Derive Newton's first law of motion from second law of motion |
|
Answer» Newton's second law states that net force is equal to change in momentum by TIME and by the first law of Newton a body D will retain its POSITION still an external force is applied to it for example if it is moving then it is moving and if it is in rest then it is in rest kill an external force applied on it so in second law of motion if we MAKE the net force zero and we know that mass is constant so there is no change in velocity so that the net force becomes zero that INSTEAD the velocity is constant that means that the object follows inertia |

write a note a natural farming and green farming bwrite a note on natural farming and green farming between them |
|
Answer» plz plz mark as brainlyExplanation:Natural farming is an ecological farming approach established by Masanobu Fukuoka (1913–2008), a Japanese farmer and philosopher, introduced in his 1975 book The One-Straw Revolution. Fukuoka described his way of farming as 自然農法 (shizen nōhō) in Japanese.[1] It is also referred to as "the Fukuoka Method", "the natural way of farming" or "do-nothing farming". The title refers not to lack of effort, but to the avoidance of manufactured inputs and equipment. Natural farming is related to fertility farming, organic farming, sustainable agriculture, agroecology, AGROFORESTRY, ecoagriculture and permaculture, but should be DISTINGUISHED from biodynamic agriculture.The system works along with the natural biodiversity of each farmed area, encouraging the complexity of living organisms—both plant and animal—that shape each particular ecosystem to thrive along with food plants.[2] Fukuoka saw farming both as a means of producing food and as an aesthetic or spiritual approach to life, the ultimate goal of which was, "the cultivation and perfection of human beings".[3][4] He suggested that farmers COULD benefit from closely observing local conditions.[5] Natural farming is a closed system, one that demands no human-supplied inputs and mimics nature.[6]Fukuoka's ideas radically challenged conventions that are core to modern agro-industries; instead of promoting importation of nutrients and chemicals, he suggested an approach that takes advantage of the local environment.[7] Although natural farming is considered a subset of organic farming, it differs greatly from conventional organic farming,[8] which Fukuoka considered to be another modern technique that disturbs nature.[9]Fukuoka claimed that his approach prevents water pollution, biodiversity loss and SOIL EROSION, while providing ample amounts of food.[10] |
