Question

SI unit of pressure is 1pascle(1pa) where : (a) 1pa = 1Nm-2 (b) 1pa=1Nm-1 (c) 1pa=1Nm (d) 1pa = 1Nm2​

Answer 1

Answer:

Nm-2is the answer for your answer

Answer 2

Answer:

(a)1pa=1Nm-2

Explanation:

pascal=force/area acting on it

          =Newton/metre per sq. (substituting the values)

therefore, newton per metre sq.(Nm-2)
