- A whale dives from the surface of the ocean at an angle of 30° below the horizontal and followed a linear path of 50 m long. How far below the water surface is the whale at this point? 50 m (50 m)/sin 30° (50 m) sin 30° (50 m) cos 30°arrow_forwardWhen a man stands near the edge of an empty drainage ditch of depth 2.80 m, he can barely see the boundary between the opposite wall and bottom of the ditch as in Figure (a) shown below. The distance from his eyes to the ground is h = 1.88 m. (Assume ? = 33.0°.) Figure a. A man of height h stands a horizontal distance d left of an empty rectangular drainage ditch of depth 2.80 m. A ray starts at the bottom right corner of the ditch, extends up and to the left to the upper left corner of the ditch, and then reaches the man's eyes. The ray forms an angle ? with the vertical. Figure b. A man of height h stands a horizontal distance xleft of a rectangular drainage ditch that is filled with water. A ray starts at the bottom right corner of the ditch and extends up and to the left to the upper left corner of the ditch at an angle ? with the vertical. Upon exiting the water, the ray bends to become less steep than the ray in water, and extends up and to the left to the man's eyes.

How far is Goku from the surface of the ocean as seen by Vegeta? 157.5 m 270 m 280 m 480 marrow_forward
- If the incoming ray hits the horizontal mirror farther to the right, is the angle the outgoing ray makes with the vertical greater than u, equal to u, or less than u?arrow_forwardThe fish in a pond is 15 m from the shore. Above what depth will he not be able to see a small rock at the water's edge? (nsu=1,33)arrow_forwardHow did you get the angle 110 degrees? When I input it into the calculator, the answer is -70.arrow_forward
- What is the optimal angle of projection for maximum displacement? When shoes that angle not work?arrow_forward. 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?arrow_forwardA submarine is 300 m horizontally from the shore of a fresh water lake and 100 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 210 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 diagram of the situation, identifying the two triangles that are important in finding the solution. (b) Find the angle of incidence of the beam striking the waterair interface. (c) Find the angle of refraction. (d) What angle docs the refracted beam make with the horizontal? (e) Find the height of the target above sea level.arrow_forward
- A high fountain of water is located at the center of a circular pool as shown in Figure P1.47. Not wishing to get his feet wet, a student walks around the pool and measures its circumference to be 15.0 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?
