CHAPTER 1 INTRODUCTION A. Background of the Study Generator has many meanings. However‚ this study’s definiton of generator is a program or software that generates something‚ in this case‚ tests‚ patterns and even format. Test generators can help you create your tests. With test generators‚ you can create multiple-choice and single choice questions all on the same test. You can also add images in question‚ scenario‚ choices and explanations varying on the type of test generatos used.

Van De Graaff Generator Construction and Working :- It consists of a large metal sphere mounted on high insulating supports. An endless belt b‚ made of insulating material such as rubber‚ passes over the vertical pulleys P1 and P2. The pulley P2 is at the centre of the metal sphere and the pulley P1 is vertically below P2. The belt is run by an electric motor M. B1and B2 are two metal brushes called collecting combs. The positive terminal of a high tension source (HT) is connected to the comb

VAN DE GRAAFF GENERATOR This is a machine that can build up high voltages of the order of a few million volts. The resulting large electric fields are used to accelerate charged particles (electrons‚ protons‚ ions) to high energies needed for experiments to probe the small scale structure of matter. Principle 1. Skin effect 2. Electrostatic induction 3. Action of points Construction A hollow metallic sphere A is mounted on insulating pillars as shown‚ and a pulley B is mounted at the centre

Types of DC Motors and DC Generators MOTORS – convert electrical energy to mechanical energy Motors and generators are the most frequent used electrical machines. ❖ Generators action can take place when and only when‚ there is a relative motion between conducting wires and magnetic lines of force. ❖ Electric motor is in operation when it is supplied with electrical energy and develops torque‚ that is‚ a tendency to produce rotation. ❖ In DC generator‚ the armature winding is mechanically

Importance of Eating a Balanced Diet And Maintaining a Sound Body Having a sound body is essential. One of the traits or characteristics of a balanced man is having a sound body and through the process you learn how to balance both sound mind and sound body. In order to achieve this one of the things I incorporate into my daily life is exercise. Whether it be a walk/jog‚ playing basketball or some type of sport‚ or even going to the gym to work out for a bit‚ I try to incorporate some type

What is the biggest animal ever to exist on Earth? By considerable measure‚ the largest known animal on Earth is the blue whale. Mature bluewhales can measure anywhere from 75 feet (23 m) to 100 feet (30.5 m) from head to tail‚ and can weigh as much as 150 tons (136 metric tons). That’s as long as an 8- to 10-story building and as heavy as about 112 adult male giraffes! These days‚ most adult blue whales are only 75 to 80 feet long; whalers hunted down most of the super giants. Female blue whales

Experiment 7: Velocity of Sound Laboratory Report Hazel Guerrero‚ Kyle Iddoba‚ Matthew Jocson‚ Thea Lagman Department of Biological Sciences College of Science‚ University of Santo Tomas Espanya‚ Manila Philippines Abstract Verification of the relationship between frequency of sound and its wavelength and the determination of the velocity and the speed of sound in different mediums was the main focus of this experiment. The speed of sound and its velocity was determined using the resonance

Lab Sheet 1. In the lab activity‚ you will examine sound waves as they are emitted from a moving source. Predict what will happen to the sound waves when the sound source is in motion. Record your prediction (hypothesis) as an “if then” statement. (For example: If you select the GO button‚ then the train will move) If the sound source is moving‚ as it get closer to the person it will get louder and the farther away it gets it starts to fade. 2. Select the boy icon. Select the lowest pitch by selecting

The coming of sound was an innovation to cinema that forever changed the way films were produced‚ viewed and performed. Sound plays many roles in the way a film is narrated and perceived by the audience. Sound‚ as defined in the Oxford Dictionary of Film Studies‚ ‘is central to the way in which a film establishes setting‚ shapes character‚ signposts its narrative‚ directs the audience’s and instils general emotional states’ (2012: 385). Sunrise: a song of two humans by F.W. Munrau was released in
