single point of reference

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..

It is not possible to measure the absolute potential of a single electrode because neither the oxidation nor the reduction reaction can occur by itself. Also, we need two electrodes to measure the potential difference between two points. This difficulty can be solved selec..

Consider a parallel beam of light from a lens falling on a slit AB. As diffraction occurs, the pattern is focused on the screen XY with the help of lens L 2 . Each point on the unblocked portion of plane wavefront AB sends out secondary wavelets in all directions. The waves from ..

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..

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..

In these mutations one base pair is replaced by another. For e.g., - purine is replaced by pyrimidine (or) vice versa. The change in single base sequence causes silent mutation and non sense mutati..

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..
