I dont need the work shown I just need the answers in the

A fish maintains its depth in fresh water by adjusting the air content of porous bone or air sacs to make its average density the same as that of the water. Suppose that with its air sacs collapsed, a fish has a density of 1.18 g/cm3. To what fraction of its expanded body volume must the fish inflate the air sacs to reduce its density to that of water? d -1 points HRW10 14 P003.ssm. My Notes Ask Your Teacher Find the pressure increase in the fluld in a syringe when a nurse applies a force of 43 N to the syringe\'s circular piston, which has a radius of 1.2 cm.

As a result of the passage of a storm, the outside air pressure drops to 0.95 atm, but inside the pressure is held at 1.0 atm. What net force pushes out on the windo w?

Solution

(V_e - V_o) / V_e = 1 - V_o/V_e

1 - [1.0 / 1.18] = 0.1525 = 15.25 %

---------------------------------------------------

delta P = F / pi r² = 43 / pi * 0.012²

= 9.5 * 10⁴ Pa

-------------------------------------------------

F = (1 - 0.95) * (1.013 * 10⁵) (3.4 * 2.3)

= 3.84 * 10⁴ N
