Give the functions of each sense organ? |
| Answer» Eyes: A good sense of sight is achieved by healthy eyes. Eyes are the organs of the visual system. Eyes provide vision and the sense of sight to human beings, animals, birds, fishes, etc. Human beings can have various eye colors depending on the amount of melanin present in one’s body. The eye color can vary from brown to blue. However, eyes are sensitive to light.Nose: The organ for the sense of smell is the nose.\xa0Ears: The organ for the sense of hearing is ears.Skin: The organ for the sense of touch is skin. Skin is the largest organ as it is located throughout the human body.Tongue: The organ for the sense of taste is the tongue. The tongue has various receptors which can detect whether the item consumed is salty, sweet, bitter or sour.\xa0 | |

Give examples of redox reaction |
| Answer» A redox reaction is a type of electrochemical reaction where oxidation and reduction occur simultaneously. Redox is the short form for “reduction and oxidation”.Example of redox reaction:i. When methane reacts with Oxygen to give Carbon dioxide and water. During this reaction Carbon is oxidised due to removal of Hydrogen and simultaneously Oxygen is reduced due to addition of Hydrogen.ii. In the reaction Copper oxide with Copper sulphate gives copper and Sulphur dioxide.During this reaction oxygen an electronegative element is removed from Copper oxide and Copper an electropositive element is removed from Copper sulphate. | |

| 62360. |
What is meant by optical density? |
| Answer» Optical Density: Medium having greater value of refractive index is called optically denser medium, this means light will travel at slower speed in optically denser medium compared to in an optically rarer medium. The optical density of a medium is not the same as its physical density. The physical density of a material refers to the mass/volume ratio. The optical density of a material relates to the sluggish tendency of the atoms of a material to maintain the absorbed energy of an electromagnetic wave in the form of vibrating electrons before reemitting it as a new electromagnetic disturbance. | |
| 62361. |
What is mass density? |
| Answer» Mass density is mass per unit volume. It is possible that mass density of an optically denser medium may be less than that of an optically rarer medium (optical density is the ratio of the speed of light in two media). For example, turpentine and water. Mass density of turpentine is less than that of water but its optical density is higher. | |

Defination of reflection and refraction |
| Answer» Reflection: The bouncing back of rays of light from a polished and shiny surface is called reflection or reflection of light. It is similar to bouncing back of a football after colliding with a wall or any hard surface.Refraction of light: When travelling obliquely from one medium to another, the direction of propagation of light in the second medium changes. This phenomenon is known as refraction of light. | |

Explain the electric potential difference |
|
Answer» Electric potential define as work done in moving positive charge from infinitive to that points,then potential difference define as the difference of electric potential between two points called potential difference. Ohm\'s law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points. Potential difference is the work done in moving a unit of positive electric charge from one point to another. |
