correct value for the known resistance‚ the galvanometer must read zero. Second‚ to relate the resistance to a specific length a micrometer is used in connection to a variable resistance box. Use six difference lengths on the micrometer‚ we chose intervals of 10‚ starting at 10 centimeters and ending at 60 centimeters. For the first set of data points‚ drag the micrometer tab to rest on 10 centimeters (have the same person press down on the wire for every data point using the same force because a

Step Five: As your looking at this contraction‚ wondering ‘Where do I even begin?’‚ this process is actually very simple once you understand its components. So‚ you have 4 basic parts. You have the caliper‚ two brake pads‚ a rotor‚ and of course‚ some bolts and clips to hold everything in its place. “What are these so-called basic parts?”‚ well I am glad you asked. I will give a

The following increments were used when adjusting the caliper on each body part: finger 0.01 inches‚ palm 0.05 inches‚ forearm 0.1 inches‚ back 0.1 inches. To accurately record the threshold for each body part manipulated‚ the following conversions were used for the dial caliper: 10 on the watch dial = 0.01 inches‚ 50 on the watch dial = 0.05 inches‚ 100 on

The reading on the built-in dial micrometer is recorded at room temperature‚ then‚ steam is passed around it. The expansion of the metal is measured using the dial micrometer. Fill the boiler about one-half full of water‚ cap it loosely‚ and connect the rubber hose to its spout. Heat with a Bunsen burner. First‚ measure the length‚ L‚ of the rod using a

SCIENCE PROCESS SKILLS Basic Science Process Skills: 1. Observing - using your senses to gather information about an object or event. It is description of what was actually perceived. This information is considered qualitative data. 2. Measuring - using standard measures or estimations to describe specific dimensions of an object or event. This information is considered quantitative data. 3. Inferring - formulating assumptions or possible explanations based upon observations. 4

total amount of aerosols in our atmosphere. Particle pollution includes "inhalable coarse particles‚" with diameters larger than 2.5 micrometers and smaller than 10 micrometers and "fine particles‚" with diameters that are 2.5 micrometers and smaller. How small is 2.5 micrometers? Think about a single hair from your head. The average human hair is about 70 micrometers in diameter – making it 30 times larger than the largest fine particle.
