5. Compute a linear least-squares-fit of the calibration data and plot the resulting line on the same graph as the calibration data. Comment on the linearity of the pressure transducer and scannivalve. Part 3: Calibration of the Tunnel 1. Connect the micromanometer (calibrated in Part 2) across the wind-tunnel contraction in order to measure the static pressure drop.
Buoyancy Lab Report I. Theory: In this experiment, we are trying to prove a theory that buoyancy is a force exerted by a liquid, in this case water, which opposes an object's weight. The theoretical buoyant force is given by FB=ρgV with ρ is density (kg/m3), g is gravitational acceleration (m/s2), and V is volume (m3).To measure the buoyant force, we compare the weight of an object in and out of the water by FB=Wout – Win. The simplifying assumptions are no surface tension, no friction, no air resistance, and gravitational acceleration is constant at 9.8m/s2. II.
This light is lost in the cladding of the receiving optical fiber. Core diameter mismatch loss is typically only a concern with multimode optical fiber. To avoid core diameter mismatch make sure to check the cores of your fiber and make sure they are the same size to the best you can. Intrinsic factors that can affect connection performance in fiber-optics come in many types. A numerical aperture (NA) mismatch occurs when the NA of one optical fiber is different from the NA of the other optical fiber.
* Smart pulley, used at the end of the track as a pulley system between the bigger and smaller masses. Principles The principles used in the experiment would be Newton’s Second Law, which says that the behavior of objects under a net force is Fnet=ma, and net force is the sum of all forces acting on an object, Fnet=F. The experiment also uses principles of Tension “T” and the force of gravity “Fg”, which is equal to 9.8 m/s². Procedure Part A * Take the mass of the cart: 253.0 g * Add a 10g weight to the 1.0 g paper clip, making smaller mass 11.0g * Record the slope of the line of run #1 after releasing the cart to the end of the track. (y = 0.355x + 0.119) * Repeat with another 10g weight, making smaller mass 21.0g * Record the slope of the line after run #2 (y = 0.672x + 0.155) * Repeat with another 10g weight, making smaller mass 31.0g * Record the slope of the line after run #3 (y = 0.966x + 0.268) * Repeat with another 10g weight, making smaller mass 41.0g * Record the slope of the line after run #4 (y = 1.27x + 0.135) * Repeat with another 10g weight, making smaller mass 51.0g * Record the slope of the line after run #5 (y = 1.46x + 0.294) * Calculate the acceleration for each run using a =
The ideal gas constant value is 0.082057 (L x atm)÷(mol x K). The purpose of the experiment was to be able to measure the temperature and the mass of each gas tested, to configure a constant and determine which gas is the most “ideal”. To configure “R” the equation will be, R= PV ÷ nT. Based on our knowledge of an ideal gas, we hypothesized Pentane will have the most ideal behavior to real gas and Cyclohexane to be the least ideal. We expect Pentane to be the most ideal because it’s boiling point is the furthest away from the boiling point of water.
Physics 1408 Section E1 Standing Waves in a Vibrating Wire Callie K Partner: Miguel E Date Performed: March 20, 2012 TA: Raziyeh Y Abstract This lab had two purposes. The first was to determine the relationship between the length of a stretched wire and the frequencies at which resonance occurs. The second was to study the relationship between the frequency of vibration and the tension and linear mass density of the wire. In the first part we found the resonance, frequency and wavelength of a wire and used this data to calculate the speed of the traveling waves. For first harmonic, our wavelength was 1.200 m, found by the formula λ=2L/n.
The correct amount of product that can be produced is the smaller of the two values since that reactant limits the production of product. In this lab, the theoretical yield of the equation is found by using the type of stoichiometry problem mentioned above, and the actual yield is how much product is actually formed in the lab. The percent yield, a comparison between theoretical and actual yield, is than found using the equation: Percent yield = (actual yield / theoretical yield) X 100% Data and Calculations: Balanced Equation: CaCl2(aq) + 2NaOH(aq) Ca(OH)2(s) +2NaCl(aq) Table 1: Results Volume of CaCl2

- signs of chemical change = changes the shape and color, creates a gas, distributes heat, Etc. - Chemical Change= Substance is formed into a completely new substance 2. Hypothesis: If the copper is being tested in these metals ( Copper, Magnesium and cupric chloride) then it would be the least reactive out of magnesium and zinc because it is the lowest among the three on the activity series. 3. Experimental Design: - Independent Variable: different types of metals: magnesium, zinc and Copper - Dependent Variable: amount of reactants observed for each metal - Control : The Air -Constants: The amount of chemical solutions, the time the metals were in the chemical solutions and size of each metal during the experiment 4.
To use a lever, a person rests it on a support, the fulcrum, which is placed near the lower end of the lever and inserts it under the object to be lifted. The person pushes down on the upper end of the bar, the bar pivots on the fulcrum and the lower end is forced up. There are three classes of levers; class 1, class 2, and class 3. The trebuchet lever is a class 1 lever. A class 1 lever uses a fulcrum which is off center to
