Will you help me with this units question?
Simplify the units: (Pa N m^4) / J
C. kg m/s
I keep getting J as my answer but the correct answer is N.

Pa = N/m²
J = Nxm
Pa x N x m^4 / J = (N/m²) x (N) x m^4 / J = N² x m² / J = J² / J = J
double check that question and answer!

newton (N) force kg·(m/s2) kg·m·s-2
pascal (Pa) pressure N/m2 kg·m-1·s-2
joule (J) energy or work N·m kg·m2·s-2
watt (W) power J/s kg·m2·s-3
Put them in the equation and cancel out any similar terms eg N/m cancels out N/m etc it would end up with N.
