Anil Shrestha IB Physics Labwork FINDING YOUNG’S MODULUS OF WOODEN METRE RULER INTRODUCTION: Young’s modulus is also known as tensile modulus. It is the measure of elasticity and it is a very important characteristic of a material. The formula of young’s modulus is stress by strain. In this experiment I am going to determine the young’s modulus (E) of wood from the period of oscillation of a loaded wooden ruler. Equation relating the period of oscillation t to the overhanging length l of

simply by adding a prefix in front of the basic unit: Unit prefixes: • kilo (k) = Makes the basic unit 1000 times larger (103) • deci (d) = Makes the basic unit 10 time smaller (10-1 or 1/10) • centi (c) = Makes the basic unit 100 times smaller (10-2 or 1/100) • milli (m) = Makes the basic unit 1000 times smaller (10-3 or 1/1000) • micro (µ) = Makes the basic unit a million times smaller (10-6 or 1/1‚000‚000) For example‚ a person might weigh 63‚000 grams. That same person also weighs

The hydropolis underwater hotel and resort is a proposed underwater hotel in Dubai . The hotel’s original plan was to be located 20 meters under water off the coast of Jumeriah Beach. The hotes plan is to cover an area of 260 hectares which is equivalent in area to Hyde Park in London . The construction cost of Hydropolis is approximately $550 million US dollars ‚ which will make Hydropolis one of the most expensive hotels ever created . The hotel design was created by Joachim Hauset and Proffessor

Unit 4 Lab Assignment Data Collection & Unit Conversions To complete this lab you must first collect data by interviewing friends‚ family‚ coworkers‚ neighbors‚ etc. You can conduct these interviews via personal visit‚ phone call‚ social media‚ however you choose. Ask your subjects the following questions: 1. What is your height? 2. Approximately how much do you weigh? If you prefer not to give your weight‚ how much does your bag (purse‚ back pack‚ lunch bag‚ etc.) weigh? 3. What is the furthest

Landslide Case study- La Canchita La Conchita is a very small community‚ located on the southern California coastline between Ventura and Santa Barbara. The community lies on a narrow strip of land about 250 meters (820 feet) wide between the shoreline and abutting a 180-meter (590 ft) high bluff. The top of the bluff is covered by avocado and citrus orchards. The bluff above La Conchita has a slope of approximately 35 degrees and consists of poorly cemented marine sediments On March 4‚ 1995

The forest lake aquathon consists of a 250 meter swim and a 2.5 kilometre run. A specific training program has been made to improve my weaknesses and work on cardiovascular fitness and endurance. This essay will also evaluate the personal training program that has been created and whether or not it will help improve my fitness. In last year’s aquathon I did not participate‚ but the average time that most students finished were around 20 minutes. There was also a fitness test where students swum

When you flip a light switch‚ the light seems to come on almost immediately‚ giving the impression that the electrons in the wiring move very rapidly. Part A: In reality‚ the individual electrons in a wire move very slowly through wires. A typical speed for an electron in a battery circuit is 5.0x10 to the -4th meters per second. How long does it take an electron moving at that speed to travel a wire 1.0

My First Triathlon Have you ever watched or attempted to complete an Olympic triathlon? They are exciting to watch; difficult to take part in‚ and extremely rewarding once you have finished. The race consists of three parts; the swim of 1500 meters‚ the biking of 40 kilometers‚ and the run of 10 kilometers. I did my first triathlon last summer and here is how it went. The swim is first. Fifteen hundred meters is not easy to visualize but if you can think of sixteen football fields in line
