A small mirror and lens makes the level bubble visible in the field of view. When the object is aligned with the crosshair in the sighting tube‚ the spirit level is rotated so that the bubble is bisected by the crosshair‚ as illustrated in the diagram. Then‚ the elevation of the line of sight can be read off on the scale. The Vernier can be read to 10 ’‚ but it requires

been covered you are to poke holes so you can insert the sensors. Next‚ you will cover the bottom of the “BioChamber” with one layer of turgid spinach leaves and proceed by connecting the Gas Sensor to Channel 1 and the O2 Gas to Channel 2 of the “Vernier computer interface”. Once the file “31C Photo (CO2 and O2)” is opened you can secure the lid on the chamber and insert the sensors into the holes that you previously made. After 15-minutes of data being collected you can observe the data. Now that

Regents Physics Constant Velocity/ Acceleration Lab 10-3-13 Problem: Graphical Analysis of Constant Velocity and Accelerated Motion. Theory: Gravitational acceleration is constant on Earth g=9.8m/s2 Therefore‚ when the golf ball is dropped‚ the acceleration will be equal to gravitational acceleration agb=9.8m/s2 Given there is no air resistance‚ this means that when the golf ball is dropped from a given distance‚ according to the formulas‚ the golf ball will accelerate

Experiment 2: Kinematics of Human Motion Abstract: Kinematics is the branch of classical mechanics that describes the motion of bodies (objects) and systems (groups of objects) without consideration of the forces that cause the motion. There are four activities done in this experiment. Graphical analysis of human motion‚ where displacement vs time and velocity vs. time were graphed. Graphical analysis of motion where in the 10th seconds the total displacement is 18.75m‚ average velocity

Solid Mechanics Lab Report Experiment to determine the Young’s modulus of an aluminium cantilever beam and the uncertainties in its measurement 1. Abstarct: The young’s modulus E‚ is a measure of the stiffness and is therefore one of the most important properties in engineering design. It is a materials ratio between stress and strain: E=σε Young’s modulus is a unique value for each material and indicates the strength of that material as well as how it will deform when a load is applied.

Fitness Testing Flexibility- For flexibility you can do the sit and reach test. The advantages of this are it is relatively cheap‚ not much equipment is needed apart from a box with measurements on and a magnet to move on it. A disadvantage for the traditional sit and reach procedure is that people with long arms and/or short legs would get a better result‚ while those with short arms and/or long legs are at a disadvantage. The modified sit and reach test controls for this‚ as the zero mark is

Investigation of Water Potential in a Root Vegetable Introduction Background Information: Osmosis is the passage of water from a region of high water potential to a region of low water potential‚ down a water potential gradient through a semi-permeable membrane. If a plant cell‚ or an item with similar properties is put in water‚ three different things can happen: • If the surrounding area has a higher water potential‚ the cell will increase in mass through osmosis. The cell will
