Question 23
F=14.80 N correct to 2 decimal places F = 14.80 \text{ N correct to 2 decimal places} F=14.80 N correct to 2 decimal places P=4.00 Nm−2 correct to 3 significant figures P = 4.00 \text{ Nm}^{-2} \text{ correct to 3 significant figures} P=4.00 Nm−2 correct to 3 significant figures p=FA p = \frac{F}{A} p=AF​

ppp = pressure, FFF = force, AAA = area
