- 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 workSatellite 1 has a mass m_1m1 and is located a distance r_1r1 away from the center of its host planet. Satellite 2 has half the mass as Satellite 1, but is located four-times the distance from the center of the host planet as Satellite 1. Determine the ratio of the magnitudes of the force of gravity between Satellite 1 and the planet to the force of gravity between Satellite 2 and the planet Ratio = Fplanet-on-1/ Fplanet-on-2Suppose the average mass of each of 20,000 asteroids in the solar system is 1017 kg. Compare the total mass of these asteroids to the mass of Earth. Assuming a spherical shape and a density of 3000 kg/m3, estimate the diameter of an asteroid having this average mass.
