Answer:
Solution below.
Explanation:
This Question involves the pressure formula.
Pressure = Force ÷ Area
where unit of area is
[tex] {m}^{2} [/tex]
i) We can directly use the formula to solve for A, the area.
P = F ÷ A
20000 = 200 ÷ A
20000 × A = 200
A = 200 ÷ 20000
A =
[tex]0.01 {m}^{2} [/tex]
ii) For this part, we can use the answer found in part (i) to convert to the required units.
We know that:
[tex]1 {m}^{2} = (100cm) \times (100cm) \\ 1 {m}^{2} = 10000 {cm}^{2} \\ 0.01 {m}^{2} = 10000 \times 0.01 \\ = 100 {cm}^{2} [/tex]
