A catfish is 2.5 m below the surface of a smooth lake. (a) What is the diameter of the circle on the surface through which the fish can see the world outside the water? (b) If the fish descends, does the diameter of the circle increase, decrease, or remain the same? Assume that the index of refraction of water is 1.333.

The waves on the surface of a lake form a nearly spherical surface near peak of the wave, as shown in the image below. A bug is flying some distance above the surface of the water, as shown, and is being watched by a fish. The index of refraction of the water is ?=1.3 n = 1.3 . The fish is at a depth of 180cm, and the bug is flying a distance 32cm above the surface. The radius of...

Problem 2 A submarine is a distance L = 500 m below the surface of the ocean and sends a radio signal up to a battleship at the surface of the ocean Some of the signal is reflected at the surface back into the ocean. Some of the signal passes through the surface refracted. The signal that passes through the surface will make a cirele of diameter d. The battleship must be within that cirele to receive the...

(2) A pump is located H1-2 m above the water surface of a lake. The pump has an intake pipe diameter of D-20 cm and the head loss in the pipe that runs from the lake to the pump is hi 0.5 m. The outlet pipe diameter is d-30 cm. The pump has an efficiency of n 0.88 and uses P-15,000 ft.lb/s to pump water to a pond H2- 40 m above the lower lake surface. The head loss in...

Air 250 kPa Problem6 A tall tank has an orifice (circular opening) located 2.5 m below the water surface. The tank is closed with an ABSOLUTE pressure of 250 kPa. Atmospheric pressure is 100 kPa. (a) Neglecting frictional effects, determine the flowrate out of the tank. (b) As the tank empties, will the flowrate increase, decrease, or remain the same? Prove your answer with equations and words. Assume the air pressure in the tank remains constant. 2.5 m 10 cm

If you dive to 15 m below the surface of a lake, what is the pressure due to the water alone? Assume that the density of water is 1000 kg/m3; g = 9.8 m/s2; and PATM = 1.01 x 105 Pa.

A scuba diver is 45 m below the surface of a lake, where the
temperature is 5°C. He releases an air bubble with a volume of 10
cm3. The bubble rises to the surface, where the
temperature is 25°C. Assume that the air in the bubble is always in
thermal equilibrium with the surrounding water, and assume that
there is no exchange of molecules between the bubble and the
surrounding water. What is the volume of the bubble right before...
When the air temperature is below 0 C, the water at the surface of a lake...
When the air temperature is below 0 C, the water at the surface of a lake freezes to form an ice sheet. The longer the air remains at this temperature, the thicker the ice sheet will become. Will a lake in Minnesota that is uniformly 40 m deep ever freeze solid? To answer this, calculate how long it would take to freeze all the water in the lake. Assume that the upper surface of the ice sheet is steady at...

A scuba diver is 45 m below the surface of a lake, where the temperature is 5 degree C. He releases an air bubble with a volume of 18 cm^3. The bubble rises to the surface, where the temperature is 25 degree C. Assume that the air in the bubble is always in thermal equilibrium with the surrounding water, and assume that there is no exchange of molecules between the bubble and the surrounding water. What is the volume of...

water interface (the surface of the lake), it is partly
reflected back into the air and partly refracted
or transmitted into the water. This explains why on the surface of
a lake sometimes you see the reflection of the surrounding
landscape and other times the underwater vegetation.
These effects on light propagation occur because light travels at
different speeds depending on the medium. The index of refraction
