Three objects greater than one kilogram are a pencil, a sheet of paper, and a paperclip.
So you can check your work afterwords. You know your answer is right if it is close to your prediction.
this might explain it better than i can :D check it outIs_a_cube_a_cuboid
Unless any of them are abnormally large, it should be common sense. But you could find a scale and weigh them.
method 1:start-run-input"cmd"-input"systeminfo" this method is check time from open up the PC power.(only this time) method 2:install hard disk software (for example:HDtune)check your HD so as to know how many hours it has run already .but the whole PC run time don't check. (I'm sorry.I'm a Chinese,my Englishi is very poor,but I hope you can understand my explain and ravel out your question.good luck!)
Yes - take the certified check back to the issuing institution along with your receipt and your personal identification, explain the situation, and I'm sure they will give you your cash back.
you weigh it
yes, because they use natural resources to check things such as air pressure, and what not
Airlines have different luggage allowances. You will need to check with the airline.
check
Airport security employees check for anything that could cause harm on an airplane such as sharp objects or objects that chemical capabilities like liquids.
So you can check your work afterwords. You know your answer is right if it is close to your prediction.
The universal standard for kilogram still stands in Paris. Copies have been made of the standard and every country has a duplicate of the kilogram for all the measuremeants. The copies are checked once in a few years to check if they are still accurate.
What distinguishes science from irrational belief is that scientific theories must be falsifiable. Falsifiability requires testing predictions which are made using scientific theory. A prediction that checks out adds support to the theory whereas a prediction that does not check out means that either the theory is faulty and needs modification (or scrapping), or that the theory was not used properly in making the prediction.
to use your head and explain what you solved
You have different kinds of methods for doing the a simple experiment in science. You need a prediction materials Observation Procedure and hypothesis for the experiment you do. 1st you make a prediction gather all the materials for your experiment and you start follow the experiment and last but not the least you have to check your hypothesis and prove it.........
When someone describes something as having a mass of one kilogram, it is important that everyone else understands what one kilogram is. Therefore there has to be an agreed definition of a kilogram. This means there has to be a standard kilogram that everyone can use to set their own kilogram. At present the standard kilogram is a block of platinum held in Paris, there are plans to redefine the kilogram in terms of the reaction between a fixed magnet and the magnetic field set up by an electric current passing through a wire, the kilogram will still weigh the same but the means of setting it will change.
To check what it is on a map check the legend of the map. It'll explain if not just ignore it.
