introduced to change the motion of the falling drop by an ionization source. By measuring the velocity of the oil drop under different conditions the amount of charge on the drop may be determined. If the charge on the drop is an integer multiple of the fundamental unit of charge (the electron)‚ then one will be able to confirm the quantization of charge. The charge carried by an oil droplet can be obtained by analyzing the forces acting on the drop under different conditions. In this experiment the terminal

In general‚ the ability of a substance to conduct energy‚ in this case heat‚ is directly related to its density. Air‚ being much less dense than the metallic substance‚ conducts energy to a lesser degree. It is also one of the fundamental properties of metallic substances to conduct energy which is related to its atomic structure. Also‚ air can get really hot‚ but it just can’t transfer that energy to someone hand as well as metal. Actually‚ aluminum pan or foil does get hot. In

The Puzzle of Emergence The puzzle of emergence is a very controversial and complex‚ scientific puzzle. This concept of emergence has been a baffling topic that has stumped many scientists and philosophers throughout the past centuries. George Henry Lewis was the first theorist to give wisdom to this puzzle in the late 1800s and so have many other theorists after this puzzle was first proposed. The term emergence can be defined differently in both a scientific or philosophical situation. It comes

Chapter 13 – States of Matter Pressure (P) – the amount of force per unit area. Pressure=F/a or P=F/a Pascal’s Principle “Any change in pressure at a point on a confined fluid is transmitted throughout the fluid”. Any change is transmitted throughout the fluid. Buoyancy & Archimedes Principle “When an object is submerged in a fluid‚ it displaces a certain volume of that fluid. The amount of force pushing upward on the object is equal to the density of the fluid (Ï) times the acceleration

za/grade-10/02-classification-of-matter/02-classification-of-matter-07.cnxmlplus A thermal conductor is a material that allows energy in the form of heat‚ to be transferred within the material‚ without any movement of the material itself. An easy way to understand this concept is through a simple demonstration. An insulator is a material that does not allow a transfer of electricity or energy. Materials that are poor thermal conductors can also be described as being good thermal insulators. Well-insulated buildings need

The fundamental modes of heat transfer are: Conduction or diffusion The transfer of energy between objects that are in physical contact Convection The transfer of energy between an object and its environment‚ due to fluid motion Radiation The transfer of energy to or from a body by means of the emission or absorption of electromagnetic radiation Mass transfer The transfer of energy from one location to another as a side effect of physically moving an object containing that energy Conduction

The physics concepts that were illustrated in our egg drop project were momentum and energy. In the project‚ we saw how momentum increases as a normal egg without anything to slow it down would crack. That was because the longer that the egg fell‚ the more momentum the egg gains. We also saw that by adding resistance during the fall‚ such as a plastic bag “parachute”‚ would slow down the egg enough so that it would not crack when it reached impact with the ground. The other concept that was discussed
