If you were lost at sea and needed to know your latitude where on earth would you not be able to tell?
You can always find your latitude and longitude by getting a 3-star celestial fix; as long as you have a sextant and an accurate timepiece.
If you are looking for a one-star observation to determine your latitude, then you would need to be able to see Polaris, the north star. Polaris cannot be observed anywhere south of about 3 degrees north latitude. (Polaris is not EXACTLY above the North Pole, so in order to get an accurate reading of your longitude, you would still need a nautical almanac and a watch.)
But with a watch, a sextant and a nautical almanac, you could do a "local apparent noon" observation of the Sun, and determine both your latitude and longitude quite precisely from one sighting.
What else can I help you with?
What would happen if gravity was weaker on earth?
People would be able to jump about 25 yards
If the earth's surface was an insulator and not a conductor would lightning be able to strike earth's surface?
No, if the Earth's surface were an insulator, lightning would not be able to strike it because insulators do not conduct electricity. Lightning occurs when there is a difference in electrical charge between the clouds and the Earth's surface, and if the Earth were an insulator, it would not allow the flow of electricity necessary for lightning to occur.
If a man could jump 6 feet on Earth how many inches high would he be able to jump on Jupiter?
With a stronger gravitational pull on Jupiter than on Earth, the man would be able to jump higher on Jupiter. On Jupiter, his jump would be approximately 18 feet high, which is equal to 216 inches.
How much explosive would it take to alter the position of earth?
Explosives would hardly be able to alter the position of earth. The only explosion that came close to altering the earth's position was from an asteroid that created 100 million mega tons of explosives.
If a metorite crashed onto the moon would you be able to hear it on earth?
No, you would not be able to hear a meteorite crashing onto the moon from Earth. Sound requires a medium, like air or water, to travel through, and space is a vacuum with no air. Therefore, any sounds produced by the impact would not propagate to Earth. Additionally, the distance between the Earth and the Moon—about 238,855 miles—would further diminish any potential auditory effects even if sound could travel through space.
What is the importance of latitude and longitude on a map?
Latitude and longitude are able to pinpoint a certain location on Earth accurately on a map.
Will you be able to see asteroid November 8 2011?
Yes, people were able to see the asteroid passing by earth. However, you would have needed a telescope, as you were not able to see it with the naked eye.
How does latitude and longitude help people find places?
They do not. The purpose of latitude and longitude is to give everyone an unambiguous way to describe any location on Earth, in a way that anybody else will be able to locate this same spot.
Why wouldn't you be able to travel to the centre of the earth?
the core of the earth is SOOOOOOOOOOOOOOOOO hot, that you would not be able to travel there!!!! It would also take a lot of igging!!!!!!!
Would artificial gravity on the iss eliminate the problem of muscle wastage and bone density problems on long stay mission?
Yes. If we were able to perfectly mimic Earth's gravity, our body would have to keep the bone and muscle, as it is needed.
If friction is vanished what would happen on earth?
We would not be able to walk and nothing would be able to stay still Hope I could help
How would the earth look without oceans?
Bare rock. We would not be able to see it. In fact there would be no life on Earth without water.
Would you be able to see Jupiter with a telescope from Earth at night?
Yes. You are able to see Jupiter with a telescope from Earth at certain points in the year.
Are you able to run faster on mars or the earth?
You would be able to run faster on Mars than on Earth due to its lower gravity. Mars has about 38% of Earth's gravity, so your weight would be less and you would be able to move more easily on its surface.
What would happen if there was no water on Earth?
If there was no water on Earth, all living things would die because water is essential for survival. Plants would not be able to grow, animals would not have anything to drink, and humans would not be able to survive without water. The Earth would become a barren and lifeless planet.
What would happen to daytime and nigtime if the earth did not spin on its axis?
we would be able to feel it
Would a human be able to survive in the center of the earth?
No the heat would be to much pressure
