Carmela Marie C. Beloso Why Do I Want to Become an Engineer? Why do I want to become an engineer? Is a question I often ask myself and often have difficulty answering. When other people are asked with this question‚ they would have instant answers such as: It’s been my dream since I was little‚ I like machines‚ It’s because of LEGO.‚ My father is an engineer.‚ and etcetera. I wish I could have the same answer as them. I wish I could tell a story where when I was young‚ I would take my toys apart

Pendulum Problems ACTIVITY 1: Copy and paste the example problem and the steps‚ so that the steps are in the correct order into a new Word document and upload it to Moodle. Example Problem 1: A hypnotist swings her watch from 20.0cm chain in front of a subject’s eyes. What is the period of the swing of the watch. Thus‚ we see that the pendulum used by the hypnotist has a period of 0.898s. | Before we can use this formula‚ however‚ we must ensure all our variables are in the correct units.

TUTORIAL 1 1. Convert the following temperatures to their values on the Fahrenheit and Kelvin scales: (a) the boiling point of liquid hydrogen‚ –252.87°C (b) the temperature of a room at 20°C. 2. A constant-volume gas thermometer is calibrated in dry ice (–80.0°C) and in boiling ethyl alcohol (78.0°C). The respective pressures are 0.900 atm and 1.635 atm. (a) What value of absolute zero does the calibration yield? (b) What pressures would be found at the freezing and boiling points of water

International Biodiversity Conference 2010 VCAA EXAM With increasing prevalence of environmental issues on a global scale‚ controversy has risen from whether ‘we’ as humanitarians are taking responsibility for our actions. A transcript of Professor Chris Lee’s speech at the 2010 International Biodiversity Conference asserts that‚ ‘the time to talk is over‚’ and that now “is the time for serious action” to be taken towards making amends for the environmental damage and economical imbalance in

world. We chose physics as our topic of calculus application in real world because we believe that physics phenomenon is very common in our life. Physics is involved in many aspects of our life‚ such as driving‚ running‚ basketball‚ tennis‚ cycling‚ computers; many parts of our life involved physics. Companies such as automobile companies utilize physics to make their cars or motorcycles more aerodynamic‚ thus increase their speed. Cars are something that is closely related to physics since without

needed to pick something that was centered on physics. At first we were looking doing something towards space or the speed of light‚ but then Karina brought up the topic of roller coasters and it stuck. It really sounded like a fun topic to cover. In this essay we will be exploring the world of roller coasters. Some of the topics we will cover will be the history‚ the principles that allow the cars to continue throughout the length of the track‚ and the physics of roller coasters.
