There are a 1000 pennies in a jar without removing any pennies explain how you can find the mass of one penny?

Answer 1

To find the mass of one penny without removing any pennies from the jar, you can use the concept of average mass. First, weigh the entire jar of 1000 pennies on a scale. Then, divide the total mass by 1000 to find the average mass of one penny. This method allows you to determine the mass of a single penny without the need to remove any from the jar.

Answer 2

the question is too vague

if you're allowed to use a good weighing machine then weigh the total jar and divide the answer by 1000 (saying the glass jar has negligible weight and the mass of air negligible)

if you know the mass of the glass jar then minus the total weight with the glass jars and then divide by 1000

otherwise if you're not allowed to use a weighing machine you can use the water method which would be a bit more complicated. (there are other method to find the weight using vacuum)

And moreIt's even more complicated than that! Not all pennies have the same mass, so the experiment is very ill-defined. Pennies (cents, really) made before 1982 have an average mass of 3.11 gm, while cents made after that year have a mass of 2.5 grams. If that's not confusing enough, cents specifically dated 1982 can have either mass depending on where they were made and at what time of the year.

IN ADDITION....

to answer the original question proposed. If you take the jar full of pennies and put it on a scale. Then add a single penny to the jar already full of pennies the weight will increase. This being done one can now subtract the added weight from the original weight of the full jar to find the weight of a single penny
