The Difference Between

Well, I could say that the length of the string, and how tight it is would affect the position of the harmonics. I can't provide an answer related to physics. There is a little problem in counting the harmonics and the overtones. So you find different statements in the internet. Some are wrong and some are right. Scroll down to related links and look at "Calculations of Harmonics from Fundamental Frequency".

Hi

Falling barometric pressure means the atmosphere at the barometer is becoming less heavy. It also generally means a storm of some sort is coming with inclement weather.

Here's a link to use for using a barometer and clouds to forecast the weather:

There are four levels of pitch in music: soprano, alto, tenor, and bass. In general, men's voices are tenor and bass and women's voices are alto and soprano, although the human voice can achieve all of these pitches when trained properly.

Many singers choose to focus on one particular range. This is why, in choirs, you find professional alto singers or soprano singers.

Each human has one natural range they fall into automatically.

Men and women have different hormones. Testosterone in a man causes the vocal cords to thicken therefore vibrating at a deeper resonating sound. Women have less testosterone and more estrogen causing the vocal cords to be thinner and making a higher pitch sound. This testerone effect explains why boys sing alto or soprano before puberty.

you can send anything into space to find the edge

but it will eventually end up where it started

it is impossible to find the edge of the universe

only scientists can predict the size of the universe

In essence there is no difference between a tester bottle and a regular bottle of cologne. When Cologne is shipped out to a store the manufacturer sends "tester" bottles of the fragrance so that the store has something the customer can sample. The difference between the two lies here, The tester bottle does not come in the nice packaging that the regular fragrance comes in, it is usually in a plain white box marked "tester". Generally the tester bottle will not have a cap either. As for the fragrance and the the volume of product all of that remains the same. i.e. If you get a 3.4 ml bottle of cologne and a 3.4 ml tester bottle you will receive the same product just in slightly different packaging.

Sulfer Dioxide is a chemical used in wastewater to remove chlorine from wastewater effluent, usually before discharging into a body of water. when placed in solution it creates sulfuric acid, which can be used for various laboratory tests. Also, when Sulphur Dioxide gas, released into the air, comes into contact with water, rain, they mix forming Sulfuric Acid [H2SO4] contributing to the acid rain problem.

Also, if an air breathing creature, including Man, breathes Sulphur Dioxide gas, it will combine with the water in the mucus in the eyes, nasal passages, windpipe, and lungs, again forming Sulfuric Acid, which can cause severe tissue burns, acute pulmomary edema [leaking body fluid], and even result in death. If one who is working heavily, and thus sweating profusely, comes into contact with Sulfur Dioxide gas, again , acid is formed, which will result in severe itching, burning of the skin, and within a few days, peeling of the outer skin layer(s), much like a very severe sunburn. === ===

Elements are distinguished based on their unique number of protons in the nucleus, which is known as the atomic number. Elements with different atomic numbers will have different chemical properties and behaviors. Additionally, elements can have different numbers of neutrons in their nuclei, creating isotopes of the same element.

The difference is a matter of thickness. For example steel PLATE is a large plate of thickness greater than 3/16 inch ( about 5 mm). Steel SHEET is plate that it LESS than 3/16 inch thick. And steel STRIP is SHEET cut into short widths.

These cutoff thicknesses may very between materials depending on manufacturing processes.

Hope this helps!

Firstly, with respect to your safety, always wear a laboratory coat and safety glasses. Before beginning an experiment, know the reactivity of the compounds or chemicals with respect to air and water. Also, when a chemical reaction occurs, poisonous gases may be released, so you must work in a fume cupboard (This will remove all poisonous gases)..

ANSWER

There are only two differences between RNA and DNA and that is the substitution of Thymine (in DNA) with Uracil (in RNA). Although DNA is mostly double stranded and RNA mostly single stranded, there are BOTH single stranded DNA and double stranded RNA amongst the viruses. It is one of the major levels used to classify viruses.

The other difference is, in DNA 2-deoxy-D-ribose is used in the spine while in RNA just plain D-ribose is used.

RNA is similar to DNA. There are a couple differences though. One is that RNA is single stranded and DNA is double stranded.

