Chapter 14 417 P14.15 The bell is uniformly compressed, so we can model it with any shape. We choose a sphere of diameter 3.00 m. The pressure on the ball is given by: PP g h w =+ atm ρ so the change in pressure on the ball from when it is on the surface of the ocean to when it is at the bottom of the ocean is Pg h w = . In addition: V VP B ghV B ghr B B V ww = =− × ρπ π 4 3 4 1 030 9 80 10 000 1 50 31 40 1 0 00102 3 3 10 , where is the Bulk Modulus. kg m m s m m Pa m 32 3 ej e j bg af .. . .

Therefore the diameter decreases by 0722 . m m . Section 14.3 Pressure Measurements P14.16 (a) We imagine the superhero to produce a perfect vacuum in the straw. Take point 1 at the
