looking out for highly energetic gamma rays‚ as some has been found recently. The astronomers do know‚ however‚ that these gamma rays did not come from the same origin as the cosmic waves‚ as the gamma rays did not deflect off of the Milky Way’s magnetic field. Though they haven’t found the origin of these rays yet‚ astronomers are on the right path to get there. If it takes months‚ or years‚ they won’t rest until answers are given‚ thus expanding our small intergalactic knowledge. This article was

Most natural foods have a limited life. Perishable food such as: fish‚ meat‚ milk and bread have a short lifespan. Other foods keep a considerably longer time but decompose eventually. There are many causes

Magnetic Field Strength Determination on a Solenoid and Magnetic Field Mapping on Bar Magnets Sims‚ Jon Xyrus College of Engineering‚ University of the Philippines‚ Diliman‚ Quezon City Abstract Magnetic fields are important in a vast array of applications‚ as well as its natural occurrence in many different phenomena. This experiment aims to determine the dependence of its strength on both a changing current‚ and for a solenoid‚ changing number of turns and determine through linear regression

Ancient Food Preservation Methods Food preservation is a process used to save or delay foods from spoiling. These methods have been used before the beginning of written records. There were many ways that food was stored and preserved for future use and consumption. Although the ancient people lacked technology‚ they still understood the realization that the food they ate needed a process to keep their food safe to eat. This paper will help you better understand the use of food preservation technology

Induction using an oscillating wand which swings through a magnetic field. In addition‚ we studied the conversion of mechanical energy to electrical energy. Questions: 1. What are the possible errors in this experiment? There are a variety of sources of error which may have affected the results of this experiment. There could have been an error in the setup of the Rotary Motion setup or its setup within the Logger Pro program. Another issue with the setup could have occurred when using the banana

ratio ‚ of an electron using m Thomson’s bar magnet method. Basic methodology: Electrons in a CRT are deflected in the vertical direction by applying a potential between the vertical deflection plates of the CRT. A magnetic field perpendicular to the deflecting electric field is produced using a pair of bar magnets. The position of the magnets is adjusted so as to cancel the deflection of the electrons. The knowledge of the deflecting potential and the magnet field of the bar magnets leads to

FOOD PRESERVATION Food is preserved to prevent natural and microbial decay‚ by modifying the conditions that favour enzyme activity and the growth of micro-organisms. Foods are preserved for the following reasons: 1. To add variety to the diet‚ by making food available out of season. 2. To make use of food when it is cheap and plentiful and to store it for later use. 3. To vary the diet by preserving food in ways the make a new product out of the food (e.g. pickling‚ jam making).

Effect of The Earth’s magnetic field By X 9h Earth’s Magnetic Field Introduction Our Earth is a huge bar magnet tilted 11 degrees from the spin axis of the Earth‚ with geographic north pole being earth’s magnetic south pole and vice versa. Similar to how a magnet has a magnetic field surrounding it‚ our Earth also has its own magnetic field. The earth’s magnetic field is formed in the earth’s core due to a process known as the dynamo effect. According to dynamo effect
