At the equator, both longitude and latitude measure approximately 60 nautical miles. This converts to 69.046767 statute miles.
Both latitude and longitude degree lengths change with respect to latitude; latitude however changes very minimally between the equator and the poles, the distance only changes by about 75 meters between 0 degrees (the equator) where the degree length is 110574 meters, and 90 degrees (the north pole) the degree length of latitude is 111694 meters (note: miles = meters/1609.344)
Longitude however changes quite a lot from the equator to the poles, at 90 degrees the degree length of longitude is 0, where as at the equator it is 111320m.
There are a number of ways of finding the degree length, for close enough approximations it is usually said that the degree length of latitude does not change, lets say it's=111132m (it's that around 45 degrees of latitude), and degree length of longitude is then computed as:
L - latitude in radians
Longitude = 111132*cos(L)
(note: here that since its a trig function you have to convert degrees to radians, which can be done with radians = degrees*pi/180)
A much more close approximations for arcdegree lengths, based on an ellipsoid earth are:
(Radii based on WGS-84 ellipsoid, used by all current GPS devices)
E - equatorial radius - 6378137
P - polar radius - 6356752.314
L = latitude in radians
Latitude = (pi/180)*((PE)2/((E*cos(L))2+(P*sin(L))2)3/2)
Longitude = (pi/180)*cos(L)*(P2/((E*cos(L))2+(P*sin(L))2)1/2)
What is the difference between a gas and an element?
The two aren't really comparable in a "what is the difference" sense, because they sort of but not really overlap.
A gas is something that is in the gas phase. I know that's a little circular, but there you have it. Gases have no definite shape or volume.
An element is something that is composed entirely of atoms having the same number of protons.
Elements can be gaseous (and all elements are gaseous at a high enough temperature and low enough pressure).
How much time difference between Rhode Island and Singapore?
Rhode Island is typically 12 hours behind Singapore. For example, if it is noon in Rhode Island, it would be midnight in Singapore.
Some possible reasons for discrepancies in measurements could be human error in recording or taking the measurements, variations in technique or tools used, differences in interpretation of where the measurement should be taken, or discrepancies in calibration of measuring instruments.
What is the difference between conductor and dielectric?
Conductors conduct electricity or heat, energy a Dielectric is essentially an insulator.This has nothing to do with juvenile literature. by the way, waxed paper has a Dielectric of 540,00 Volts per Cubic centimeter, as determined by l909 engineering manuals. I will not reveal how I learned that!
No. Examples: Solid - water - noble gas
Copper has a density of 8950 kg/m3 = 8.95 kg/dm3 = 8.95 g/cm3.
Water has a density of 1000 kg/m3 = 1000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL.
Helium has a density of 0.1785 kg/m3 = 0.1785 g/L = 0.0001785 kg/dm3 = 0.0001785 kg/L =
0.0001785 g/cm3 = 0.0001785 g/mL.
AR steel, short for Abrasion Resistant steel, is a type of high-strength steel that is designed to resist abrasion and wear. It is commonly used in applications such as mining, construction, and manufacturing where materials are subjected to harsh conditions that can cause wear and tear. AR steel is often alloyed with elements like carbon, manganese, and boron to enhance its hardness and durability.
What is the difference between nematodes and annelids?
Nematodes are roundworms with smooth bodies and a lack of segmentation, while annelids are segmented worms with ring-like divisions along their bodies. Annelids also have bristles called setae on their bodies, which nematodes lack. Additionally, nematodes have a protective cuticle covering their bodies, while annelids do not.
How do acids and bases differ?
Acids release hydrogen ions in water, lowering the pH below 7. Bases accept hydrogen ions or release hydroxide ions in water, raising the pH above 7. Acids can be corrosive and sour-tasting, while bases can be slippery and bitter-tasting.
What is the difference between magnification resolution?
Magnification refers to the increase in apparent size of an object, while resolution is the ability to distinguish between two separate objects. Magnification is about making an object bigger, while resolution is about how clear and detailed the image is.
Being randomly assigned to the experimental condition in a research project involves being assigned?
to a specific group in an experiment where a particular treatment or intervention is applied. This allows researchers to compare the effects of the treatment to those in a control group. Random assignment helps ensure that participants are equally distributed across conditions, reducing the likelihood of bias in the results.
What is the water content of peanuts?
The water content of peanuts is estimated to be about 8 percent. Peanuts are said to be legumes which are rich in proteins.
What is the difference between laws and theories?
Laws describe observed phenomena and relationships in nature, while theories explain why those phenomena occur based on tested hypotheses and evidence. Laws are more descriptive and specific, while theories are broader and provide a framework for understanding natural phenomena.
What is the difference between distillation and fermentation?
what is the difference between fermentation and distillation?
