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..

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..

Choose the translated coordinates of a point P in a plane when the origin O is shifted to the point O' ( h , k ) without changing the direction of the axes, where ( x , y ) and ( x ′, y ′) are the coordinates of the point P referred to original an..

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 referred to as the CO..

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 ..

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 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..

Rest and motion are relative terms. A person sitting in a moving car is at rest with respect to his or her fellow passengers, but is in motion with respect to other objects or people on the road. Moreover, it is not possible to define 'absolute rest' or 'absolute motion'. Absolute rest is the compl..

Question: Why are the two non-metals, carbon and hydrogen are important chemical reference points with regard to the method of metal extraction and reactivity towards acids. Answer: The six metals K, Na, Li, Ca, Mg, and Al, which lie above carbon in the activity serie..
