when testing for current in a cable with eleven colored-coded wires, the author used a meter to test five wires at a time. how many different tests are required for every possible pairing of five wires?
These are a list of the main tools you will need: Water samplers; bottom samples; messengers; animal/plant samplers; dissecting microscope; telescope; compound microscope; satellite; electron miscroscope; thermometer; oxygen probe; chemical test kit; visibility and color; sounder (lead line); fathometer; surveying equipment; hydrometer set; chemical test (Knudsen); salinometer; pHchemical test kit; pH meter; current meter; dye; drogues; drift bottles and drift cards.
there are a number of commercially avilable products that test the purity of gold (the Carat) from that you can extrapalate the percentage. 9 carat = 37.5% on the otherhand if it's recenlty made in a developed country it will be marked. (9ct or 9k)
Rules can vary from jurisdiction to jurisdiction, but typically, only your utility company can move the meter. To relocate a meter- -contact your Building Department and obtain a building permit for the plumbing change -contact your natural gas utility company to coordinate the move -contact the local "Dig Alert" service for your area, before trenching for the new gas line or any other excavation where there might be buried utilities. See this sight to find your local service- http://www.call811.com/state-specific.aspx -replumb your house-side gas line to the new meter location (in most jurisdictions, this must be done by a licensed plumber) -pressure-test the new house-side gas line -trench from the existing meter to the new location, per the requirements provided by your utility company -get the new house-side plumbing and trenching inspected by your building inspector -once you've passed inspection, schedule the meter move with your utility company. They will do the actual meter move (typically for a fee), and connect the meter to your new stub-out.

The purity of copper refers to the amount of copper content in a sample, typically measured as a percentage. The higher the purity, the less impurities present in the copper sample, making it more valuable for certain applications such as electrical wiring or conductors. High-purity copper is often used in industries where conductivity and corrosion resistance are critical requirements.
One way to test if a bracelet is made of pure copper is to use a magnet; copper is not magnetic, so if the bracelet is attracted to the magnet, it likely contains other metals. You can also try conducting a vinegar test by applying a few drops of vinegar to a hidden area of the bracelet and observing if it causes any discoloration, as pure copper will not react to vinegar. Additionally, look for any marks or stamps indicating the copper purity level on the bracelet.

Purity tests are used to determine the extent to which a particular substance is what is claimed. A classic purity test for gold is nitric acid; if the item being examined reacts to the acid it is not gold, or at least not pure gold.
Ephedrine can show a false positive for amphetamines on a drug test.
This is possible by chemical analysis.

Your answer depends on the purpose of your test.
