Measuring the Speed of Sound (Moving Tube) KEY Purpose: To measure the speed of sound in air using a variable length column of air. Apparatus: resonance-tube apparatus (an open ended tube which can be moved in and out of a container of water) constant frequency source (tuning fork or computer generated tone) rubber hammer meter stick rubber stopper Procedure: 1. Set Up the Experiment: Place the open ended tube into the water‚ and verify that it can produce a resonance tube

Rev. 01/10 JEB GLASSWARE CALIBRATION 1. Objectives Verify the actual volume of liquid delivered by 2 different types of glassware devices. Evaluate which measurement method is better for different uses. 2. Techniques Buret use: Put the buret in a buret stand and approximately fill it with temperature-equilibrated water. Make sure that the tip of the buret is filled with water and that there are no air bubbles remaining in the buret tip or valve. Record the initial level – it does not need to

Zero out the triple beam balance. 2. Find the mass of the empty container. 3. Find the mass of the container with the liquid. 4. Subtract the container’s mass from the total mass to get the mass of the liquid. 5. Record the measurement in g. Measuring Out a Substance-powders 1. Zero out the triple beam balance 2. Find the

IT impact on productivity and business performance continues to be questioned. The paper critically reviews this IT productivity paradox debate and finds that an important part of the uncertainty about the IT payoff relates to weaknesses in measurement and evaluation practice. The approach shows how to link business and IT/IS strategies with prioritizing IT investments and by setting up interlinked measures‚ how IT costs and benefits may be evaluated and managed across the systems lifecycle

conducted to aid in understanding the formula for the circumference of the circle. Use a piece of string to measure the distance around a circular object. Measure the diameter and then divide the circumference by the diameter. The result of this measurement is an approximation for the number π‚(pi). (John Murray‚ 1989 ) π = Circumference = C Diameter D An alternate version of this formula is

then connect 2 conducting wires to the circuit board and put an ammeter in between the 2 conducting wires and read the measurements‚ after reading the measurements record it. Do the same thing as above but add 1 more conducting wire in between 1 conducting wire and the ammeter and connect that conducting wire to the first conducting wire with an alligator clip and read the measurements then record it.

Objectives The main objective of this experiment was to determine the spring constant using the dynamic method. 2. Theoretical fundamentals On the one hand‚ when a spring oscillates‚ the movement which describes can be classify as a simple harmonic motion. Therefore‚ its position‚ velocity and acceleration equations respect the time will

Our sources of error could have included eye measurement error‚ timing of set solutions error‚ measurement errors‚ and small calculation errors. Among other variables‚ the calibration of the analytical balance and spectrophotometer could have been off slightly‚ yet our results‚ like most other groups‚ still followed the general trend line generated by the graph using Beer’s Law. The measurement errors could have occurred due to the fact

of water flowing (dependent variable) changes in response--you observe that the water flow increases. The number of dependent variables in an experiment varies‚ but there is often more than one. Levels of Measurement The level of measurement refers to the relationship among the values that are assigned to the attributes for a variable. What does that mean? Begin with the idea of the variable‚ in this example "party affiliation." That variable has
