What is the latin word for torch?
Answer There are actually possible several words. Olympic Torch would be Fax Olympica (fax facis facem); Olympic Flame would be Flamma Olympica (flamma flammae flammam).
No; however it can refer to many things including flower sepals, parts of a coral, kidney or brain, a UK D&B artist, a Greek semimortal, a journal or a fictionary moon.
In an elevator when is your apparent weight less than your real weight?
When the lift is accelerating downwards. See related question.
What is the data of the project egg flotation?
you'd have to look up a data graph, and put it in your own words.
The only elements in pure water are those of which water itself is comprised ...
hydrogen and oxygen. In impure water, any other elements that are themselves
soluble in water, or that are components of water-soluble compounds, or that are
ground up fine enough to be physically suspended in water, can also be found.
Why must at least two successive mass readings be equal before finishing the experiment?
In order for experiment results to be trusted, they must be both precise and accurate. Successive instrument readings help guarantee both of these.
Can you eliminate indeterminate errors in your experiment?
No, they cannot be eliminated. They can be greatly minimized to reduce errors though.
Determinate errorshave a definite direction and magnitude and have an assignable cause (their cause can be determined). Determinate error is also called systematic error. Determinate error can (theoretically) be eliminated.Indeterminate errorsarise from uncertainties in a measurement as discussed above. Indeterminate error is also called random error, or noise. Indeterminate error can be minimized but cannot be eliminated.

Nitrogen is the 7th element in the Periodic Table (Atomic number). It's located in the 2nd period and group IIIa (13) in the periodic table. It has 7 electrons: 2 in the K orbit, 5 in the L orbit.
Its symbol is (N) and its relative atomic mass is 14.01. Its electronegativity is 3.0.
Boiling point is -195.8°C, melting point -218.4°C, density is 1.85 at 20°C. Oxidation number is -II and electron configuration is 1s22s22p3.
It has hexagonal chrystal structure and a amphoteric acid-base property.
What are the steps to Separate a Mixture?
It all depends on the substance and its physical properties. For example, salt water can be separated by boiling the water and letting the salt remain.
What are some good science experiments that are in the 6th grade science book?
What is the difference in the hardness between glass and fiber glass
How long does it take to suck an egg into a bottle during an air pressure experiment?
About 1 minute...i think!
How many variables can be changed in an experiment?
It depends on the experiment or the category.
you welcome s.a
No it's the variable k.a.
If you turned on an empty microwave oven what would happen?
The light inside would turn on, the turntable would spin, the timer would count down, and this would all continue until the timer reached zero, at which time everything would shut off. Most manuals advise against doing this, because if there's nothing in the oven to absorb the microwaves they can reflect back and damage the klystron (the part that actually generates the microwaves).
What is a last minute science project?
Volcando, diagram of the human body, friction, etc.
gald u asked. im a sophomore who was in the same pickle. i did a reaction time lab. u get ppl to catch a falling meter stick. they hold their thumb and index finger apart, with the end of the meter stick just above their fingers. where they catch it is basically their reaction time. problem. this is not a "reaction time". u can prolly find a formula somwhere to convert it, or find a way to bypass this problem. well that's all i have, hope it helps :P
