Lab 1: the metric system – measurement of length and weight introduction the scientific community and the majority of nations throughout the world use the metric. • to obtain measurements of length, mass, volume, and temperature • to determine the mass and volume of an unknown rectangular solid • to gain proficiency in using the following instruments: metric rulers, balances, graduated cylinder, and thermometer the metric system uses a basic set of. View lab report - lab 1 measurment in chemistry (2) from chem 105 at taylor's university lab 1: measurements in chemistry introduction most chemistry lab activities involve the use of various. Lab #1: gsm transceiver measurements 1 introduction in this laboratory work properties of gsm mobile stations (ms) are investigated the goal is to learn.

Metric measurements and density lab introduction the metric system (si – french for “systeme international d’ unites”) is the standard system of measurement in the scientific world during this laboratory exercise you make various measurements of mass, volume, and temperature these measurements will also be used to determine. Lab activity: measuring with metric 3 heed these rules: 1 you should always use decimals (never fractions) to express metric measurements for example: write 225 cm, not 2 ¼ cm 2 if a metric measurement is less. The idea is that a de of 10 is the smallest color difference the human eye can see so any de less than 10 is imperceptible (as in turn the lights off and head to the pub) and it stands to reason that any de greater than 10 is noticeable (as in put the coffee on, we're going to be here a while) unfortunately - and probably not surprisingly.

Fig10 sound-lab a-1, anechoic response at 45 with microphone 36 from floor, averaged across 30° horizontal window and corrected for microphone response, with nearfield response (average of 6 spaced measurements) plotted below 200hz (brilliance control set to maximum. L01-2 lab 1 - physical measurements university of virginia physics department phys 1429, spring 2011 the “true” value that we seek. 12 uncertainties in measurements in lab in the laboratory you will be taking real world measurements, and for some measurements you will record both measured values and uncertainties getting values from measuring. See lab 0) step 6: using the dmm, measure the resistance of the light bulb does this correspond to the value you would expect from ohm's law given the values of voltage and current you measured in parts 1 and 2. Psych 360: physiology of behavior january 23, 2006 lab #1: physiological measurements the goal of today’s lab is to fiddle around with.

Lab report 1 – laboratory techniques and measurements brittany hilbun online chem no credit will be given for this lab report if the data section is not c. Experiment 1: measurement and precision experiment 1: measurement and precision objective: to determine the value of from the ratio of the circumference to the diameter of a circle (actually, the real point of this lab is to introduce you to the concept of uncertainty in measurements) theory: it has been known since ancient. Note: for the airfoil surface pressure distribution measurements, it is recommended to run the dsa 3217 unit with the data acquisition of 300 ~ 400hz for about 20 seconds in order to calculate the averaged pressure for each pressure tap. Activity 134 measurement lab – skimmer introduction throughout history many systems of measurement have been devised and then thrown out as more precise and more logical systems have come along while most of the world has adopted the metric system, the united states still clings to the standard system, also called the. Measurements will be within 1σ of the mean, and 95% within 2σ therefore, when we use a single measurement as a guess for the mean value, the uncertainty of that guess is just σ, the standard deviation.

(141 – 143) = (-02)2 / (11-1) σ = sqrt(000004) = 006 = 01 this measurement is fully acceptable and within 1 of the mean (68% of all expected measurements) 7 what about a measurement of 136 sec for a measurement of 136, there is difference of 07 seconds from the mean if we square this value we get 0049 we then divide by (11-1. School of electrical engineering and telecommunication elec3106 electronics lab 1: op-amp measurements objective the objective of this laboratory session is to give the students a good understanding of critical. The distribution from figure 1 has three different values for the mean, median, and mode the mode is the easiest the mode is the easiest to ﬁnd: it's the location of the peak, which is at x=2 to ﬁnd the median, we have to ﬁnd the point which divides the. 1 | p a g e me ure ent: uncertainty and error in lab measurements measurement is at the heart of science in order to do science, we must.

The vernier caliper (figure 1) is a fairly simple measurement tool it has two parts: it has two parts: a stem with the main scale (cm, mm. Lab group 77 page 3 of 3 conclusions our period vs mass measurements showed almost no noticeable variation with mass theory predicts no variation at all. System internationale / the metric system most people known as the metric system even england, where our english system originated, uses si, and our own us official measurements are defined using si units why is si so popular one major reason is that, once you learn a basic unit, larger and smaller versions always follow.

The least count of an instrument is the size of the smallest scale division on the instrument the smaller the least count the more precise the instrument is said to be for example a metric ruler which has millimeter marks has a least count of 1 mm or 01 cm and when properly used it can make more precise measurements than one with. Physics 100 lab – measurements, conversions, and equations pg 2/4 conversions scientists use the international system of measurement (si units) when making measurements.

1 measurements and instrumentation lab #1: introduction to electronic instrumentation equipment: dc power supply (lambda lp -411a-fm) digital multimeter (fluke 8050a) function generator (tektronix cfg250. Physics and measurement by a comparison of the results of accurate measurements with the numerical predictions of the theory, we can gain considerable confidence that the theory is correct, and we can determine in what respects it needs to be modified.
