Science
The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.

If you know a car travels thirty km in twenty minutes you can find its what?
average speed, given by distance over time.
What is the metric system compared to us system?
Although USA is claiming following the SI units but it follows the British unit system. It is foot for length, pound for mass, and second for time.
When is 0.3 or 0.30 not equivalent in science It has to do with measurement but I am not sure?
0.3 is equivalent to 0.30 in the same way that 3/10 is equivalent to 30/100
im not 100% sure but anything that has mass and takes up space its matter
How do you measure liquid volume?
You can use some type of calibrated container: a graduated cylinder or beaker, generally. Another method would be to measure the mass of the liquid (any container will do, after you have tared the container) and divide by the density of the liquid (if you know it). These work for any liquid as long as it doesn't evaporate quickly. Also, the volume of a liquid may depend on temperature, so the volume at zero Celsius will be different from the volume at 98 Celsius, for example.
WikiLeaks is a site that publishes so-called classified information that has been leaked to it. By its very nature, we cannot establish the accuracy of such a site, because we (as mere mortals in this political game) do not have access to the original classified information, or the supporting documentation behind it. In point of fact, leaking of classified information has been going on for years, sometimes for good, sometimes for bad - and, interestingly, not all leaked information is accurate - it is sometimes deliberate misdirection - and we are left with no viable way to authenticate it either way.
In the final analysis, leaking of classified information is treason, and is potentially punishable by execution.
How many frempto seconds in a year?
First of all, the prefix is "femto...". It means 10-15.
There are 3.16 x 1022 femtoseconds in a year. (rounded)
We're guessing that your only purpose for posting this question on W.A.
was to see a big number. We aim to please, and will accordingly eschew
the convenience of scientific notation to bring you this number in all its
glory:
365.23 days = 31,555,872,000,000,000,000,000femtoseconds.
What is four and eight-elevenths times two and three-seventeenths?
The expression is given as:
4 8/11 * 2 3/17
Rewrite each term in improper fraction, so we have:
(4 * 11 + 8)/11 * (17 * 2 + 3)/17
= 52/11 * 37/17
Multiply the fractions altogether and simplify the product to get:
1924/187 = 10 54/187
What is the length and width of madame tussaud?
I consider this rather an impertinent question. It is not polite to ask a woman about her length and width.

What is 4 over 5 multiplied by 1 and 2 over 3?
When working with mixed numbers, it is usually easier to convert them to improper fractions, do the operations, and then to convert any resulting improper fraction back to a mixed number:
4/5 × 1 2/3 = 4/5 × (1×3+2)/3
= 4/5 × 5/3
= 20/15
= 4/3
= (1×3+1)/3
= 1⅓
