Textbook Question
Chapter S1, Problem 53EAP
Celestial Navigation. Briefly discuss how you think the benefits and problems of celestial navigation might have affected ancient sailors. For example, how did they benefit from using the north celestial pole to tell directions, and what problems did they experience because of the difficulty in determining longitude? Can you explain why ancient sailors generally hugged coastlines as much as possible on their voyages? What dangers did this type of sailing pose? Why did the Polynesians become the best navigators of their time?

- Question 4 Every year over 105 km2 of forest area is lost to human activity. This is about one seventh the area of Texas as shown on the map in red. If our planet has 19.4 x 106 km2 of forest area, how long will it to take to lose it all? Hint: divide the total forest area by the given rate of deforestation. Calculations: Answer: Question 5 The Great Pacific Garbage Patch is an area of plastic waste twice the size of Texas in the Pacific Ocean. It is estimated there are 1.8 x 1012 pieces of plastic in this patch. If the world’s population is 8 x 109, how many pieces of plastic are there per person? Hint: divide the total pieces of plastic by the number of people. Calculations: Answer:arrow_forwardImpact Energy. Consider a comet about 2 kilometers across with a mass of 4 × 1012 kg. Assume that it crashes into Earth at a speed of 30,000 meters per second (about 67,000 miles per hour). a. What is the total energy of the impact, in joules? (Hint: The kinetic energy formula tells us that the impact energy in joules will be 1 × m × v2, where 2 m is the comet’s mass in kilograms and v is its speed in meters per second.) b. A 1-megaton nuclear explosion releases about 4 × 1015 joules of energy. How many such nuclear bombs would it take to release as much energy as the comet impact? c.

Use the relationship between distance (d), time (t) and speed (v), d = vt to repeat the calculation we did in class, but this time using the English units. Use the fact that GEO satellites orbit at 22,236 miles above Earth's equator, and that the speed of light is 1.86 x 105 mi/s. (Note that both of these values are equivalent to those used in class.)

- We need to create a scale model of the solar system (by shrinking the sun down to the size of a basketball or ~30cm). First, we will need to scale down actual solar system dimensions (planet diameters and average orbital radiuses) by converting our units. There are two blank spaces in the table below. We will effectively fill in the missing data in the next set of questions. Use the example below to help you. Example: What is the scaled diameter of Mercury if the Sun is scaled to the size of a basketball (30 cm)? The actual diameter of Mercury is 4879 km The Sun's diameter is 1392000 km If the Sun is to be reduced to the size of a basketball, then the conversion we need for this equation will be: 30cm1392000km Here is how we run the conversion: 4879km×30cm1392000km=0.105cm or 0.11cm if we were to round our answer. This means that if the sun in our model is the size of a basketball, Mercury is the size of a grain of sand. We can also see by looking at the table, that we would…arrow_forwardhow do you compare us with people from the moon. Explain?arrow_forwardHow do we know?
