- You have read all the material you could find about The Howler and about The Cylinder of Fate . Based on this reading and some information about the sea floor and tides in the area where The Howler was thought to have sunk, you suggest that the team start by taking the search boat 65 meters due east of shore. At this distance the angle of depression between the shore and the hypothetical location of The Howler and its treasure should be about. The search boat will be at the vertex of a angle between the shore and the treasure below. Use this information and what you know about solving triangles using trigonometric functions to explore the questions below. What is the straight-line distance between the treasure and the shore? You can round to the nearest hundredth, as needed. Show your workarrow_forwardFrom the data measured read off the period, P and the orbital radius, a from thegraph for the moon Ganymede . These values will have units of hours for the period P, and Jupiter Diameters (J.D.) for a. Enter your results here:P (period) = _________ hours a (orbital radius) = ________ J.D. After,In order to use Kepler's Third Law, you need to convert the period into years, using: 1 day = 24 hours and 1 year = 365.25 days. The orbital radius must be converted to A.U., using 1050 J.D. = 1 A.U. Enter your converted values here: P (period) = _________ years a (orbital radius) = ________ A.U.arrow_forwardQ-1 Define a garden city and enumerate various features of a garden city?
