Be sure to show all calculations clearly and state your final answers in complete sentences.
43. Lost at Sea I. During a vacation, you decide to lake a solo boat trip. While contemplating the universe, you lose track of your location. Fortunately, you have some astronomical tables and instruments, as well as a UT clock. You thereby rut together the following description of your situation:
¦ It Is the March equinox.
¦The Sun is on your meridian at altitude 75° in the south.
¦ The UT clock reads 22:00.
a. What is your latitude? How do you know? b. What is your longitude? How do you know? c. Consult a map. Based on your position, where is the nearest land? Which way should you sail to reach it?

- I'm having trouble completing the problem I've attached a picture of below. I was able to find the the Earth's average speed in m/s relative to the sun by doing (2pi*(1.49x10^11))/31536000. But I am struggling to find the average velocity for the same thing over a period of one year in m/s. I was wondering how to calculate that? I've tried doing the (final velocity-initial velocity)/2 but the program doesn't accept my answer when using that approach.arrow_forwardI don't need the answer for the first part. I got it right.

The Sun, on the other hand, is approximately 700,000 km in radius and located, on average, one astronomical unit (1 au=1.5x108 km) from the Earth. Imagine that you stand near Mansueto Library, at the corner of 57th and Ellis.

- Which of the following statements about time are true? Pick all that apply. There is an "absolute" time that would be seen with the same value everywhere in the universe. and must be included in precision calculations of physics. You could describe the physics of Newton consistently at any time with the same ideas. We think that time passed the same way at the beginning of the universe as it does now, and that it enters the description of physics in the same way everywhere if we include the effects of gravity on time. According to Newton and Galileo, observers moving past one another at any constant velocity would see time pass in the same way.arrow_forward1.

Next, you walk in a constant direction for 8000 miles, and at your new location on the planet, you find that all stars rise straight up in the east and set straight down in the west, perpendicular to the horizon. How could you determine the circumference of the planet without any further observations? What is the circumference, in miles, of the planet? [OER Chapter 2, Figuring for Yourself #43]arrow_forward
