A spherical soap bubble has an inside radius R, a film thickness t, and a surface tension
σ. Derive a formula for the pressure within the bubble relative to the outside atmospheric
pressure. What is the pressure difference for a bubble with a 4 mm radius? Assume σ is the
same as for pure water.

- A U-tube of 2.5 mm inside diameter and 900 mm length has one end closed. The other end is connected to a funnel of height 50 mm. Mercury is poured into the funnel to trap air in the tube. If trapped air is compressed isothermally, what is height to which mercury will go inside U-tube and then starts to spill over the funnel?

The gate is hinged at C, and consists of a vertical section AB of length H and an inclined section BC also of length H inclined at an angle with respect to the horizontal. Obtain an expression for the force P required to hold the gate in position. Neglect the weight of the gate and friction in the hinge.
