Million Years Ago Radio And Television
1,529 wordsMedia nowadays is considered a window for learning and is also considered to be our main window to the world. Media has evolved from simple text in papers, to voices in radios, to voices with pictures in television and movies, to the very broad and information packed Internet. But as we all know, media has changed and evolved since then. Media then was primarily used to deliver news across the town and to beef up the people with the information they need for their everyday life. Then, newspaper ...

Alpha Particles Nuclear Physics
758 wordsErnest Rutherford was born in New Zealand in 1871 as one of 12 children. It was Rutherford who first "split" an atom and who discovered the atomic "nucleus", a name that he invented. For this he is regarded as the greatest experimental physicist of his time. Rutherford was one of the first and most important researchers in nuclear physics. Soon after the discovery of radioactivity in 1986 by the French physicist Antoine Henri Becquerel, Rutherford discovered the three different types of radiatio...

Straight Line 5 Mm
1,125 wordsAim: I will investigate how the field strength varies the deflection of Beta Particles. Preliminary Work I started my preliminary work because, when I started my measurements using 2 coils used in experiments to deflect electrons from and electron gun. While testing for the deflection of beta particles, I found that beta radiation was scattered in a very large cone, I can not get any readings with amount of beta radiation scattering. So I would have to construct some type of shielding for this i...

Electric Field X 2
1,267 words... n line 3. Place the plates at 5 cm apart, using the set square making sure that the plates are 2. 5 cm form the centre line. 4. Turn on the EHT 5. Raise the voltage to 1 kV 6. Use the 10 second count, move the GM tube until there is a drop in the background count. Change to 100 s and move the GM slightly until you just get a back group count. 7. Record this result in the table. 8. Repeat step 5 to 7 increasing the voltage by 1 kV Analysis This experiment is similar to an electron gun experim...

Tricyclic Antidepressants Coronary Artery
4,629 wordsCardiac Location and Structures The heart is the driving force of the circulatory system, contracting about 70 times / minute to pump an adequate volume of blood with sufficient pressure to perfuse all body organs and tissues. The muscular organ, about the size of a clenched fist, weights from 300 to 400 g. It is located within the mediastinum of the thoracic cavity, above the diaphragm and between the lungs. This location subjects the heart? s activity to influence from all pressure variances d...

Inversely Proportional Power Supply
1,625 wordsParallel Plate Capacitor and Dielectrics Different materials were placed in between the plates of a parallel plate capacitor and the change in capacitance for each of the materials was tested using a galvanometer. The results were studied to determine the dielectric constant for each of the dielectric materials and to determine the permittivity of air. By its self, results show that the parallel plate capacitor? s capacitance is inversely proportional to the distance between the plates. This rel...

Big Bang Theory 20 Th Century
3,306 wordsAlbert Einsteins theory Relativity Relativity Albert Einsteins theory of relativity has caused major revolutions in physics and astronomy during the 20 th century. It introduced to science the concept of relativity the notion that there is no absolute motion in the universe, only relative motion thus superseding the 200 -year-old theory of mechanics of Isaac Newton. Einstein showed that we reside not in the flat, Euclidean space and uniform, absolute time of everyday experience, but in another e...
