I'm pretty sure pennies aren't magnetic but paper clips are so just use a magnet!
Anaphase
No. A US cent minted after 1983 starts out life as a zinc disk that is then "upset"
No, it's a physical change because you can still separate the two from each other.
Ridges, called spreading centers, happen where two plates move away from each other. As the plates separate, molten mantle material (magma/melted rock) flows up to fill the void.
The weight of a single penny is approximately 2.5 grams, or 0.00551156 pounds. Therefore, 8 pounds of pennies would be equivalent to approximately 1450 pennies (8 / 0.00551156). In terms of monetary value, each penny is worth $0.01, so 1450 pennies would be equal to $14.50.
Do it with metal paperclips: they are inexpensive and you can't damage anything when soldering them. Also use hook joints for stable mechanical joints before soldering.solder 4 paperclips together to make a squaresolder another 4 paperclips together to make a second squaresolder another 4 paperclips, one to each corner of one of the squares already made, perpendicular to the plane of the squaresolder each corner of the other square to the remaining end of those paperclips
A billion pennies stacked on top of each other would be 963.13 miles high
No. They are two separate countries that neighbor each other.
The distance to the moon is approximately 238,855 miles. If you stacked pennies on top of each other, a single penny is about 0.06 inches thick. You would need roughly 477,710,000 pennies stacked on top of each other to reach the moon.
Nope - merge and separate are opposites of each other.
Molecules in a liquid can move past each other, if that's what you were trying to ask; I'm not sure what "separate past each other" is supposed to mean.
Depends on which pennies. The NEW US penny weighs 2.5 grams each. The older copper penny weighed 3.11 grams. Pennies from other countries have different weights.
yes
separate them
Try to see if a paper airplane will fly farther with 5 paperclips on the nose as opposed to 0,1,or 3. Question: Will the # of paperclips on the nose of a paper airplane cause the plane to fly farther? Hypothesis: 5 paperclips on the nose of a paper airplane will make he plane fly farther than with 3,1,or 0 paperclips on the nose. Experiment: Make paper airplanes and fly them with 0 paperclips on the nose. Repeat this test 3 times. Record about how many meters each test flew. Repeat this with 1 paper clip, than 3 paperclips, and finally 5 paperclips. Analyse: Record the average of the 3 tests. write down the steps you took in completing the experiment. Also write down the controlled, dependent, and independent variables of the experiment. Conclusion: 5 paperclips on the nose of the paper airplane will make the plane fly farther than with 0,1,or 3 paperclips on the nose. Compare: Compare the averages, variables, and steps taken along with any other data, to that of other scientists. Remember, a valid experiment can be repeated with duplicated results.
Two pennies stamped from the national mint, indistinguishable from each other.
You would get 10 pennies for 2 nickels, as each nickel is worth 5 pennies.
