What is the density of 10 pennies?
To find density you must first determine the mass and volume. Also, it matters if your penny or penny's are pre 1982 or post due to the metal they were created in. 10 post '82 penny's will weigh in approx. 25.0 grams. To get your volume = 3.14 X radius squared x height. In this case it would look like V = 3.14 x 9.5mm x 9.5mm x 1.27mm. Whereas V= 360 cubic millmeters. To get your density, we use Density = Mass/Volume. So Density=25\360, which equals .0694 g/cubic millimeters.
How can you calculate the thickness of 1 penny in millimeters?
You can get a stack of pennies, measure the height of the stack and then divide by the number of pennies. You can also get the thickness by treating the penny as a cylinder, calculating the area of the face of the penny, then putting a whole lot of them in water, measuring the change of volume to get the total volume of all pennies, then divide by the number of pennies and divide again by the area of the penny to get the thickness.
What is the volume of 200 pennies?
There are very many countries which use pennies as their minor currency units, including the US where, for some bizarre reason, a cent is also called a penny. The country is not specified. Assuming it is the UK and that the embossing adds so volume, 200 penny coins will have a volume of approx 107 millilitres.
How many pennies will it take to fill a 1.75 liter bottle?
To calculate the number of pennies needed to fill a 1.75 liter bottle, we first need to determine the volume of a single penny. A US penny has a volume of approximately 0.36 cubic centimeters. Next, we convert the volume of the bottle to cubic centimeters, which is 1750 milliliters or 1750 cubic centimeters. Finally, we divide the volume of the bottle by the volume of a penny to find out how many pennies will fit, which is approximately 4861 pennies.
What is the percentage of copper in a 2004 penny?
All US cents minted for circulation since mid-1982 are 97.5% zinc, plated with 2.5% copper.
