A deep-sea research vessel is operating in seawater of density 1.03×103 kg/m31.03 \times 10^3 \text{ kg/m}^31.03×103 kg/m3. The vessel descends to a new depth, which causes the external fluid pressure acting on its hull to increase by 0.25 MPa0.25 \text{ MPa}0.25 MPa.
Calculate the change in depth of the vessel, giving your answer to two significant figures. (Use g=9.81 m/s2g = 9.81 \text{ m/s}^2g=9.81 m/s2.)
