Using a compass determine the direction of south. Using a clock find out the time when the sun is south. For every hour after mid-day you are 15 degrees west of the point where the sun is south at mid-day. The clock should be set to mid-day when the sun is at longitude zero to get absolute values rather than relative values.

What is the longitude and and latitude of the tropic of cancer?
The two tropics are lines of latitude at 23°26′13.0″ North and South of the Equator and they intersect all lines of longitude.
What invention allowed sailors do plot their positions at sea by looking at the stars?
The SEXTANT. This instrument will give the latitude of a ship. However, because of solar movements a CLOCK(Time piece) is needed to determine the longitude(meridian). So the two inventions are ; - The Sextant, and the Clock .
What are the two things that are necessary for clouds to form?
air and water
How can you tell which planet has the most circular orbit?
You can look through a list of the planets' orbits to see which one has the smallest eccentricity, and the answer is Venus, 0.006787. But if you are an astronomer wanting to find it out by observing the planets in the sky, you need to have five accurate positions for each planet, spaced out across a good fraction of the orbit, and then you can calculate the 'elements' of the orbit. One of the elements is the eccentricity. The eccentricity and the semimajor axis determine the shape and size of the orbit. Then there is the longitude of perihelion, which sets the orientation of the major axis of the ellipse. Two more are the inclination of the plane of the orbit to the plane of the Earth's orbit, and then the longitude of the ascending node, which defines the line of intersection of the two planes. Finally the longitude at the Epoch and the date of the Epoch are required because they set the starting conditions for the model.
A person knows the sun time on the prime meridian and the local sun time What determination can be made?
By knowing the sun time on the prime meridian and the local sun time, one can determine their east-west position on the Earth's surface. The time difference between the two locations can be used to calculate the longitudinal difference, helping to pinpoint the exact location.
Which major city is located at 56 n Latitude and 38 e Longitude?
Moscow is the major city located at 56 N latitude and 38 E longitude.
What two quantity are necessary to determine a vector quantity?
Magnitude and direction
Explain how you can determine if your location is east or west longitude?
You can determine if your location is east or west longitude by looking at the numerical value of your longitude coordinates. If the value is positive (+) then you are in the eastern hemisphere, indicating east longitude. If the value is negative (-) then you are in the western hemisphere, indicating west longitude.
Why is it necessary to take both the vernier readings of theodolite?
Taking both the upper and lower vernier readings of the theodolite helps to eliminate any errors caused by misalignment or wear in the instrument, resulting in a more accurate measurement. Comparing the two readings can also help detect any potential issues with the theodolite's precision.
Are there three readings on Sundays and holidays mass?
There are two readings and the gospel, for total of 3
How do you predict about the reading on the two ammeters?
To predict the readings on two ammeters in a circuit, you need to analyze the circuit configuration and the current paths. Each ammeter will measure the current flowing through the branch it is connected to. By applying Kirchhoff's current law and Ohm's law, you can calculate the currents through each branch and determine the readings on the ammeters.
What is the effect of variation of power factor on readings of two wave meters used in 3 phase power mesurements?
I assume that you mean 'watt meters', and not 'wave meters', in this question, and that you are referring to the 'two wattmeter method' of measuring the power of a three-phase load.Variations in power-factor will cause the ratio of the two wattmeter readings to vary, but the sum* of those readings will always indicate the total power of the load. Providing the load is balanced, you can use the ratio of the two wattmeter readings (P1 and P2) to determine its power factor, based on the following equation:phase angle = tan-1 {1.73[(P2 - P1) / (P2 + P1)]}Where power factor is then the cosine of the phase angle determined by this equation.[*If one or other of the wattmeters is reading 'downscale' -backwards- then it will be necessary to reverse the connection to that instrument's voltage or current coil.]
What are the two parameters that are necessary to determine probabilities for a particular normal distribution curve?
Mean and Standard Deviation
What is longitude interval logitude interval?
Longitude interval refers to the distance between two meridians on the Earth's surface, measured in degrees. It helps determine the east-west position of a location on the globe. The Earth is divided into 360 degrees of longitude, with the prime meridian (located at 0 degrees) serving as the starting point.
In what book do we find the scripture readings that are used in mass?
The Lectionary contains all the readings for Mass, for the two year cycle for daily readings, and the three year cycle for Sunday readings.
Lines running between the two poles are called as?
The lines running between the two poles are called meridians. These meridians are used in geographic coordinate systems to measure longitude and determine the angular distance east or west of the Prime Meridian (0 degrees longitude).
What is between every two minutes of longitude?
There are 15 degrees of longitude between every two minutes of longitude. Each degree of longitude is divided into 60 minutes.
