How does accumpulation of varriation takes place |
|
Answer» All living organism reproduce. The offspring produced differ from parents.They inherit traits from parents as well as they develop new variations also. If the variations are useful in survival and reproduction they pass on to next generation resulting in more population having these variations.These variations accumulate and show changes in the population. This whole process explains the accumulation of variations Accumulation Of Variations During Reproduction. The variations accumulate and pass on to more and more individuals with each generation. The diversity is small in case of asexually reproducing organism as it is caused by only errors of DNA copying mechanism. |

Focal length of a convex mirror is 50cm . what is its radius of curvature? |
|
Answer» F= R/2 50=R/2 = 100 Thnx 100 cm |
|
| 49088. |
What is relation between radius and centre of curvature. |
| Answer» The relationship between the focal length f and radius of curvature r is r = 2f.Consider a ray of light AB, parallel to the principal axis and incident on a spherical mirror at point B. The normal to the surface at point B is CB and CP = CB = R, is the radius of curvature. The ray AB, after reflection from mirror, will pass through F (concave mirror) or will appear to diverge from F (convex mirror) and obeys the law of reflection i.e. i = r.From the geometry of the figure,∠BCP = θ = iIn D CBF, θ = r∴BF = FC (because i = r)If the aperture of the mirror is small, B lies close to P, and therefore BF = PFOr FC = FP = PFOr PC = PF + FC = PF + PFOr R = 2 PF = 2fOr f = R/2Similar relation holds for convex mirror also. In deriving this relation, we have assumed that the aperture of the mirror is small. | |

Why voltmeter is always connected in parallel series |
|
Answer» I don\'t know Because voltmeter has high resistance. A voltmeter is a device which measures voltage across a resistor. If it is connected in series, then there would be some voltage drop across the voltmeter itself and hence, would not record the correct voltage across the resistor. Because to know the potential diff between two points it needs to be connected to two points on a circuit, which can only be accomplished by parallel connection. If it if connected in series, it will not work the way its supposed to. It will give the potential difference as 0. |
