H 2.0m d A scuba diver training in a pool looks at his instructor as shown in the figure. The angle between the ray in the water and the perpendicular to the water is 0: 25 ° (a) What angle does the ray from the instructor's face make with the perpendicular to the water at the point where the ray enters? Angle, 0: о (b) Find the height, H, of the instructor's head above the water, noting that you will first have to calculate the angle of incidence. Note the scuba diver perceives the instructor as though the incident ray never refracted. Height, H: m (c) Find the apparent depth, x, of the diver's head below water as seen by the instructor. In the figure, d=2.00 m Note the instructor perceives the diver as though the incident ray never refracted. Apparent depth, x: m

During a visit to New York City, Lil decides to estimate the height of the Empire State Building (Fig. P1.57). She measures the angle of elevation of the spire atop the building as 20. After walking 9.0 102 ft closer to the iconic building, she finds the angle to be 25. Use Lils data to estimate the height h of the Empire State Building.

A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P4.22). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?
The barge of starch passes a light house. From the top of the light house 60 m high from sea level, the angle of depression (AOD) of the barge is 15 degree. A. Find the distance of the barge from the foot of the light house if the AOD is 15 deg. B. If the barge moves 120 m away from the lighthouse, what will be the resulting AOD from the top of the light house? C. If the barge moves 100 m closer to the lighthouse as it approaches to the original position, what is the resulting AOD?
A high fountain of water is located at the center of a circular pool. Not wishing to get his feet wet, a student walks around the pool and measures its circumference to be 32.0 m. Next, the student stands at the edge of the pool and uses a protractor to gauge the angle of elevation at the bottom of the fountain to be 55.0∘. How high is the fountain?
A high fountain of water is located at the center of a circular pool as shown in the figure below. Not wishing to get his feet wet, a student walks around the pool and measures its circumference to be 19.0 m. Next, the student stands at the edge of the pool and uses a protractor to gauge the angle of elevation at the bottom of the fountain to be 55.0°. How high is the fountain?
. A high fountain of water is located at the center of a square pool. Not wishing to get his feet wet, the student walks around the pool and measures its perimeter to be 20 m. Next, the student stands at the corner of the pool and uses a protractor to gauge the angle of elevation of the top of the fountain to be 55 degrees. In inches, how high is the fountain?
On a clear day a tiny fish hides under water (n water = 1.39 ) from an osprey under a circular leaf that has a diameter of 0.175 m. What is the maximum depth below the leaf that the fish can be so that it could not be spotted by the ospray? Provide your answer in meters with a precision of four places after the decimal.
