developed an out of the box way of looking at things. And at the age of 24 he became the youngest scientist to become a part of the Manhattan Project, after the war he continued with his research which changed the codes of quantum physics and in 1965 he shared the Nobel Prize in physics with Julian Schwinger and Sin Itero Tomanaga . This is just a small part of the physicist's achievement. Feynman was a magician and such personalities are immortal their ideals cherished even decades after have physically

Question: “Theory: Drag for objects moving in a fluid (air is a fluid) has been determined to be D=1/2CpAv^2 where D is the drag force, C is the drag coefficient, p is the density of the fluid, and A is the surface of the body exposed to the fluid. Do your results support this relationship? Explain.” This equation does support the relationship of moving objects through a fluid, in this lab; air is the fluid being taken into account. The equation itself has many constants within it. The constants

Scalars are quantities that have magnitude only; they are independent of direction. Vectors have both magnitude and direction. The length of a vector represents magnitude. Scalars:-- temperature; (68 degrees, no direction) -- cost; ($37.50, Velocity is an example because you have magnitude and a direction (for example 30 m/s in the +x direction). Weight is a vector quantity because you have a force (the weight), and a direction (directed towards the center of the earth When sitting on a chair

THERMAL PROPERTIES OF MATTER Heat is a form of energy that is transferred from a hotter to a colder region by one or more of the following methods conduction, convection and radiation. When heat is given to a body one or more of the following may happen (i) Increase in temperature (ii) Increase in length ( area, volume) (iii) Change in state of the body Solid Liquid Liquid Gas (iv) Change in chemical composition (v) Change in electrical properties

Static Electricity; Electric Charge and Its conservation Static Electricity – amber effect, Electric charge Unlike charges attract, like charges repel. Two types of electric charge: positive and negative (amber). (By Benjamin Franklin) Whenever a certain amount of charge is produced on one object, an equal amount of the opposite type of charge is produced on another object. Net change in the amount of charge produced is zero. Charges are separated, but the sum of the two is zero. Law

Expansion Most substances expand when they are heated and contract when they are cooled. Heat causes expansion because it increases the vibrations of the atoms or molecules of a substance. The increased vibration forces the atoms or molecules further apart and the substance becomes larger, i.e. expands. When the substance cools down, it becomes smaller, i.e. contracts. Expansion and Contraction of Solids Solids expand in all directions when heated but the amount of expansion is usually

Introduction Last week we did an experiment on how does the volume of an container affect the mass required to make it awash in water.Some concerns we had were how would we know when it would be a good time to stop adding washers. Or how do we know our trials not change. The independent variable was the size of the beaker and the dependent was the number of washers that were needed. The controlled variables were the amount of gasses in the water because its tap and the temperature of the water.

America’s history of regulating private ownership of firearms goes back to the year 1791, when the Bill of Rights gained its final ratification. The Second Amendment of the Bill of Rights states, “A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed.". The true meaning of the Second Amendment is that we, as Americans, are guaranteed the right to keep and bear arms. This right must not be infringed upon.

Explain how a water filled graduated cylinder is inverted in a pan of water. The glass-collecting vessel is filled with water and covered with a glass plate or plastic wrap, which is to prevent air bubbles from getting into the vessel. The vessel is then flipped and placed into the pan of water where the glass plate or
