Calculate the power required by a force to turn a rigid body by some angle θ. |
|
Answer» Power in rotational motion is as in linear motion. derivation of Power to rotational motion can be obtained from Work and Kinetic Energy, the instantaneous power (or just power) is defined as the rate of doing work P = dW / dt If we have a net torque then W = τθ and the power is P = dW / dt = d / dt (τθ) = τ dθ / dt P = τω Thus the power to turn a rigid body is given as P = τω |

In a `P-N` junction diode is `P` region is heavily doped than `n` region then the depletion layer isA. decreased with heavy dopingB. increased by reverse biasingC. decreased with light dopingD. increased by forward biasing |
|
Answer» Correct Answer - B In case of p - n junction diose, when it is reverse biased, the reverse voltage supports the barrir potential and hence the width of the depltion layer increases . In forward baising, the width decreases as the forward voltahe opposes the potential barrier. The width of the depletion region increases, if the diode is further dopend heavily as the movement of charge carrier decreases. Also, when the p -n junction is light doped, the width of depletion region increases, due to increases in the potential barrier. |

From the zygote, pluricellular organisms are formed by serial mitosis. Would this formation be possible if each cell made by mitosis had an identical life in relation to its antecedent cells? How did evolution solve that problem? |
|
Answer» The formation of complex and distinct pluricellular organisms would not be possible if mitosis in embryos produced only daughter cells with an identical life history as the mother cell, since there would not be differentiation and structural or functional specialization among cells. Evolution solved the problem creating the cellular differentiation process by which, motivated by stimulus not yet well-known by science, different and specialized cell lineages gave birth to different tissues, organs and systems that, as a whole, form the pluricellular organisms. Cellular differentiation probably is a very intricate process that activates and inactivates some genes within the cell in response to some stimulus. |

What is the typical biological function of the connective tissues? How is this function associated to the main features of its cells? |
|
Answer» The typical function of the connective tissues is to fill empty spaces among other body tissues. This function is related to the great capability of the cells of the connective tissue to secrete substances that constitute extracellular material, like collagen and elastic fibers, creating a significant spacing between these cells. (There are other important biological features of the connective tissues, such as substance transportation, defense of the organism, etc.) |

A smoothh disc is rotating with uniform angular speed `omega` about a fixed vertical axis passing through its centre and normal to its plane as shown. A small block of mass m is gently placed at the periphery of the disc. Then (pickup the correct alternative or alternatives) A. In comparision to `omega` the angular speed of the disc now increasesB. in comparision to `omega` the angular speed of the disc now decreasesC. in comparision to `omega` the angular speed of the disc now remains sameD. the block will move tangentially and fall of the disc. |
|
Answer» Correct Answer - B the only force block exerts on disc is parallel to axis of rotation of disc. This additional of disc. This additional force does not cause any torque on disc. Hence angular momentum of disc remains same. Since there is no friction between block and disc, the block remains in its position. |
