What is Green revolution in easy way |
| Answer» \tThe Green Revolution was a period when the productivity of global agriculture increased drastically as a result of new advances.\tDuring this time period, new chemical fertilizers and synthetic herbicides and pesticides were created.\tThe chemical fertilizers made it possible to supply crops with extra nutrients and, therefore, increase yield.\tThe newly developed synthetic herbicides and pesticides controlled weeds, deterred or kill insects, and prevented diseases, which also resulted in higher productivity.\tIn addition to the chemical advances utilized during this time period, high-yield crops were also developed and introduced.\tHigh-yield crops are crops that are specifically designed to produce more overall yield.\tA method known as multiple cropping was also implemented during the Green Revolution and lead to higher productivity.\tMultiple cropping is when a field is used to grow two or more crops throughout the year, so that the field constantly has something growing on it.\tThese new farming techniques and advances in agricultural technology were utilized by farmers all over the world, and when combined, intensified the results of the Green Revolution. | |

What do you mean by linear momentum |
| Answer» Linear momentum is the vector quantity and defined as the product of mass of an object, m, and its velocity, v. The letter ‘p’ is applied to express it and used as momentum for short.\xa0Please note that the body’s momentum is always in the same direction as its velocity vector. It’s a conserved quantity which means that the total momentum of a system is constant.\xa0The units of linear momentum are kg m/s.The linear momentum formula is given by,\xa0P = m vWhere,m = massv = velocity | |

What is Rutherford\'s theory |
| Answer» Rutherford model of an atom1)An atom consist of positively charged,dense and very small nucleus containing protons and neutrons.The entire mass of an atom is concentrated in the nucleus.2)The nucleus is surrounded by negatively charged electrons.the electrons are revolving around the nucleus in circular paths at very high speed.These circular paths of the electrons are called orbits.3)An atom is electrically neutral because the number of protons and electrons is equal.4)The size of nucleus is very small as compared to size of atom.\xa0Drawbac | |
