It is solar noon at your unknown longitude What if your chronometer clock reads 8 am your clock is set to Pacific Standard Time at 120 degrees West Longitude So what is your longitude?
118 degrees 15' W
How do you install a standard sundial in the Southern hemisphere?
There is no such thing as a standard sundial. For every different latitude (degrees north or south) the gnomon (the triangular shadow making bit) has to be cut differently. If you live 30 degrees south, cut the gnomon to a 30 degree angle. Set up the sundial so the sharp end of the gnomon is pointing exactly North. The easiest way is to just twist the assembled sundial until it shows the right time. If you want to be as accurate as possible you need to take longitude and time of year into consideration as well, but as most sundials are simply ornaments, that detail is not given.
How long does the earth takes to rotate through 180 degrees of longitude?
180° is half of a full rotation, so the answer is half of a day or twelve hours (ignoring the variables that contribute to the equation of time offset).
Why was the invention of an accurate clock crucial to solving the problem of determining longitude?
It enabled the navigator accurately to compare the time of local mid day to the time of mid day at the Greenwich meridian. The time difference is directly convertible into a longitude reading.
A person knows the sun time on the prime meridian and the local sun time What determination can be made?
Longitude
How many degrees are in each standard time zone?
There are 15 degrees of longitude in each standard time zone
What are the degrees of the longitude of the Indian standard time?
82.5 E
What is the longitude and latitude of IST?
IST = India Standard Time The longitude bounds is 68 degrees East - 97 degrees East. The latitude bounds is 35 degrees North - 8 degrees North
How is local time and the international date line alike?
They go according to lines of longitude. For example, if a place is UTC +8, it is located along approximately 120 degrees east longitude, while the international date line is located at approximately 180 degrees longitude.
It is solar noon at your unknown longitude What if your chronometer clock reads 8 am your clock is set to Pacific Standard Time at 120 degrees West Longitude So what is your longitude?
118 degrees 15' W
Indian Standard Time is based on the longitude of 82.5 degrees passing through what places?
jaipur
How is longitude a function of time?
Every 15 degrees of longitude correspond to an hour of time. The sun will rise and set 1 hour earlier or later at 15 degree intervals. Time zones occur approximately every 15 degrees to compensate for this.
What is the longitude of world standard time?
ZERO 0 Longitude
What is the solar time of 72 degrees W longitude if it is noon solar time at 90 degrees W longitude?
10.48am
What is the hour and the date at 120 degrees east longitude?
England's Royal Observatory in Greenwich (the source of Greenwich Mean Time - GMT) is 0 degrees longitude and the reference point. 120 degrees East is the longitude of the east coast of Taiwan. At that longitude, 1/3 of a circumference from Greenwich, the standard time (and date) should be 8 hours ahead of Greenwich. So if it is 4am in Greenwich, it should be noon in Taiwan.
What is the difference between a prime meridian and a meridian?
The time meridian is each standard time zone roughly centered on a line of longitude exactly divisible by 15 degrees and the prime meridian is the starting point for the standard time zones an arbitrary longitude line.
Does longitude measure the time?
Longitude measures the angular distance of a place east or west of the meridian at Greenwich, England, or west of the standard meridian of a celestial object, usually expressed in degrees and minutes.
