Which of the following best represents the excess pressure inside a soap bubble with a radius of 5.00 mm at a temperature of 20 °C, given that the surface tension of the soap solution is 2.50 × 10 ⁻² N m ⁻¹ ? If an air bubble of the same size is formed at a depth of 40.0 cm inside a container containing the soap solution (with a relative density of 1.20), what would be the pressure inside the air bubble, in units of
