The purpose of this lab is to calculate bouyant forces of objects
submerged in water.
The first step in the lab was to measure the mass of a metal cylinder,
which was found to be 100g, and then to calculated it's weight, which was .98
newtons. Then next step was to measure the apparent weight of the cylinder when
it is completely submerged in a bath of water using the formula Wa=ma*g , this
was found to be 88.5grams. Knowing these two numbers, the bouyant force that
the water places on the object can be calculated using the formula Fb=W-Wa ,
Wa=.8673n W=.98n Fb=.1127n
Part 2 of this lab consisted of weighing an empty cup, which was 44grams.
And then filling another cup ...
As can be seen above, caffeine consists of two carbon/nitrogen rings with oxygen and methyl groups as substituents. The fused rings are similar to those in adenine only the substituents differ. Caffeine is found in coffee, tea, and many soft drinks. There is also some amount of caffeine in chocolate, as well as a closely related stimulant, theobr...
The Latin word for mushroom is (plural, fungi).

Included among the fungi, along with mushrooms, are molds, mildews, rusts, smuts, truffles, and yeasts. Toadstool is another name for...
There are many rainforests located throughout the world. Some of these rainforests are in danger. Among those which are being destroyed are the Nigerian Rainforests. These rainforests are endangered because of logging companies among a number of other things. Rainforests across the world are being destroyed everyday. These rainforests are being de...
The humpback whale is a baleen whale and a rorqual whale that sings amazing songs. It performs complex and cooperative feeding techniques. The humpback has a bulky head with bumpy protuberances (tubercles), each with a bristle. Humpbacks are acrobats of the ocean, breaching and slapping the water. They live in pods and have 2 blowholes.

The world's ocean covers about 70% of the Earth's surface. It is use to produce us many things. It is more than a place to swimming, sailing and other recreation. serves as a source of energy, raw materials and most of all food like fish and seaweed. In this essay I will talk about "What are our ocean resources and the importance of the oceans in...
