Chapter S1, Problem 43EAP
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?

You are an astronomer on planet Tirth, which orbits a distant star. It has recently been accepted that Tirth is spherical in shape, though no one knows its size. One day, you learn that on the equinox your sun is directly overhead in the city of Tyene, located 450 kilometers due north of you. On the equinox, you go outside in Alectown and observe that the altitude of your sun is 85 ∘∘.
What is the circumference of Tirth?
Express your answer in kilometers to two significant figures.

- Number 1 how do we figure outarrow_forward1List and describe Newton’s Laws of motion. 2 Describe what the sky would look like at the North Pole at night. How would the sky change over a 24 hr period?arrow_forwardFor this short response assignment, your job is to demonstrate your understanding of SI units and how they can be applied on an astronomical scale. To do this, answer each of the following with a brief explanation of the mathematics used to get there.The speed of light is 3*10^8 m/s (aka 300,000,000 meters per second). What is the speed of light in centimeters per second, kilometers per second, and miles per hour? (Hint: there are roughly 1.6 km per mile and 3600 seconds per hour) Remember to show the math; If light from the closest star to our solar system takes about 4.2 years to get to us, how far away is that star in units of Gm (aka Gigameters)? Again, explain your work.arrow_forward
- Watching a Helicopter Take Off At a distance of 44 ft from the pad, a man observes a helicopter taking off from a heliport. If the helicopter lifts off vertically and is rising at a speed of 37 ft/sec when it is at an altitude of 124 ft, how fast is the distance between the helicopter and the man changing at that instant? (Round your answer to one decimal place.) ft/secarrow_forwardWhy do we say that light travels in straight lines?

- What is the number of miles in a light-year, using (see picture) mi/s as the speed of light? I know the number of seconds in a year and 365 days will help but confused on how to put it in the equation.arrow_forwardHow do we define the time interval of one "second" now, and keep track of elapsed time accurately enough to navigate spacecraft through the solar system, or place you on Earth with a GPS receiver? From the daily rotation of Earth with respect to distant stars. Counting cycles of oscillation in a cesium atom, the so-called "atomic" clock. From the daily rotation of the Earth on its axis. From the annual revolution of Earth about the Sun starting at noon on one year and ending at noon on the following year.arrow_forwardThe Earth is travelling around the sun at a speed of about 67,000 miles per hour [mph]. If it takes one year [yr] for the Earth to circle the Sun and we assume the Earth?s orbit is circular, what is the radius of the orbit in units of meters [m]? Use an appropriate SI prefix to report your answer so there are one, two, or three digits to the left of the decimal point.arrow_forward
