Answer:
p = h ρ g . p=(40.0m)(103kgm3)(9.80ms2)=3.92×105Nm2=392kPa. p = ( 40.0 m ) ( 10 3 kg m 3 ) ( 9.80 m s 2 ) = 3.92 × 10 5 N m 2 = 392 kPa . F=(3.92×105N/m2)(4.00×104m2)=1.57×1010N.
Examples A simple example of pressure may be seen by holding a knife to a piece of fruit. If you hold the flat part of the knife against the fruit, it won't cut the surface. The force is spread out of a large area (low pressure).
