Answer 1

Answer:

2500pa or 2.5×10³pa

Explanation:

Force = 30N

Area = 120cm²

$= 120 \times \frac{1}{100} \times \frac{1}{100} {m}^{2}$

As 1 m = 100 cm

We know,

$p = \frac{force \: applied}{surface \: area}$

$= > p = \frac{30}{ \frac{120}{100 \times 100} }$

$= > p = \frac{30 \times 100 \times 100}{120}$

$= > p = \frac{100 \times 100}{4}$

$= > p = 25 \times 100$

$= > p = 2500pa$

Therefore your answer is 2500 pa or 2.5×10³ pa
