The Circle of Reference - 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 the figure to answer the questions. (i). Are the points B, C and D collinear? (ii). Name any one plane. => (i) yes (ii) plane BAD or (i) yes (ii) plane BDE or (i) no (ii) plane EGF or (i) no (ii) no planes in the figure..

Coordinates - The coordinates of a point are quantities, which determine the position of the point. If for instance, a point P lies somewhere on a straight line XX', then its position may be defined by a single number in the following way: Choose some reference..

Compensation Point - At a given low concentration of CO 2 and non-limiting light intensity, the photosynthetic rate of a given plant will be equal to the total amount of respiration. The atmospheric concentration of CO 2 at which photosynthesis just compensates for respiration is ref..

Iso-electric Point - It is defined as the point at which a molecule exists as zwitter ion with no net charge. Thus, at this point the molecule is electrically neutral. The molecules have minimum solubility, maximum precipitability and least buffer capacity. The acidic ..

To devise a scale of temperature, fixed reference points (temperature) are required, with respect to which all other temperatures are measured. For both Celsius and Fahrenheit Scales of temperatures, the fixed points are as follo..

Displacement vector is a vector which gives the position of a point with reference to a point other than the origin of the coordinate syste..

The rays of light parallel to the principal axis of a mirror after reflection, either pass through a point (in the case of a concave mirror) or appear to diverge from a point (in the case of a convex mirror) on the principal axis and this point is referred t..

The first theory was called the Werner's theory of co-ordination compounds. 1) Metals possess two types of valencies: a) Primary valency or ionizable valency. It is also referred to oxidation state. b) Secondary valency which a metal atom or cation exercises towards neutral molecules or n..

The coordinates of a point are quantities, which determine the position of the point. If for instance, a point P lies somewhere on a straight line XX', then its position may be defined by a single number in the following way: Choose some reference pointh..
