Question

sabse choti unit kay hoti hi​

Answer 1

Answer:

Zepto Second

Step-by-step explanation:

A millimeter is the smallest unit. There are 10 mm in one centimeter, if an object is smaller than one centimeter, you would use millimeters

Or

zeptosecond

What is a zeptosecond? A zeptosecond is a trillionth of a billionth of a second. That's a decimal point followed by 20 zeroes and a 1, and it looks like this: 0.000 000 000 000 000 000 001. The only unit of time shorter than a zeptosecond is a yoctosecond, and Planck time.

Hope it help