Lipids are nonpolar molecules, meaning they do not have a charge separation and are hydrophobic (repel water). This property is due to their long hydrocarbon chains that lack significant electronegative atoms, making them insoluble in water.

A tachogenerator is is an electric generator that generates a voltage that is accurately proportional to the speed of the shaft. Generating a voltage proportional to the speed is an inherent characteristic of all generators, but tachogenerators are specifically designed to provide an accurate signal over a specified range of load currents and operating temperatures. The output signal from a tachometer generator(tachogenerator) is often used to provide feedback to improve the regulation of an electric motor speed control.

A tachometer is an instrument that measures and displays rotational speed. An electric tachometer combines the tachogenerator with a voltmeter that has the dial marked to show speed rather than voltage.

Semen contains sperm, the male reproductive cells. Female discharge is a fluid that doesn't contain any reproductive cells.

True but how can you deteremine the difference if you found a fluid?

Table salt is sodium chloride combined with iodine sources (for nutrition), stabilizers for the iodine, and anti-caking compounds to make it pour by preventing it from absorbing water from the air.
Sodium Chloride (NaCl).

A molecule is 2 or more atoms bonded together. It could be the same element, such as H2 (hydrogen molecule) & O2 (oxygen molecule), or different elements, such as NaCl (sodium chloride - salt) or H2O (water)

Well. a village is only a smal collection of houses, lets say 100-200, A little like a hamlet exept a hamlet is only lets say 50 houses or even 7. A town is around 4000 or more. And finally a city has a chaplel and maybe over 10,000 or more.

^^ Actually, a city has a cathedral, and my village has about 2000 houses in :)

Noise (as related to a radio signal I suppose) is an unwanted signal being processed by a receiver. Attenuation is a loss of the intended signal before it gets to the receiver (usually due to such things as distance, line of sight obstructions, etc.

"Normal" air pressure varies a fair bit - the pressure used as "1 atmosphere" in calculations is ~101.3 kPa - this is from the "Standard Temperature and Pressure"

1 bar is 100 kPa, and 1000 millibars. Of course, I don't know where you are, so I can't account for pressure differences based on elevation or prevailing weather patterns. (Not being a meteorologist, I cannot even do the latter.) So your source for "normal" air pressure being 985 millibars is somewhat questionable, though still reasonable. (If you're talking about in-storm-system pressure, it becomes a lot more reasonable an assumption, though I'd double check it regardless.)

Now, in the eye of a tropical storm, Wikipedia's article on tropical storm eyes indicates the pressure may be as much as 15% lower than the air pressure in the rest of the storm (or a minimum reasonable pressure of 85% of the storm pressure. Their citation for this statement is "^ a bc Landsea, Chris and Sim Aberson. (August 13, 2004). "What is the "eye"?".

In hydrology, bound water, is an extremely thin layer of water surrounding mineral surfaces. Water molecules have a strong electrical polarity, meaning that there is a very strong positive charge on one side of the molecule and a strong negative charge on the other.

Speed is a scalar quantity that measures how fast an object is moving, whereas velocity is a vector quantity that measures both the speed and direction of an object. Both speed and velocity are measures of motion, but velocity includes information about the direction of the motion, while speed does not.

Rigor mortis is brought on by the release of calcium from the decomposing cells. It causes the the cross links in the muscle cells to link. As ATP is need for the release of the cross links the body remains stiff. (no ATP as body is dead) Rigor passes within 36hrs.

Heat stiffening is the shrinking of the muscles due to the coagulation of the muscle proteins. Think about frying beef, it shrinks. Heat stiffening lasts until the body begins to break down the muscles and only then will the body go flaccid. Rigor mortis doesn't occur.

Elements are pure substances consisting of one type of atom. A compound is made up of more than one type of element. Oxygen is an element but exists as a diatomic molecule by itself (O2). Carbon dioxide would be an example of a compound because it is made up of two different elements, carbon and oxygen (CO2)
yawa ka!

they differ because pure science is the study of a subject for the advancement of science and tecnology is the subject of electronic and technical objects and or materiALS. you're welcome ( : !
