    Answer:

    Explanation:

    Given that, .

    Pressure around scuba is

    P = 10^5 Pa

    1 Pa = 1 N/m²

    Then

    P = 10^5 N/m²

    Descending height

    h = 10m

    Change in force per unit square centimetre

    We know that,

    Pressure = Force / Area

    Then,

    Force / Area is the required question we are finding

    Then,

    Force / Area = 10^5 N / m²

    So, let convert the m² to cm²

    100cm = 1m

    (100cm)² = (1m)²

    10⁴cm² = 1m²

    Then,

    Force / Area = 10^5 N/m² × 1m² / 10⁴cm²

    Force / Area = 10 N/cm²

    So, the force per unit square centimeters is 10.
