Why are magnetic keepers used to store magnetsdefine cartilage |
|
Answer» Answer: Magnetic keepers are soft iron bars placed at either end of the pair of magnets. It is USED to avoid self-demagnetisation of magnets. Cartilage a strong and smooth substance made up of “CHONDROCYTES,” or specialized cartilage cells, that produce a matrix of collagen, PROTEOGLYCANS (a special type of protein) and other non-collagenous proteins. These materials help cartilage ATTRACT water and give it its shape and specific PROPERTIES. |

Speech on covid 19positive and negative side |

Answer» COVID-19 has changed our lives forever. While the COVID-19 pandemic is still unfolding, many reforms have already started digging their heels in, both in terms of collateral damage and the co-benefits of fighting the virus. With deaths and suffering being the immediate ugly face of the disaster, here are the impacts of the pandemic that will transform our lives in the long run: The environment is cleaner since the lockdowns kicked in, and may never get as bad as before –Nearly everyone witnessed the bluer sky, cleaner air, clearer moon and stars, and LOUDER bird songs, and we saw images of cleaner rivers and lost mountain vistas. Though fears of returning pollution will certainly come true once the constraints ease, some benefits will remain on. A significant number of city travelers on the brink, reluctant to move from home to work, online meetings, and online learning, took the plunge and no turning back. Time and expense advantages, both travel and infrastructure, would be more economically significant now that they have been tested and the initial mental barrier of these cultures has been crossed through organizations. The complexity of disasters will be better understood, triggering higher preparedness levels –While the scientific community has long spoken about complex disasters, pandemics, climate-induced disasters, and mega-disasters, the gravity of these definitions has failed to disrupt both political will and public actions. Maybe COVID-19 made every PERSON on earth sit down and see how fragile our lives and lifestyles are on the one hand, and how volatile and strong natural hazards are on the others. ECONOMIC rebalancing and its ill effects –A tiny virus has kneeled the world’s leading economies. It is expecting a major recession. Different countries are likely to recover at various places, some potential race winners, and some losers. Fragile societies and economies will take longer to recover from the impacts of the pandemic, and will lose on many fronts. For many, DEBT will RISE past manageable rates, and assistance will be hard to come by in a whole world reeling from the pandemic’s secondary effects, lockdowns, and diminishing demand for goods and services. The support that may come can be dangerous and may cause the colonialism of a new age. Refer to the attachment after this. |

What are industries?What are cottage industries?Differentiate between agro-based and mineral-based industries?What are the factors that help to decide the location of an industryDifferentiate between large-scale and small scale industries.Why are industries important to a nationdon,t search on G.oogle |
Answer» ❤︎ Answer :-1. Branch of economic or commercial activity concerned with the processing of raw materials and manufacture of goods in factories are called Industries.2. A cottage industry is a small-scale, decentralized manufacturing business often operated out of a home rather than a purpose-built facility. They often focus on the PRODUCTION of labor-intensive goods but face a significant disadvantage when competing with factory-based manufacturers that mass-produce goods.* Agro based industries :- Industries that have agricultural produce as raw materials are known as agro based industries.* Mineral based industries :- These industries USE minerals, both metallic and non metallic, as raw materials are based on ferrous and non ferrous metallurgical processes.3. The factors that help to decide the location of an industries are :-Raw materials.Water Supply.Energy.Transport.Labour. e.t.c.* Large scale industries :- These industries require large infrastructure and large NUMBER of workers. These industries play a large role in INDUSTRIALIZATION.* Small scale industries :- These industries are small industries managed mostly by private individuals.4. Rapid industrialization provides support and strength to our agricultural base. Industries produce goods equipment required for the defense of the country.》 Note :- Not Copied FORM Internet. |

State three ways by which you can maximise the loss of energy in calorimeter |
|
Answer» Answer: This assumes no heat is lost to the SURROUNDINGS from the calorimeter. Heat lost by hot water = heat GAINED by cold water + heat gained by calorimeter. The minus sign indicates that the hot water is LOSING heat, whereas the cold water and the calorimeter are GAINING heat. |

Make a 50 cm × 50 cm bed of dry sand about 10 cm in thickness. Make surethat its top surface is levelled. Take a wooden or a plastic stool. Cut two strips of graph paper each with a width of 1 cm. Paste them vertically on any leg of the stool—one at the bottom and the other from the top. Now gently put the stool on the sand bed with its legs resting on the sand. Increase the size of sand bed if required. Now put a load, say a school bag full of books, on the seat of the stool. Mark the level of sand on the graph strip. This would give you the depth, if any, to which the legs of stool sink in sand. Next, turn the stool upside down so that now it rests on its seat on the sand bed. Note the depth to which the stool sinks now. Next, put the same load on the stool and note the depth to which it sinks in the sand. Compare the pressure exerted by the stool in the two situations. |

Why speed is said to be accelarated motion? |
|
Answer» Uniform circular motion is accelerated because the velocity CHANGES due to continuous change in the DIRECTION of motion. So, even when the body moves ta a constant speed, its velocity is not constant. Thus, for a body moving in a circular path at a constant speed, its velocity changes continuously.
