because there is a different amount of air in them.
A pan balance.
You would typically measure an encyclopedia in grams, as kilograms are typically used to measure heavier weights. A typical encyclopedia would not weigh enough to be measured in kilograms.
No. Balances measure weight. To measure a stick, you would use a ruler or similar measure.
an experiemnt to measure that would be to do something to compare the average spee of a certain age or height what you would use to measure would be like a stop watch
You can not directly compare mL and grams. mL is a measure of capacity where grams is a measure of weight. In order to compare the two, you would need to know the density of the substance you are working with.
In metric it would be measured as fractions of a gram. In US and British weights it would be measured in terms of grains (1/7000 of an ounce) or drams (1/256 of an ounce.)
A bar graph would be best to compare the atomic weights of different elements, as it allows for easy visual comparison of values. Each element could be represented by a separate bar, with the height of the bar corresponding to the atomic weight of the element.
A box plot would be an effective choice for showing the weights of several kinds of birds, as it can display the median, quartiles, and potential outliers within the data. Alternatively, a bar chart could also be used to compare the average weights of each bird type visually. If the data includes individual weights, a scatter plot could highlight the distribution and variation among the weights of different bird species.
mcg stands for micro gram (1/10,000th of a gram)...an accurate scale designed for small weights would do the trick.
An hour is a measurement of time, while a kilometre is a measure of distance. Without a measure of speed, it is impossible to compare the two.
I would say measure it, then compare it with the rest of the nation by finding out men's sizes online.
The way they would use it was for measuring wheat in a granary. They would then take wheat and crush it into flour. Then they would use different sized weights to measure the amount of flour and then the flour could be used for trading like money. To tell how much it cost, they just weighed it.
