Why two magnetic field lines don\'t intersect each other? |
|
Answer» Because magnetic force acting on north pole of a magnetic can be only in one direction but if magnetic fields intersects each other then magnetic force acting on north pole of magnet will be in two direction which is not possible Because if they intersect each other then magnet will detect two directions at the same time which is not possible Magnetic field lines do not intersect each other because if they did intersect each other then by placing a compass in that point of intersection would have pointed to different directions depending on the number of field lines intersecting at that point which is impossible.

What are the two main drawbacks of a chemical reaction? |
|
Answer» They aren\'t the drawbacks of a chemical reaction they are the incidents/characteristics of a chemical reaction...Drawbacks may be- irreversibility of the reaction and redox reaction that we know very well.....????? The chemical reactions suffer from a number of limitations and thus have a few drawbacks that are :-1) The physical states of the reactants and products.2) The concentration of the reactants and products.3) The conditions such as temperature, pressure or catalyst etc which affect the reaction.4) The heat changes accompanying the reaction i.e. whether heat is evolved or absorbed during the reaction.5) The formation of a precipitation or the evolution of gas in the reaction.6) The speed of the reaction.7) The nature of the reaction i.e. whether the chemical reaction is reversible or irreversible. It\'s may be harm us and may be highly exothermic |

What is the difference between evolution and speciation |
| Answer» Evolution is defined as evolution of different organisms from one common ancestor. For example, humans and apes evolved from a common ancestor. Organisms are different from each other due to various adaptations accumulated over time, humans evolved to become more intelligent than apes and developed complex languages for communication.Speciation on the other hand, is the diversion of a single organism\'s population into 2 or more genetically different groups. Speciation is caused mainly because of isolation of two groups of the organism\'s population, mostly geographic which leads to reproducive isolation, meaning the two groups stop breeding with each other. | |

Why can we put hydrogen in 1 or 17 group |
|
Answer» Belongs to helogen , hydrogen can be place in 1 and 17 grouo, it makes bond both in 1 and 7 group and complete its frequency Hydrogen can be kept in group 1 as it has one valence electon in its outermost shell .It can be kept in 17th group as it has also need of one electon as halogens.thank u guys. Did it helped u.? Hydrogen is special, in a sense that it behaves both as group I and group 17 (halogen) because it can accept as well as reject an electron to attain stable configuration. Because it is metal or non metal both |

human respiratory system |
| Answer» The human respiratory system is composed of a pair of lungs. These are attached to a system of tubes which open on the outside through the nostrils. Following are the main structures in the human respiratory system:Nostrils: There two nostrils which converge to form a nasal passage. The inner lining of the nostrils is lined by hairs and remains wet due to mucus secretion. The mucus and the hairs help in filtering the dust particles out from inhaled air. Further, air is warmed up when it enters the nasal passage.Pharynx: It is a tube like structure which continues after the nasal passage.Larynx: This part comes after the pharynx. This is also called the voice box.Trachea: This is composed of rings of cartilage. Cartilaginous rings prevent the collapse of trachea in the absence of air.Bronchi: A pair of bronchi comes out from the trachea; with one bronchus going to each lung.Bronchioles: A bronchus divides into branches and sub-branches; inside the lung.Alveoli: These are air-sacs at the end of bronchioles. Alveolus is composed of a very thin membrane and is the place where blood capillaries open. This is alveolus; where oxygen mixes with the blood and carbon dioxide exits from the blood. The exchange of gases; in alveoli; takes place due to pressure differential. | |
