A submarine is 306 m horizontally out from the shore and 110 m beneath the surface of the water. A laser beam is sent from the sub so that it strikes the surface of the water at a point 218 m from the shore. If the beam just strikes the top of a building standing directly at the water's edge, find the height of the building.
A submarine is 2.92 ✕ 102 m horizontally from shore and 1.00 ✕ 102 m beneath the surface of the water. A laser beam is sent from the submarine so that the beam strikes the surface of the water 2.14 ✕ 102 m from the shore. A building stands on the shore, and the laser beam hits a target at the top of the building. The goal is to find the height of the target above sea level. (The index...
A submarine is 282 m horizontally from the shore of a freshwater lake and 110 m beneath the surface of the water. A laser beam is sent from the submarine so that the beam strikes the surface of the water 209 m from the shore. A building stands on the shore, and the laser beam hits a target at the top of the building. The goal is to find the height of the target above sea level. (a) Draw a...
Chapter 26, Problem 018 A stone held just beneath the surface of a swimming pool is released and sinks to the bottom at a constant speed of 0.34 m/s. What is the apparent speed of the stone, as viewed from directly above by an observer who is in air? Take the refraction index of water to be 1.333.
Please draw detailed pictures 38. (II) A beam of light is emitted 8.0cm beneath the surface of a liquid and strikes the air surface 7.6 cm from the point directly above the source. If total internal reflection occurs, what can you say about the index of refraction of the liquid?
please explain step by step 17) In the figure, a laser positioned on a ship is used to communicate with a small two-man research submarine resting on the bottom of a lake. The laser is positioned 12 m above the surface of the water, an strikes and has an index of refraction of 1.33. How far horizontally is the submarine from the side of the ship? 12 m d it the water 20 m from the side of the ship....
A person is swimming 0.91 m beneath the surface of the water in a swimming pool. A child standing on the diving board drops a ball into the pool directly above the swimmer. The swimmer sees the ball dropped from a height of 5.4 m above the water. From what height was the ball actually dropped?
A person is swimming 0.87 m beneath the surface of the water in a swimming pool. A child standing on the diving board drops a ball into the pool directly above the swimmer. The swimmer sees the ball dropped from a height of 5.3 m above the water. Part A From what height was the ball actually dropped?
circle please 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...
A flashlight is held at the edge of a swimming pool at a height h = 2.4 m such that its beam makes an angle of θ = 41 degrees with respect to the water's surface. The pool is d = 2.25 m deep and the index of refraction for air and water are n1 = 1 and n2 = 1.33, respectively.what is the horizontal distance, D, from the edge of the pool to the point on the bottom of...
