Jashandeep Gill Gammellos Chemistry Density is one of the fundamental principles of physics. Density is the reason why a plank of wood floats on water while a piece of metal several times smaller will sink. Density of an object is measured in g/cm³ or g/cc. The equation is D=M/V‚ D being the density of the object‚ M being the mass of the object‚ and V being the volume of the object. Mass is the space an object takes up. It is the amount of matter present in an object. Mass is measured using

Competition in school is harmful to the students. As unglamorous as it sounds‚ the purpose of a public education is to prepare the young person to enter the workplace as a fully functional worker. Competition encourages rugged individualists. The workplace needs team players who will cooperatively work together to meet common goals. The workplace does not need a group of stars who will not share the bonus and who work alone rather than working together. The more successful competitor‚ winner‚

In my writing‚ I normally make it up as I go along‚ in fact‚ I’m doing it right now‚ but this stops my brain from trying to plan everything out. I write in the heat of the moment because if I don’t‚ I get jammed and can’t even manage to write a single word. So‚ in light of this writing is a very difficult skill for me‚ especially when it isn’t something that I can just pour a bunch of facts into. Due to this complication‚ papers about my own reflections don’t come easy to me. It doesn’t help that

Acadamy at the time. It wasent untill 2000 years after no one questioned the theory of atoms‚ untill the early 1800’s. John Dalton was born in 1766 in Cumberland‚ England. Dalton made many experiment strictly to atom study even though he had no idea what is was. He is most known for the extensive research on atoms. He proposed a table of atomic weights for the number of the known element. This image is Dalton’s table of elements and the number of elemental combinations described in his 1808 publication
