what is physical quantity .explain
Hello Aspirant,
See Physical quantity is nothing but just a property which is used to quantify the measurement. It is is denoted by the combination of a numerical value and unit. Let us take an example to understand it more clearly, suppose your mother asked you to bring sanitizer from the market and now how do you know that how much sanitizer you have to bring so your mother will tell you to bring 250mL of sanitizer or any other quantity. So here 250 mL is the physical which is quantifying the amount of sanitizer to be purchased from market.
I hope this information helps you.
Good Luck!!
