Question

Define one pascal (Pa),the SI unit of pressure​

Answer 1

Answer:

A pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared. This unit is inconveniently small for many purposes, and the kilopascal (kPa) of 1,000 newtons per square metre is more commonly used.