Distillation- the separation of alcohol from a fermented liquid by heating to vaportize the alcohol, then condensing the vapors.
Fermentation- The action of yeast upon sugar in a solution, which breaks down the sugar into carbon dioxide and alcohol
What is the difference between voidage and porosity?
"Porosity" can be used to refer to voidage of a granular material. Pporosity could also denote the relative volume of pores, cracks and spaces in the solid body, while voidage deals exclusively with the amount of spaces between particles in relation to the overall volume occupied by the granular material.
Porosity is measure of void spaces in a material.voidage means the relative amount of space between materials that are tightly packed ..........
What is the difference between an isotonic solution and equilibrium?
An isotonic solution refers to a solution where the concentration of solutes is the same inside and outside of a cell, leading to no net movement of water across the cell membrane. Equilibrium, on the other hand, refers to a state where there is a balance between opposing forces, resulting in a steady state with no net change. In the context of a cell, equilibrium can refer to the balance of ions or molecules inside and outside the cell.
Why is the Induced fit model better than the lock and key model?
The induced fit model is considered better than the lock and key model because it takes into account the dynamic nature of enzymes and substrates, allowing for more flexibility in enzyme-substrate interactions. This model suggests that both enzyme and substrate undergo conformational changes to better fit each other, resulting in higher specificity and efficiency of the enzyme-substrate complex. Overall, the induced fit model provides a more accurate representation of the enzyme-substrate interaction compared to the rigid lock and key model.
Crustal instability refers to the tendency of Earth's crust to deform, break, and move due to internal forces such as tectonic plate movements. This can lead to earthquakes, volcanic eruptions, and other geological phenomena. The presence of crustal instability is a natural and ongoing process in shaping Earth's surface.
How do you determine the electronegativity of CCl4?
You can only get the EN (electronegativity) of elements (not for molecules, such as CCl4). For molecules you want DIFFERENCE IN EN. Easiest way is to look up the values in the chart. C = 2.5 , Cl = 3.0 so difference is 0.5 General idea is that EN increases left to right in the chart and decreases top to bottom in the periodic table. F (4.0) being the highest and Fr(0.7) being lowest
What is the closet star to earth?
Technically speaking, the sun is the closest star to Earth.
.
The next closest known star to the Earth is Proxima Centauri, red dwarf star
approximately 4.2 light years from Earth ... only about 278,000 times as far
from us as the Sun is. See the related link below for further information about
Proxima Centauri.
.
The next two closest known stars comprise the binary star system called Alpha
Centauri. Alpha Centauri is 4.4 light years from Earth.
.
It is postulated that another star, a red or brown dwarf star, closer to the Earth
than Proxima Centauri, orbits the sun in a highly elliptical orbit. This possible
star is code named Nemesis. See the related link below for further information
about a companion star.
That would be the Sun, an average everyday star. The next closest star to earth is Alpha Centauri, which is only four light-years away.
What is the difference between a definite and indefinite pitched instrument?
A definite pitched instrument produces sound at fixed frequencies that are constant at each position or setting. Example: a piano is a definite pitched instrament. When you press Middle C on the Keyboard the same tone occurs every time. "Digital sound is another example"
Where a indefinate pitched instrument is linear or analog in that there is no specific separation between notes. Trombones are a great example, because the slide allows the instrument to not only play a clear precise note such a Middle C, you can plan an near infinate numbers of tones between Middle C and C sharp by minute changes in the position of the slide.
Another way to look at it is, stairs versus ramps. You go up and down stair in measured amounts, no stopping between steps. A ramp has infinite points you can stop and start from.
Hope this helps.
What is the difference between infrasonic and ultrasonic?
Infrasonic refers to sound waves below the frequency range of human hearing (below 20 Hz), while ultrasonic refers to sound waves above the frequency range of human hearing (above 20,000 Hz). Infrasonic waves are often produced by natural phenomena like earthquakes, while ultrasonic waves are commonly used in medical imaging and pest control.
What is the defintion of solution?
A solution is a homogeneous mixture of two or more substances where one substance (solute) is dissolved in another substance (solvent). It is typically formed when a solute is completely dispersed in a solvent, resulting in a single phase. Solutions can be liquid, solid, or gas.
What is the difference between a meeting motion and a resolution?
The term 'resolution' is usually used to indicate a written statement, prepared in advance and available to the board to review before the meeting, which the board adopts. In simple terms it is a formal pre-written statement of the motion, usually preceded by the words "Resolved that..".
Robert's Rules of Order Newly Revised, 10th Edition says "For more important or complex questions, or when greater formality is desired, he presents the motion in the form of a resolution. The usual wording then is, `I move the adoption of the following resolution: Resolved, That..' A resolution of a long or complicated motion should be prepared in advance of the meeting, if possible, and should be put into writing before it is offered."
