Molecular mass

Background information: Breathing: They breathe oxygen through gills. Gills are respiratory organs found in aquatic organisms, which allow the Yabby to remove the oxygen from the water for respiration. Each leg has a gill attached, with the movement of the legs helping the circulation of water over these gills. There is a thin layer of exoskeleton separating the gills from the body cavity, allowing water to cover the gills without getting inside the body. Digestion: Digestive track includes…

Gaining Access Part of the reason the group chose St Stephen was because there was easy access. First and foremost it’s a public church; anyone can go and attend mass or talk to Father Ken if they want to. It’s especially easy for students to do so because it’s very close to campus and is practically all student run. Our group also had an inside connection with a member of the church which helped us to get a foot in the door. One of the member’s roommates is Catholic and goes to church every…

1) What are engineering stress and strain? Answer: Engineering Stress: Engineering stress is also called nominal stress, and it is defined as the applied load divided by the original cross sectional area of the material. Engineering Strain: Engineering strain is defined as the amount of material that deforms per unit length in a tensile test. Engineering strain is also known as nominal strain. 2) In the figure below, graphically show the toughness of three class materials:…

this experiment is the length of the string of the pendulum that could be changed. Dependent variable: The dependent variable is the time period for one oscillation. Constant/ Control measures: The constants considered in this experiment are: The mass, shape, size and diameter of the bob The amplitude (angle) at which the spring is gently left to oscillate. The path in which the oscillation takes…

The gym, it feels so natural, so free, like my new second home. My words when I went to the gym for the first time. I loved the gym. I wanted to be big and strong just like the people around. Yeah I didn’t fit in quite yet but how hard can it be? They all did it, so can I. So there I went, I started my first day at the gym. As many of you can see when you look at my arms that look like spaghetti noodles or my biceps looking like a bean my gym craze stopped after that first time. I lifted…

string. The airflow was also adjusted such that the glider moves freely with no friction. A photo-gate was also placed onto the air track, and this was connected to the computer program, LoggerPro. When the experimental arrangement was completed, the mass of the glider and flag was determined. For the first trial, no additional weights were added onto the glider + flag or the hanger. The air machine was turned on, and the photo-gate was positioned such that the speed of the glider could be…

Creatine Why do people workout? People usually workout because they are in a sport. In sports strength and endurance are vital. Working out helps an athlete to become better at sports. This is why many sports teams have early morning workouts and late night practices. This is usually widely practiced among teams through high school sports all the way to professional sports, it’s one of the best ways to become better. What other kinds of people workout?Normal people also workout to gain the…

1.0 Introduction The central teachings of traditional Catholicism are that Jesus is the Son of God, the second person of the Trinity of God the Father, the Son, and the Holy Spirit; that his life on earth, his crucifixion, resurrection, and ascension into heaven are proof of God 's love for humanity and God 's forgiveness of human sins; and that by faith in Jesus one may attain salvation and eternal life (infoplease.com, 2012). In Catholicism, the term scared means; The holy or divine. The…

During the course of this practical, the different factors of a pendulum will be investigated. A pendulum is a mass held from a fixed point so it is able to swing freely, the mass swings back and forth in an arc. The formula for finding the period of a certain pendulum lies in the change of the length of string suspending the mass, and the force due to gravity where the pendulum is being used. This relationship is shown in the equationT=2π√( L/g) (Sean, 2010), as the length of the string…
