Standing erect, a measurement was taken from the axillary to the longest finger tip of each subject 4. Standing erect, a measurement was taken of each subjects height minus shoes 5. #3 and #4 data was collected from each subject and logged 6. Height was multiplied by .4 to determine expected upper limb length and logged 7. Upper limb length was divided by height to give actual % of height and logged TABLE 1.1 Subject: | Measured Upper Limb Length (cm) | Height | Height x 0.4= Expected Upper | Actual % of Height = Upper Limb Length (cm) Height (cm) | Shane | 71.5 | 178.6 | 71.4 | 40% | Gena Lyn | 62.9 | 155.6 | 62.2 | 40.40% | Kayli | 76.4 | 163.9 | 65.5 | 46.60% | L.B.

Error Is 6.34% Lab Report: Part 1: In this lab we used the following supplies: * Zinc Iodide * Na2H2EDTA(s) * Calmagite indicator solution * pH 10 buffer solution * 6M Acetic Acid * Unknown Zinc Compound The main purpose for this part of the lab was to determine the amount of zinc ion in a sample of ZnI2 by titration.
The formula S = C (1 + r)^t models inflation, where C = the value today r = the annual inflation rate S = the inflated value t years from now Use this formula to solve the following problem: If the inflation rate is 3%, how much will a house now worth $510,000 be worth in 5 years? 510000(1ⓜ┤+ⓜ0.03)^5 =591229.777893 591229.77789300005 Write 6 = log2 64 in its equivalent exponential form. 26=64 Write 8y = 300 in its equivalent logarithmic form. log 300 = log 8y log(3*100)=log 8y log 3+log100=log 8+log y log 3+2=log 8+log y log 8-log 3=log y-2 By log(A/B)=log A-log B, log (8/3)=log y-2 Hurricanes are some of the largest storms on earth. They are very low pressure areas with diameters of over 500 miles.
Adam Workman Lab, Week #1 Balance Lab Introduction The purpose of the Balance Lab experiment was to become familiar with the ChemLab software and to become familiar with different mass measurement methods. During the experiment, three different mass measurement methods were used to determine the mass of copper slugs as well as the mass of two different unknown weights: the direct weight method, the weighing by difference method, and the average mass method using both a centigram balance and an electronic balance. Using the centigram balance, the weight of a single copper slug, in grams, is determined using both the direct weight and weight by difference methods. Likewise, using the electronic balance, the same copper slug is measured by direct weight and weighing by difference methods. Using the same electronic balance, the average mass of five copper slugs, in grams, will be determined.
Physics Lab Report Introduction - All People exert forces, but do we know how much force we exert? My hypothesis is that some people have already created a scale for themselves to determine the amount of force they exert and everyone has the ability to create this scale giving everyone the ability to estimate the amount of force they exert. I try to prove the first part my hypothesis by comparing two twins of about the same height and muscle mass' ability to sense the amount of force they are exerting on different objects. Then I get two people of very different muscle masses and heights to try and create a scale. My experiment works based on the idea that the force that people exert to keep mass suspended is equal to the weight force of the mass because of Newton’s Third Law (action reaction pairs).

When you give the fluids d) Where do you record this information? On the fluids chart e) Identify legislation related to handling information in a Health & Social Care Setting Data Protection Act 1998 4. Using the chart below work out: a) What is Frank’s weekly weight loss or gain? Fill in the chart below b) Now compare this with his start weight, how much has he lost altogether 1kg c) Frank would like to know what his weight is in stones and pounds. To change kilograms to pounds [multiply (x) 2.2] 1kg = 2.2 pounds To change pounds into stones [divide (:-) 14] 1 stone = 14 pounds Weight Record Clients: Frank K start weight 48.90 kg Date Weight (kg) Loss/gain 06/01/13 48.
However, that is an extra 2’ that require you to put away by hand after each use. This can lower productivity times for the housekeeping department. Warranty Both The Hoover and Kenmore vacuums offer a 2 year warranty on their vacuums. The Dyson offers a 5 year warranty which will have a direct impact on the final review. This gives the resort an additional 3 years to ensure all parts are functional.
Lastly we will explore standing waves and how string oscillations become affected by the string mass density. Theory As stated in order above, our first experiment of simple harmonic motion using an oscillating spring setup. By using a mass hanger attached to a rotary motion sensor, we are able to produce graphs and data to attempt to show the proofs for the theories and equations listed in the theory and graph section of the lab. The experiment started with adding 200g and progressively moved up to 350g for five trials. We then collected the data and analyzed the sine graph and the different portions of it and what they meant including the parameters and taking proper data.
