A 1.4cm long object is placed perpendicular to the principal axis of a convex mirror of focal length 15cm at a distance of 10cm from it calculate the location of the image,height of the image ,nature of the image ??PLZ DO IT FAST |
|
Answer» Answer:given, convex mirror so focal length is positive so f=15cm by cartisan sign rule. object u=-10cm due to cartisan rule applying mirror formula 1/f = 1/V+1/u 1/15= 1/V - 1/10 1/15+1/10 = 1/V 1/6=1/V V=6cm by magnification formula m=-V/u = -hi/ho => V/u = hi/ho => 6/10 = hi/140. (1.4 m = 140cm) => hi = 84cm here hi is height of image. CHEERS DUDE Explanation: BRAINLIEST ANSWER PLEASE |

State the difference between prophase and anaphase stage of mitosis cell division with neat and labelled diagram. |
|
Answer» Mitosis is a type of cell division in which single haploid cell (N) or diploid cell (2n) divides into two haploid or diploid daughter cells that are same as the parent. Mitosis occurs in somatic cells of plants and animals. In this cell division, the two daughter cells have the same number of chromosomes as that in the parent cells. Mitosis consists of four basic phases: prophase, METAPHASE, anaphase, and telophase. 1.Prophase:- It is the first visible stage in karyokinesis. The chromosomes appear as long coiled threads called chromatids. The chromatin becomes shorter, thicker and visible due to the condensation of DNA. The chromatins are now called chromosomes. Stainability of nucleus increase. Each chromosome starts to splits longitudinally into two sister chromatids. These sister chromatids are attached to each other at the centromere. The nuclear membrane and nucleolus start to disappear and by the end, it will be completely disappeared. ii. Metaphase:- Nuclear membrane and nucleolus completely disappears and simultaneously appearance of spindle fibres. Spindle fibres are attached to the centromere of a chromosome. The chromosomes are arranged on the equatorial plane. The process of gathering of chromosomes in equator is called congression and plate formed is called metaphasic plate. iii. Anaphase:- The centromere of each chromosome splits into two sister chromatids and forms two daughter chromosomes. The daughter chromosomes are pulled towards the poles due to the contraction of spindle fibres and STRETCHING of interzonal fibres. During polar movement, the chromosomes show different shapes i.e. J, U, V, L or I shaped in appearance. At the end of anaphase, each pole will get one SET of daughter chromosomes. It is the SHORTEST phase and is also known as a migratory phase. iv. Telophase:- The daughter chromosomes reach respective poles and uncoil and become thin, long and visible. The spindle fibres start disappearing and finally disappear. The nuclear membrane and the nucleolus reappear. Two nuclei are formed at the end of telophase. Both the nuclei have the same number of chromosome as the parent cell. It is the last visible stage of karyokinesis and is also known as reorganization phase. It is followed by cytokines or division of cytoplasm. solution |

4. Explain why, when air is taken in and let out during breathing, the lungs always contain a residual vol |
Answer» We should know that during the breathing cycle, when air is taken in or inhaled and let out or exhaled, the lungs always CONTAIN a CERTAIN residual volume of air so that there is sufficient time 'for the oxygen to be absorbed' in to the blood and 'for carbon dioxide to be released' from the blood.Respiration is breathing or pulmonary ventilation by which atmospheric air is drawn in and carbon dioxide-rich alveolar air is released out. Diffusion of gases across the alveolar membrane is seen. Diffusion of oxygen and carbon dioxide takes place. Residual volume of air is the volume of air remaining in the lungs even after a forcible expiration.T his averages 1100ml to 1200ml. By adding up a few RESPIRATORY VOLUMES one can derive various pulmonary capacities, which can be USED in clinical diagnosis. |

All chemical changes involve ____ or_____ of energy. |
Answer» All CHEMICAL REACTIONS involve energy. ... These reactions, called exothermic reactions, release energy. In other chemical reactions, it takes more energy to break bonds in reactants than is released when bonds form in products. These reactions, called endothermic reactions, absorb energy.Chemical reactions often involve CHANGES in energy due to the BREAKING and formation of bonds.Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic. |

5. Define "POTENTIAL ENERGY OF AN OBJECT" and "LAW OF CONSERVATIONOF ENERGY". |
|
Answer» Answer: Explanation: "POTENTIAL ENERGY OF AN OBJECT" Potential Energy =PE=m*g*h. If object is already in MOTION it acquires ANOTHER kind of energy called Kinetic Energy. Formula for Kinetic Energy is: KE=1/2 mass * speed2. For example: throwing a ball requires work to be done on the ball. "LAW OF CONSERVATION OF ENERGY". The law of conservation of energy is a law of science that STATES that energy cannot be created or destroyed, but only changed from one form into another or TRANSFERRED from one object to another. |
