A fisherman and his young niece are in a boat on a small pond. Both are wearing life jackets. The niece is holding a large floating helium filled balloon by a string. Consider each action below independently and indicate whether the level of the water in the pond, Rises, Falls, is Unchanged or Can t tell.
True or False - The niece finds a cup and bails some water out of the bottom of the boat
True or False - The fisherman lowers the anchor and it hangs one foot above the bottom of the pond.
True or False -The fisherman lowers himself in the water and floats on his back.
True or False -The niece pops the balloon
True or False -The fisherman knocks the tackle box overboard and it sinks to the bottom.
True or False -The niece gets in the water and pops the floating helium balloon.

In scuba diving, a regulator is used so that the pressure of the air the diver breathes is close to that of the ambient water. A reckless swimmer decides to use a hose sticking out of the surface to breathe underwater while diving in a lake .When the air pressure in the lungs is at a pressure of around 0.150 atmospheres below the ambient pressure, lung injury may occur. Find the depth at which the swimmer would experience such a pressure differential.
