1.	How can we classify variables and constants based on dimension. Give example for each type?
Answer» Solution :Dimensional variables : Physical quantities, that possessdimensions and have variable values are called dimensional variables. EG: Length, velocity, and acceleration etc. Dimensionless variables : Physical quantities that have no dimensions, but have variable values are called dimensionless variables. Eg: Specific GRAVITY, strain, refractive index etc. Dimensional CONSTANT : Physical quantities that posses dimensions and have constant values are called dimensional constants. Eg : Gravitational constant, Planck'sconstant etc. Dimensionless Constant : Quantitie which have constant values and also have no dimensions are called dimensionless constants.
