Equipment Calibration is defined as the act of adjusting and evaluating the precision and accuracy of measured equipment. It allows the user to get an accurate and precise reading of measurements to its actual true value. However‚ in order for the experiment to be effective is must consist of validity‚ reliability‚ and objectivity. Validity is defined as the ability of a test to measure what it claims to measure. Reliability is the consistency of test results and objectivity is defined as a test

Unmanned Combat Air Vehicles (UAVs)‚ most commonly referred to as drones‚ are becoming a helpful asset to the military. Drones will most likely be relied upon more in the battlefield and save many military personnel lives because they can be controlled from states away‚ are becoming more persistent and technologically advanced‚ and are being equipped with highly accurate yet extremely dangerous weapons. First‚ according to (Sherman 35) the fact that a drone can be controlled from just outside of

Significant Figures are very important when reporting scientific data because they give us knowledge of how well we can actually measure data. Before getting into the calculations we must first understand the rules for counting significant figures. 1. All nonzero digits are significant. Example: 547 (3 sig. figs.) 2. Zeros in a number between non-zero digits are always significant. Example: 4308 (4 sig. figs.) 3. Trailing zeros to the right of a decimal point are significant. Example:

Walk This Way Project By: Leslie Dett Algebra 2 Project February 1‚ 2013 This project Walk this Way was actually a really good experiment. It wasn’t that hard nor that simple. You still had to apply everything you learned in math and be accurate with the numbers. Starting with the measurements of your leg to the time amount of time you walk in. Your accuracy had to be at a minimum range of numbers. Answering question number 8 in the worksheet I believe in some of them the
