Assignment: Some governments say how many children a family can have in their country. As they control the number of children someone has through taxes. It is sometimes right for the government to control the population this way. Do you agree or disagree?

THE NATURE OF LIGHT Until the time of Isaac Newton (1642–1727)‚ most scientists thought that light consisted of streams of particles (called corpuscles) emitted by light sources. Galileo and others tried (unsuccessfully) to measure the speed of light. Around 1665‚ evidence of wave properties of light began to be discovered. By the early 19th century‚ evidence that light is a wave had grown very persuasive. In 1873‚ James Clerk Maxwell predicted the existence of electromagnetic waves and calculated

Chapter II Light and Matter The Inner Workings of the Cosmos 2.4 The Distribution of Radiation All microscopic objects – fires‚ cubes‚ people‚ and stars – emit radiation at all times. They radiate because the microscopic charged particles in them are in constant random motion‚ and whenever charges change their state of motion‚ electromagnetic radiation is emitted. The temperature of an object is a direct measure of the amount of microscopic motion within it. The hotter the object

Physical Light and Spiritual Light In this discussion‚ there are two kinds of light that are going to be compared. The two kinds of lights that are going to be compared against each other in this discussion are going to be; physical light and spiritual light. As we all know‚ the sun‚ stars‚ oil lamps will all eventually burn out‚ whereas the light of God is forever‚ so showing that spiritual light‚ God’s light‚ is much better than physical light. In Genesis 1:3 God said let there be light and there

they were able to attract each other light objects. He called this strange behavior electricity‚ from the Greek word elektron‚ meaning amber. II. WHAT IS STATIC ELECTRICITY? How is electricity produced? Have you ever noticed how your hair stands straight and stiff when you comb it vigorously on a dry‚ cold day? Or how difficult it is to remove dust particles from your comb? Your hair and the comb become charged by rubbing. This stationary electric charge is described as static electricity. Activity

HVDC LIGHT TECHNOLOGY ABSTRACT [pic] Transmitting power at high voltage and in DC form instead of AC is a new technology proven to be economic and simple in operation which is HVDC transmission. The HVDC (High Voltage Direct Current) technology is used to transmit electricity over long distances by overhead transmission lines or submarine cables. It is also used to interconnect separate power systems. A further development in this technology is HVDC
