The pascal (Pa) is the unit of pressure or stress in the International System of Units (SI). It is named after the scientist and mathematician Blaise Pascal. One pascal is equivalent to 1 newton (N) of force applied over an area of 1 square meter (m2). The pascal is also used to ...
Pascal is the unit of pressure. Pressure =Force/Area. 1 Pa=1 N/m2=(1 kg m s-2)/m2=kg m-1 s-2. 4. 1 Pascal is defined as the pressure exerted on an area 1 m2 by a force of 1 N. Hence, option (D) is correct. Suggest Corrections 1 Similar questions Q. What is 1 pasc...
