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.

How do you find the volume of a irregular shaped object?
You use integration. That means you divide it into lots of smaller pieces; for example into thin, parallel slabs. For each slab you calculate the area, and multiply it by the thickness.If the slab has an irregular area, you may need to divide it into many thin strips - so you would basically do a double integration.
How many months and days would it take a jet to travel 821 million miles?
A jet flies at about 575mph, so we do this formula:
(1hour / 575mi) * (821,000,000mi) = 1,427,826 hours (About 2wks 2days 12hrs 37mins), assuming it could fly nonstop.
Multiply the 15 N you provide (note: that's a fairly small force for a human, even a baby could provide that) by the MA. That will give you the output force.To get the mass equivalent, assume a certain amount of gravitational acceleration (Earth's gravity is about 9.8 newton/kilogram), and divide the output force by that.
What is the average speed in km of a car a traveling at 380.0 in 2.42 miles?
There is something wrong with your units. Anyway, to calculate the average speed, you need to divide the distance by the time. If (for example) the distance is in miles, and the time in hours, then you get a speed in miles per hours.
Why is calculating square roots not taught?
It used to be taught many years ago but he advent of calculators and computers have essentially eliminated that. It is a good discipline to learn in school, however, so would be nice to be brought back, but unlike say, long division, it is a bit more complicated.
What does reversed and inversed mean?
Reverse means to exchange (the position or function) of two things:
49 reversed is 94
4 + 9 reversed is 9 + 4
Inverse refers to a reciprocal quantity or an element that, when combined with a given element in an operation, produces the identity element for that operation.
The inverse of 3 is 1/3 and vice versa.
Simple. In spite of his innate talent, his science and engineering classes fail to
engage his attention or spark his interest. He ditches classes and sleeps when he
does attend. He fails to produce passing work in them, and even though his potential
is stellar, grades are awarded commensurate with work, not potential.
It happens every day, and the consequences of a few years of that immature foolishness
follow the individual for the rest of his productive life. Trust me ... I should know.
State the function of immunoprotein?
An immunoprotein receptor is a blood protein. It plays a role in the efficient functioning of the immune system.
Technically, anything is divisible by three. 10 divided by 3 is 3.3333333333333...
But you probably meant whole numbers. There is an infinite number of numbers that can be divided by 3, such as 3, 6, 9, 12, 15...30, 33 and so on.
You can easily check if a number is divisible by three by adding its digits and seeing if the result is divisible by three. For example, 433 is not divisible by three because 4+3+3=10 and 10 is not divisible by three. Therefore, 435 is divisible by three because 4+3+5=12 and 12 is divisible by three.
What are the positive points of ulteraviolet rays?
Ultraviolet rays can be used as for fluorescent lamps as certain chemicals glow when they absorb ultraviolet.
In fluorescent lamps, the sindide of the tube is coated with a white powder that gives off light when it absorbs ultraviolet. The ultraviolet is produced by passing a current through a gas in the tube.
How chemistry is related to maths?
Math is used widely in chemistry as well as other sciences. Mathematical calculations are absolutely necessary to explore important concepts in chemistry. Without basic mathematically skills the calculation for chemistry would be extremely difficult.
Everything, that's all that chemistry is.
What is indepenedent variable?
an independent variable will not change with the amount of matter present. Think of it as being independent of the amount of material that is there
What are the irrational numbers?
Irrational numbers are numbers that cannot be expressed as a ratio of two integers or as a repeating or terminating decimal.
How do you convert inches into meters?
Since there are about 39.37 inches in one meter, just multiply meters by 39.37 to get inches.
