1.8. Having access to the vast informational resources of the Library of Alexandria,
Eratosthenes knew that the distance between Syene and Alexandria is 5000 stadia. One
stadion (plural stadia) was a unit of length commonly used at the time; it was
approximately equal to 160 meters.
Express the distance between Syene and
Alexandria in meters: s =
1.9. Travelling from Syene to Alexandria, one travels along the arc of a circle. Recall that for
a circle of radius R, the length s of an arc and the angle 0 subtended by that arc are
related by the following equation:
[8]
In using this equation, the angle must be measured in radians. Use equation [8] to
S =
RO
calculate the radius of Earth: R =
This is a mathematical problem by converting the distance from the sun to earth then using what ever is given!

- The radius of the earth is 6400 Km and the height of a person is 1.7m, how high can you stand to see how far the horizon is from you (going back in degrees after the arc)arrow_forward(a) Jupiter's third-largest natural satellite, Io, follows an orbit with a semimajor axis of 422,000 km (4.22 ✕ 105 km) and a period of 1.77 Earth days (PIo = 1.77 d). To use Kepler's Third Law, we first must convert Io's orbital semimajor axis to astronomical units. One AU equals 150 million km (1 AU = 1.50 ✕ 108 km). Convert Io's a value to AU and record the result. aIo = AU (b) One Earth year is about 365 days. Convert Io's orbital period to Earth years and record the result. PIo = yr (c) Use the Kepler's Third Law Calculator to calculate Jupiter's mass in solar units. Record the result. MJup(Io) = MSun (d) Based on this result, Jupiter's mass is about that of the Sun. Jupiter has a similar fraction of the Sun's volume. The two objects therefore have rather similar density! In fact, Jupiter has a fairly similar composition as well: most of its mass is in the form of hydrogen and helium.arrow_forwardTo find the acceleration from equation (a=v^2/r), the velocity of an object traveling in a circle is the distance traveled (i.e. the circumference, which is 2?r) divided by the travel time (i.e. the period T). The Moon’s sidereal period is 27.32 days. Convert this period into seconds. Complete Table 1 for the Moon to find its orbital period in seconds, its average velocity in meters per second and its acceleration in meters per second^2 where Orbital radius (m) = 3.84 x 10^8.arrow_forward
- To complete this exercise, you need to know that the circumference of a circle is proportional to its radius, and that the constant of proportionality is 2π. You do not need to know either the radius of the Moon’s orbit or the radius of Earth. For purposes of this exercise, we assume that the Moon’s orbit around Earth is circular. In one trip around Earth, the Moon travels approximately 2.4 million kilometers. Another satellite orbits Earth (in a circular orbit) at a distance from Earth that is 1/4 that of the Moon. How far does this satellite travel in one trip around Earth? (Use decimal notation. Give your answer to one decimal place.) A rope is tied around the equator of Earth. A second rope circles Earth and is suspended 77 feet above the equator. How much longer is the second rope than the first?arrow_forwardA car is driving on a circular track with a radius of 1 (km). In the point in south (sin((3π)/2)) on the field is a radar meter. At a given time, the car is 1/2 km from the radar meter (in air measurement)and the distance between the car and the meter increases by 50 km / h. How fast driving the car north? (hint: the car will also have an east / west movement, but here it is only asked about the north / south movement)arrow_forwardI measured the angular separation of Jupiter's moons in arcminutes/arcseconds and converted this angle to radians. The conversion factor for degrees to radians was 57.3 degrees per radian. Which unit of measurement is larger? 1 degree or 1 radian?arrow_forward
