Lab Assignment 4: Types of Force Instructor’s Overview In many physics problems involving Newton’s laws of motion, you’ll see statements like, “assume a frictionless surface” or “neglecting air resistance…” In this lab we will be exploring both friction and air resistance, two resistive forces that are critical in the design of real-world products and systems. Understanding the effects of these types of forces is essential in the design of such things as aircraft, automobiles, braking systems

composite particles we see around us today became possible, leading to a matter dominated universe, the first neutral atoms (almost all of them hydrogen), and the cosmic microwave background radiation we can detect today. Modern high energy particle physics theories are satisfactory at these energy levels, and so physicists believe they have a good understanding of this

Physics Homework, Unit 9 Deborah Williams 08/13/2014 Pg. 268-269-1. What is the source of wave motion? Answer: A wiggle in space and time. 2. If we double the frequency of a vibrating object, what happens to its period? Answer: Frequency and period are the inverse of each other. Frequency = 1/period or Period = 1/frequency 36. A railroad locomotive is at rest with its whistle shrieking, and then it starts moving toward you. a. Does the frequency that you hear increase, decrease

Physics h/wk. The Majestic Sombrero Galaxy The Sombrero Galaxy (also known as M104 or NGC 4594 ) is an unbarred spiral galaxy in the constellation Virgo located 28 million light years from earth. It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its inclined disk. The dark dust lane and the bulge give this galaxy the appearance of a sombrero. The galaxy has an apparent magnitude of +9.0, making it easily visible with amateur telescopes. The large bulge

VASILEIOS-MARIOS GKORTSAS vasilisg@mit.edu 6.638 Term Paper Attosecond Pulse Generation Abstract: The word “attosecond” (1 as = 10-18 sec) entered the vocabulary of physics when sub-femtosecond pulses of UV/XUV light were established. High harmonic generation (HHG) is currently the only experimentally proven method for generating attosecond pulses. Attosecond science has opened the door to real-time observation and time-domain control of atomic-scale electron dynamics. In this

Medical Imaging Physics- W. R. Hendee Chapter 7- Interaction of X and γ Rays in the Body A Summary submitted by Miles Que I. Introduction The dominant interaction of X and γ rays in the body depend of three main factors: electron density, effective atomic number and the photon energy. All of which, cause different reactions in the body which is divided into four regions: fat, muscle, air- filled cavities and bones. II. ƒ Factor As discussed in the previous chapters, an exposure of 1 Coulomb/
