Fill in the blanks :
It is the ___ light obtained by reflection from various uneven surfaces which enables us to see the objects around us.
Answers
❣️ TEMPERATURE ❣️
Temperature is a quantity which tells the thermal state of a body, i.e., the degree of hotness or coldness of the body. It also determines the direction of heat flow when two bodies at different temperatures after placed in contact.
❣️ WEIGHT & MASS ❣️
Weight is a vector quantity. Its direction is downwards towards the centre of earth. We can say, weight of a body is the force of gravity on it.
❣️ RELATIONSHIP ❣️
Weight actually loves mass very much and they are in a good relationship. Study of physics will let you know what is actually the relationship between weight and mass.
Weight = mass × acceleration due to gravity
In terms of symbols, W = mg.
Remember, the S.I. unit of weight is newton (N) and C.G.S. unit is dyne.
1 N = 10^5 dyne (Relationship)

It is the diffused light obtained by reflection from various uneven surfaces which enables us to see the objects around us.
❄️ Temperature is actually the thermal state of a body which also determines the direction of flow of heat energy from one body to another. In simple terms, temperature of a body is the degree of hotness or coldness of the body. It's S.I. unit is kelvin (K).
❄️ Weight = mass × acceleration due to gravity which can further be symbolised as W = m×g
❄️ DIFFUSED LIGHT
