The above figure shows a body moving with uniform speed along a circle. Let perpendiculars be drawn from different positions of the body onto any diameter, say the vertical diame..

Refer to the figure shown. Choose the correct statement. => DE = 1 2 × EF or DE = DE + EF or DE = EF or DE = 2 × EF..

The timing or position of the pulse is varied around a fixed mean value and conforms to the signal amplitude at the time of sampling. A positive signal may set the pulse ahead, a negative signal will set the pulse behind the reference time. In reception, the..

It is the time taken by the particle executing SHM, to complete one oscillation i.e., a to and fro motion. It will be equal to the time taken by the body to complete one revolution or the circle of reference..

Ecosystem - Structure and Function - The characteristic structure of an ecosystem is obtained by the systematic physical organisation of the abiotic and biotic components of that particular ecosystem. The two main structural features of any ecosystem are its 'species composition' and 'stratificatio..

Misuse of natural resources refers to excessive use, destructive use or achieving imbalance between resources either individually or in combination. Misuse of resources can also be direct or indirect. Direct misuse refers to such situations where the resource is directly destroy..

It refers to artificial propagation of plants vegetatively through the culture of cell or tissue. It is most useful, when normal propagation takes long time or the success in fertilization is very poor as seen in many valuable plants useful in agriculture, horticulture and..

Micropropagation - It refers to artificial propagation of plants vegetatively through the culture of cell or tissue. It is most useful, when normal propagation takes long time or the success in fertilization is very poor as seen in many valuable plants useful in agriculture, hor..
