PK-S Lab 03 – Lab Report Name: ____________________ Section: ___________________ EXPERIMENT 3: Trigonometric Measurements Procedures: 1. Experimental measurement of the angles and sides of a right triangle: A. Create a triangle by taping a string against a wall and taping the bottom of the string to the floor or a table set against the wall. Make sure that the wall is perpendicular to the floor or table by measuring angle C, which should be 90o. B.
Record the readings of the three instruments at eight different speed settings of the tunnel: 15, 20, 25, 30, 35, 40, 45, & 50. 4. Plot two calibration curves with pressure transducer reading as the abscissa and micromanometer reading as the ordinate for the first, and micromanometer versus scannivalve as the second. Convert micromanometer data to read as total pressure in SI units [Pa]. 5.
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.

Speed of sound in air using Resonance Purpose: In this laboratory investigation, we will determine speed of sound using the formula: speed = frequency times wavelength. Equation 1 After making several measurements of the speed of sound, we will compare our average experiment result from this lab to the speed of sound predicted by the equation vsound=330 m/s+.6m/s (T).Equation 2 Theory: Congitudinal waves are waves which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport. The result of a longitudinal wave is the creation of compressions and rarefactions within the air. Picture: The speed of sound in air is impacted by the temperature because sound travels by vibrating molecules and passing the energy on to a nearby molecule. Sound travels faster through warm air than cold air because the molecules in warm air vibrate faster.
Initial rates of solutions of the same consistency were determined by measuring the optical rotation angles at various temperatures. The data obtained was used to construct an Arrhenius plot and the activation energy for the reaction was determined. The values obtained through this experiment are as follows: α(0)=4.42 ± 0.06˚, α∞=-1.355 ± 0.001˚, k2cE0= (3.00 ± 1.15) x 10-4 (M/s), Km=1.1 ± 0.4 x 10-1 (M), and k2=(3.60 ± 1.38) x 10-4(s-1). INTRODUCTION In the study of chemical kinetics, the rates of enzyme catalyzed reactions are a significant area of interest as virtually all biochemical reactions are catalyzed by this class of proteins.1 For enzyme-catalyzed reactions, the basic mechanism as shown below in equations 1 and 2, was first proposed by Michaelis and Menten and then verified by a study of the kinetics of the inversion of sucrose.1 Eqn 1: E+S ES Eqn 2: ES E+P In this simple reaction mechanism an enzyme, E, converts a substrate, S, into products, P, through the initial formation of an enzyme substrate complex, ES.

Ex. D= length*repetitions=88*15=1320 cm 4) Once you have found distance find the velocity by dividing total distance by time Ex. V=dt = 132010 = 132 cm/s Wave Machine – Method 2 1) Measure length of wave machine and record length 2) Create a wave on the machine by each partner holding on to opposite sides and one partner gently flicks wrist 3) Time how long it takes 14 passes to occur and record this data 4) Next find the frequency by dividing events by time Ex. F = eventstime = 1410sec = 1.4 Hz 5) Now find landa ( ) Ex. 88cm = s 2 2(88)5 = 35.2 = 6) Finally calculate the velocity of the wave by multiplying landa by the frequency Ex.
