visual reference point

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..

In this, a member of the colony stimulates or informs the other members by showing certain visual acts like i) Worker honeybee informs the other workers of the colony about the direction and distance of food source by its dancing movements (also referred as waggle dance). i..

Refer the figure to answer the questions. (i). Are points K, E and F collinear? (ii). Are points A, L, D and B coplanar? => (i) yes (ii) no or (i) no (ii) no or (i) yes (ii) yes or (i) no (ii) yes..

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..

Electrostatic field lines help us visualize electric fields. Similarly, potential at various points in an electric field can be represented graphically by equipotential surface..

Curve Sketching - The graph of a given function gives a visual presentation of the behaviour of the function involving a study of symmetry, rise and fall, region of existence, passage through specific points etc. The following points are helpful to trace the curv..

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..
