Fractional distillation |
| Answer» Fractional Distillation: Principle: This method is used for the separation of a mixture containing two miscible liquids, for which the difference in their boiling points is less than 25o C.Technique: The mixture is kept in a distillation flask attached with a fractionating column, having glass beads. The flask is then carefully heated. The mixture first evaporates and later condenses. The glass beads present in the fractional column provide a larger surface area for the vapours to cool down. This technique is used to separate mixtures made up of two miscible liquids with a difference in their boiling points less than 25oC. | |

Show that the energy of a free falling body is conserved |
| Answer» The falling of a body from a height towards the earth under its gravitational force is called free fall. So, whenever objects fall towards the earth under this force alone, we say that the objects are in free fall. While falling, there is no change in the direction of motion of the objects. But due to the earth’s attraction, there will be a change in the magnitude of the velocity. Any change in velocity involves acceleration. Whenever an object falls towards the earth, acceleration is involved. This acceleration is due to the earth’s gravitational force. Therefore, this acceleration is called the acceleration due to the gravitational force of the earth (or acceleration due to gravity). It is denoted by g. The unit of g is, m s–2.According to the second law of motion, force is the product of mass and acceleration. Suppose the mass of the stone be m. The acceleration involved in falling objects due to the gravitational force and is denoted by g. | |
| 6713. |
Action and reaction are equal in both magnitude and force then why theynot balance each other. |
| Answer» The third law of motion states that when one object exerts a force on another object, the second object instantaneously exerts a force back on the first. These two forces are always equal in magnitude but opposite in direction. The two opposing forces are also known as action and reaction forces. | |

What are scalar and vector? |
|
Answer» Scalar quantities are those quantities which require only the magnitude for their complete specifications. Physical quantities which can be completely specified by a\xa0number and unit, and therefore have the\xa0magnitude only, are scalars. Some physical quantities which are scalar are mass, length, time, energy, volume, density, temperature, electric charge, electric potential etc.Vector quantities are those quantities which require magnitude as well as direction for their complete specifications. Vectors are physical quantities, which besides\xa0having both magnitude and direction also obey the law of geometrical addition.\xa0(The law of geometrical addition, i.e. the law of triangular addition and law of parallelogram are discussed later in this chapter). Some physical quantities, which are vectors are displacement, velocity, acceleration, force, electric intensity, magnetic intensity, magnetic moment etc. the physical quantity having only magnitude is called scalar quantity .the physical quantity having both magnitude and direction is called vector quantity |

What is newton first law of motion |
|
Answer» ⚡Newton \'s first law of motion⚡:- An object in rest will remain in rest , an object in motion will remain in motion unless acted upon by an unbalanced force. The first law of motion is stated as: An object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force.All objects resist a change in their state of motion. The tendency of undisturbed objects whether they are at rest or moving with uniform velocity is called inertia. Hence, the first law of motion is also known as the law of inertia. |

Freely falling body is uniform or non uniform motion? |
| Answer» In a free falling body, acceleration due to gravity acts on the object.As a result, the body falls with increasing speed and before hitting the ground attains maximum velocity while initial velocity is zero.\xa0Here velocity is variable, so body covered unequal distances during equal intervals of time.Thus, free falling body is non uniform motion.\xa0 | |

Write about the newton\'s third law of motion |
| Answer» Explanation: Whenever a force is applied over a body, that body also applies same force of equal magnitude and in opposite direction.Example:\tWalking of a person - A person is able to walk because of the Newton’s Third Law of Motion. During walking, a person pushes the ground in backward direction and in the reaction the ground also pushes the person with equal magnitude of force but in opposite direction. This enables him to move in forward direction against the push.\tRecoil of gun - When bullet is fired from a gun, the bullet also pushes the gun in opposite direction, with equal magnitude of force. This results in gunman feeling a backward push from the butt of gun.\tPropulsion of a boat in forward direction – Sailor pushes water with oar in backward direction; resulting water pushing the oar in forward direction. Consequently, the boat is pushed in forward direction. Force applied by oar and water are of equal magnitude but in opposite directions. | |

Why are lysosome known as suicidal bags |
|
Answer» When the cells get damaged, lysosome may burst and the enzymes will digest it\'s own cell. Therefore, lysosome are known as suicide bags Lysosomes\xa0are cellular organelles that contain digestive enzymes that break down waste materials, foreign material and cellular debris. Lysosomes are capable of digesting nucleic acid, polysaccharides, fats, and proteins. Along with them lysosomes also digest or damage its own cells by its own enzymes, which lead to cell death. This process is called as autolysis. Hence lysosomes are also called as suicide bags |

What is element ?? |
|
Answer» Elements are the pure substance which cannot be broken into simpler substance Elements are the simplest substances in nature. There are around 90 naturally occurring elements on earth. They cannot be broken down into anything simpler by physical or chemical means. They consist of only one kind of atom and they can exist as either atoms (e.g., argon, calcium, aluminium) or molecules (oxygen, nitrogen). We can define elements as a species of atoms which have the same number of protons in their atomic nuclei. Although an element’s atoms have the same number of protons, they can have different numbers of neutrons and hence different masses. |

What is diploblastic |
|
Answer» Avadhesh parihar cant you post one thanks for gaurav seth he typed almost 5 paragraphs. \tDiploblasty is a condition of the blastula in which there are two primary germ layers: the ectoderm and endoderm.\tDiploblastic organisms are organisms which develop from such a blastula, and include cnidaria and ctenophora, formerly grouped together in the phylum Coelenterata, but later understanding of their differences resulted in them being placed in separate phyla.\tThe endoderm allows them to develop true tissue. This includes tissue associated with the gut and associated glands. The ectoderm on the other hand gives rise to the epidermis, the nervous tissue, and if present, nephridia.\tSimpler animals, such as sea sponges, have one germ layer and lack true tissue organisation.\tAll the more complex animals (from flat worms to humans) are triploblastic with three germ layers (a mesoderm as well as ectoderm and endoderm). The mesoderm allows them to develop true organs |
