Why is there a need to enhance non conventiona sources of energy?give two reasons |
|
Answer» 1.The growing consumption of energy has resulted in the country becoming increasingly dependent on Fossil fuels such as Coal, Oil and Gas.2. Rising prices of oil and gas and their potential shortage in the future has raised uncertainties about the security of energy supply in the future. It has serious repercussions on the growth of the national economy.To save expenses we should use non conventional sources of energy.3. Increasing Use of fossil fuels also causes serious environmental problems.Hence , there is a pressing need to use non conventional energy resources like the solar energy, wind, tide, Biomass and energy from waste material. (Any two reasons) There are various reason relating to need to harness the non-conventional sources of energy1) Conventional sources like fossils fuels take million of years to form so once used can\'t be replaced this is why these are also the non-renewable sources of energy. Thus non-conventional sources of energy are better choice .2) The increase use of fossils fuel led the carter the decrease of these resources and in future there could be the shortage of such resources to fulfill the increasing demand. Hence harness of non-conventional resources becomes necessary for future.\xa0Moreover fossils fuels causing the environmental damage and polluting the environment so the need for non-conventional sources like solar energy and wind energy is a better choice in this regard |

How is resistivity related to the use of the material? |
| Answer» A material with high resistivity means it has got high resistance and will resist the flow of electrons. A material with low resistivity means it has low resistance and thus the electrons flow smoothly through the material.For example, Copper and Aluminium have low resistivity. Good conductors have less resistivity. Insulators have a high resistivity. The resistivity of semiconductors lies between conductors and insulators. Gold is a good conductor of electricity and so it has low resistivity. | |

Distinguish between resistance and resistivity |
|
Answer» resistevity is not having 2terminals but resistance have terminals Resistance - which oppose the flow of current is known as resistance.Resistivity- the resistivity of a substance is numerically equal to the rod which is 1m in length and 1square metre area in cross section. Resistivity - resistivity is the measure of resistance of a material and in other words up to what extent will the material resist currents flow Resistance - unit R ,it is proportionally constant for the given metal at given temperature and is called resistance the graph between v and I is always a straight line with slope equal to R |

Why sky is blue ?? |
|
Answer» Sky has no colour but it seems to blue from earth because when sun light enters in our environment the refraction is done and most of blue light ray reflected so it seems to blue Kyun ki agar red ya green hota to accha nhi lgta thats why sky is blue. if u look any natural ponds you will find sky black with star during day time. blue colour is very refractive than other colours when it fall on atmosp. small subtance it spealt. Due to atmospheric refraction yrr |

What are the uses of lymphs? |
|
Answer» Lymph digest the fats present in our body A yellowish fluid that escape from the blood capillaries into the intercellular space lymph flows from this tissue to heart aasisting in transportation and destroying germs Components\tEditLymph returns proteins and excess interstitial fluid to the bloodstream. Lymph may pick up bacteria and bring them to lymph nodes, where they are destroyed. Metastatic cancer cells can also be transported via lymph. Lymph also transports fats from the digestive system (beginning in the lacteals) to the blood via chylomicrons.Circulation\tEditMain article: Lymphatic systemTubular vessels transport lymph back to the blood, ultimately replacing the volume lost during the formation of the interstitial fluid. These channels are the lymphatic channels, or simply lymphatics.[5]Unlike the cardiovascular system, the lymphatic system is not closed and has no central pump, or lymph heart (which are found in some animals). Lymph transport, therefore, is slow and sporadic. Despite low pressure, lymph movement occurs due to peristalsis (propulsion of the lymph due to alternate contraction and relaxation of smooth muscle tissue), valves, and compression during contraction of adjacent skeletal muscle and arterial pulsation.[6]Lymph that enters the lymph vessels from the interstitial spaces usually does not flow backwards along the vessels because of the presence of valves. If excessive hydrostatic pressure develops within the lymph vessels, though, some fluid can leak back into the interstitial spaces and contribute to formation of oedema.Flow of the lymph in the thoracic duct in an average resting person usually approximates 100ml per hour. Accompanied by another ~25ml per hour in other lymph vessels, total lymph flow in the body is about 4 to 5 liters per day. This can be elevated several fold while exercising. It is estimated that without lymphatic flow, the average resting person would die within 24 hours. [7] |
