Why the colour of sky bags s blue |
| Answer» The molecules of air and other fine particles in the atmosphere have a size smaller than the wavelength of visible light. Thus, they are more effective in scattering light of shorter wavelengths at the blue end than light of longer wavelengths at the red end. Red light has a wavelength greater than blue light. Thus, when sunlight passes through the atmosphere, the fine particles in air scatter blue colour (shorter wavelengths) more strongly than red. The scattered blue light enters our eyes. | |

Air is what mixture or compound if any from both then why |
| Answer» In general compounds are formed by the chemical combination (chemical reaction) of different elements, molecules with each other. Whereas mixtures are formed by the combination of different elements, molecules and even compounds which are not chemically reacted with each other.Air is considered as a mixture of gases, as the component gases does not reacts with each other.If the gases present in it reacts with each other then it will not considered as mixture but as a compound. | |
| 9875. |
Why air is called a mixture not a gas? |
|
Answer» Because air is no only one type of gas.this is mixture of more than one gas .so this is mixture .. In atmosphere there are many gases like carbon dioxide,oxygen,nitrogen,etc.so,they are called mixture.And gas means there will be only one type of substance. |

Why lysosome know as sucide bags |
|
Answer» Lysosomes are 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. when the cell get damage lysosomes may burst or digest their own enzymes.therefore it is called suicide bag |

Define the universal law of gravitation?????????? |
| Answer» Universal Law of gravitation was formulated by Sit Issac Newton.It states thatEvery body in universe attracts every other body with a force which is directly proportional to the product of their masses and inversely proportional to the square of distance between them.

| 9897. |
What is the second law of motion ? |
| Answer» Newton\'s second law of motion gives the relationship between the force and acceleration.The second law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force.The rate of change of momentum of an object is proportional to the applied force. So, Newton\'s second law of motion can be expressed as definition of forceForce ∝ change in momentum / total time | |
