experiment you can prove that electric charges can produce by using only a balloon and pieces of papers you can understand further static electricity and charges. And how it is produced. Introduction Have you ever wondered why rubbing a balloon make pieces of paper attract with it? The effect is due to static electricity‚ but how is the static electricity made‚ and why does it make pieces of papers attract in the balloon? Static electricity is the buildup of electrical charge in an object. Sometimes

be rubbed with a lightly colored-balloon for thirty seconds. Then the balloon will quickly be put on the wall and timed for how long it takes to fall down. Then it will be recorded and the results will need to be analyzed. The brunettes still held the most‚ but the blonds held less static electricity that the red haired people. The hypothesis was rejected in this experiment. Everyone loves to stick balloons to the wall with static electricity. Balloons are made of natural latex. Static

these stars have reduced numbers they still have distinguishing characteristics. These stars can go through different types of fusion than other stars‚ this allows the stars to still burn after all the hydrogen and helium have been used up. In this the high mass stars can create helium with hydrogen fusion‚ which means these stars can fuse large elements later in life. These stars also have an increased gravitational field‚ which produces the heat that starts the fusion. Fusion occurs more in a high

every action there is an equal and opposite reaction’ When a balloon is inflated plus released with no tying the inlet‚ the balloon flies all above the place as the air is released. The balloon and the air flowing out of the balloon travel in opposite directions. The Third Law of Motion states that every action has an equal and opposite reaction. This information can be used to create a balloon pinwheel. Tape the inlet of the balloon around the straw at the end opposite the flexible joint of the

MAGNETIC MAGNETIC REFRIGERATION a fruitful approach to reduce environmental pollution... ABSTRACT : The objective of this effort is to determine the feasibility of designing‚ fabricating and testing a sensor cooler‚ which uses solid materials as the refrigerant. These materials demonstrate the unique property known as the magneto caloric effect‚ which means that they increase and decrease in temperature when magnetized/demagnetized. This effect has been observed for many years and was used for cooling

THEORIES OF THE ORIGIN OF THE UNIVERSE 1. Steady State Theory – based on the perfect cosmological principle that the universe looks the same from any location at anytime. This theory holds that the universe is unchanging‚ it has no beginning and no end. 2. Big Bang Theory – presupposes that the vast universe grew out of something where all matter and energy were compressed to infinite density and heated to trillions of degrees (a beginning which was an immensely small particle of high-density

acceleration of which the water balloon is traveling causing it not to burst. When the balloon was dropped without a parachute the force of gravity was pulling it towards the ground therefore causing it to accelerating at such a fast rate that when it hit the ground the amount of force it hit the ground with was so great that the balloon popped. However when the balloon was dropped with a parachute‚ after deploying‚ it would provide wind resistance and therefore cause the balloon to decelerate causing it

the core of the disk that formed from the clump of gas that was compressed inside the gas cloud. The star becomes a stable main-sequence star‚ which are characterized by the source of their energy. They are all undergoing fusion of hydrogen into helium within their cores. The rate at which they do this and the amount of fuel available depends upon the mass of the star. Mass is the key factor in determining the lifespan of a main sequence star‚ its size and its luminosity. Stars on the main sequence

Lesson 3.01: History of the Periodic Table 1. Explain how scientific observations led to the development of‚ and changes to‚ the periodic table. Dmitri Mendeleev- first periodic table‚ organized 63 known elements according to properties‚ organized into rows and columns. He wrote names‚ mass and chemical properties on each. Julius lothar Meyer- independently worked in German ‚ similar to Mendeleev Henry Gwyn Jeffrey’s Moseley: worked with Ernest Rutherford experimented with 38 metals‚ he found that
