| Assignment 2 | Guide wavelength measurements | | | Abstract The purpose of this experiment is to demonstrate: a) The techniques for measuring guide wavelength. b) The relationship between the wavelength in free space and the guide wavelength. Furthermore‚ this experiment will be a way in which to gain experience in using different types of laboratory communications equipment. Introduction What is wavelength? Wavelength of a sinusoidal wave is the distance between identical

MEASURING ECONOMIC DEVELOPMENT PRIMER ON THE HUMAN DEVELOPMENT INDEX What It Measures The HDI is a composite of three basic components of human development: longevity‚ knowledge and standard of living. Longevity is measured by life expectancy. Knowledge is measured by a combination of adult literacy (two-thirds weight) and mean years of schooling (one-third weight). Standard of living is measured by purchasing power‚ based on real GDP per capita adjusted for the local cost of living

2.4 Galileo Galilei: Sixteenth-Century “New Scientist” 1. In your own words explain why Albert Einstein considered Galileo to be the “father of modern science” Albert Einstein considered Galileo to be the father of modern science because of how many of Galileo’s discoveries have become the basis of today’s science. 2. Why did Galileo choose to use a ramp to perform his acceleration experiment? Technology during Galileo’s time was still quite primitive. His experiment which required him to drop

This year in science‚ we were paired up in groups to build a car powered only by a rubber band. There was a lot of physics and thought put behind the planning of our car. The rubber band moved the car by storing up elastic potential energy which then turned into kinetic energy when released. Newton’s Laws of Motion also come in handy when thinking about how to keep the car moving. “An object in motion stays in motion.” There was also a lot of thought put into the wheels. We had to be aware of the

Review Complete the statement or answers the question. Which problems would NOT be a part of physics? A theory is A scientific hypothesis may turn out to be right or it may turn out to be wrong. If it is a valid hypothesis‚ there must be a test for proving that it is To test a scientific hypothesis you would Which of the following statements is not true? Which of the following is a reason to express scientific findings mathematically? Which has greater linear speed

Therefore the sum of all the energies in the system is a constant. TMEinitial=TMEfinal 3. Explain the basic ideas that govern the design and operation of a roller coaster. A roller coaster is operated and designed through the application of Physics. The law of Conservation of Energy governs the changes in a coaster ’s speed and height. Simply put‚ the higher an object is off the ground‚ the more potential energy it has - that is‚ potential to gain speed as it falls. As it falls toward the ground

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which
