a is. For this experiment, you will be filling plastic sandwich bags
about 2/3 full of water. Then you will take a sharp wooden pencil and poke it
ALL the way through the bag (and water). Poke pencils through the baggies
over a sink or outside. Try to see how many you can get through. For a
variation, you can also try pens or mechanical pencils to see what works or if
one prevents leaks better than the others. If it's nice out, consider doing this
experiment outside!

Concicina. I as your hypothesis correct?

the movie was based there, and all the animals and characters are native.

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.      

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
