What is mile concept |
| Answer» 1 mole of a substance is equal to its atomic mass or molecular mass expressed in grams. The atomic mass expressed in grams is the gram atomic mass. The molecular mass expressed in grams is the gram molecular mass.For example, The atomic mass of sodium is 23 grams.Therefore, 23 grams of sodium is equal to one mole of sodium atoms.Similarly, the molecular mass of oxygen (O2) = 2 × Atomic mass of oxygen= 2 × 16 = 32 gAvogadro experimentally found that one mole of any substance always contained 6.022 × 1023 particles.This number is called the Avogadro’s number, denoted by N0. | |

Relstion between G and g? |
|
Answer» G-universal law of gravitation.g-acceleration due to gravity. Nueton\'s law of gravitation :- F =GMm/r2 - 1 From nueton\'s second law :- F =mg -2From 1 and 2 :GMm/r2 = mg GM/r2 = gTherefore,g=GM/r G stands for Newton\'s universal gravitational constant where as g stands for acceleratiom due to gravity at a certain point.G=6.7×10^-11 Nm^2/kg^2 where as G is constant. G is a scalar quantity whereas g is a vector quantity. |

Give reason why do we wear cotton clothes in summer |
| Answer» In summer we perspire more; cotton being a good absorber of water helps in absorbing the sweat and exposes it to the atmosphere for evaporation. When sweat evaporates from our body it takes heat from our body. Thus, our body loses heat and gets cooled. | |

What is newton\'s firest law |
|
Answer» Any object remains in the state of rest or in uniform motion along a straight line, until it is compelled to change the state by applying external force.Explanation:\xa0If any object is in the state of rest, then it will remain in rest untill a exernal force is applied to change its state. Similarly an object will remain in motion untill any exeternal force is applied over it to change its state. This means all objects resist to in changing their state. The state of any object can be changed by applying external forces only. If body is in rest or in motion it continued in motion or rest unless an external force applied. |

What is arithmetic tissue |
| Answer» Meristematic tissueis responsible for growth of plant. Meristematic tissue has the ability to divide and redivide to provide growth to plants.Generally, growth of plants occurs from specific region like root and shoot, nodes, girth of stem, leaf base etc. Therefore, meristematic tissue is present in these regions. Types of meristematic tissue are apical meristem, Intercalary meristem, lateral meristem.\tApical meristem\xa0is present on root and shoot tips of the plant. This tissue divides and results in growth of stem and roots of the plant.\tIntercalary meristem\xa0is present on leaf base and nodes.\tLateral meristem\xa0is responsible for increase in circumference i.e. girth of the stem or root of the plant.Meristematic tissue can divide and redivide upto an extent, after this they lose the ability to divide, thereby, converting into permanent tissue. Growth in plants with meristematic tissue can be easily demonstrated experimentally with help of onion bulbs. | |

| 8494. |
Longitudinal waves |
| Answer» \tSound waves are longitudinal waves as the particles of the medium through which the wave propagates vibrate in a direction parallel to the direction of propagation of waves.In longitudinal waves, the individual particles of the medium move in a direction parallel to the direction of propagation of the disturbance. The particles do not move from one place to another but they simply oscillate back and forth about their position of rest. This is exactly how a sound wave propagates, hence sound waves are longitudinal waves. | |

|
Answer» Zylem is correct Phloem xylem Food is transported by the phloem.Explanation:Phloem falls under the conducting tissue of the plants. The other type of conducting tissue is the xylem which is meant for transport of water and minerals. Phloem carries food in the form of a cell sap.This is carried from the leaves which, are the kitchen of plants to the other non-green parts of the plants. This can be demonstrated through the ring girdling experiment where the phloem is cut off. Phloem |
