylem and phloem. These vascular tissues occur in the form of strands extending from one end of the plant body to another. These strands are known as vascular bundles or fascicles. In the leaf, the..
Hydrogen Bonding in Water and Ice
>As a result of tetrahedral arrangement of H 2 O molecules in the solid state, the ice structure extends in three dimensions. Further the molecules of H 2 O are not packed closely as hydrogen bonds between oxygen and H atoms are longer than covalent bonds between them. This results in vac..
Median canal
( Scala media ) It is the central canal formed by longitudinal membranes present along the length of the cochlea. It is filled with endolymph. The dorsal membrane is called the Reissner's membrane and the ventral membrane is called the basilar membrane. The median canal has the organ of Corti whe..

Each ovule is attached to the placenta by a stalk called funicle. The body of the ovule fuses with the funicle to form the hilum in the seed. The ovule consists of one or two integuments, accordingly the ovules are called unitegmic or bitegmic respectively. The integuments leave a small openi..
