A United States Quarter has a diameter of 24.26 mm and a Reeded edge of 1.75 mm. Both stacks below have 20 quarter each. Find the volume of stack of quarters.

16170mm^3

Explanation:

Find the volume of stack A

v=Bh

=12.13(35)

=16170 mm^3  (The /mm3 stands for cubic millimeter)

Find the volume of stack B

v=Bh

=12.12(1.75)

=808.517 mm^3 (The /mm3 stands for cubic millimeter)

= 16170mm^3

im pretty sure its none of them

all 4 come together due to gravity

all objects have gravity, even atoms

but their gravitational force is very low and it takes a long time for them to become closer together

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
