Investigations in Light Intensity Change through Angular Displacement Guiding Question How does the intensity of light change as the angle of incidence to the light source increases? Prediction of Results Predict what you think will happen and what type of equation and graph might best fit the data representing the intensity of a light as the angle of incidence increases. Objective After completing this lesson‚ a student should be able to analyze light intensity striking a surface at varying

Topic: Transport related to pollution Name: Course: Instructor’s Name: Date: Abstract Transport came to the lime light of the pollution debate after the issue of pollution from sooty smog from the burning of coal got to be solved. Since solving of the issue‚ emissions that ensue from the transport sector including motor vehicles‚ jets‚ and trains have been the main contributors to the pollution of the air. The effects of the emissions affect the urbanites health conditions‚ in addition

Light I | | INTRODUCTION | Light‚ form of energy visible to the human eye that is radiated by moving charged particles. Light from the Sun provides the energy needed for plant growth. Plants convert the energy in sunlight into storable chemical form through a process called photosynthesis. Petroleum‚ coal‚ and natural gas are the remains of plants that lived millions of years ago‚ and the energy these fuels release when they burn is the chemical energy converted from sunlight. When animals digest

Transport; Containerization Transport or transportation is the movement of people‚ animals and goods from one location to another. Modes of transport include air‚ rail‚ road‚ water‚ cable‚ pipeline‚ and space. The field can be divided into infrastructure‚ vehicles‚ and operations. Transport is important since it enables trade between people‚ which in turn establishes civilizations. The transport systems

greater understanding of the universe. Specifically‚ we gain better understanding of how the structure of the atom works‚ as we study the interaction of small particles which gives us a better understanding of the world. The data which we have on how electrons and atoms interact is gathered mostly on observations alone. For example‚ the properties of hydrogen atoms can distinguish between the different tissues and muscles within the human body‚ this is because the human body consists of 63% of hydrogen

Sir J.J.THOMSOM is to physics what electron is to an atom. He charged the world of physics with his discoveries and gave momentum to atomic physics. Physics is what today because of this British scientist who is regarded as the greatest experimental physicists of this century. A bookseller’s son‚ Thomsom studied at the Owens College and later at the Manchester University. He wanted to become an engineer‚ but his father’s death in 1872 forced him to study Mathematics‚ Physics and Chemistry as he
