The following are a list of requirements for the production of amobile phone that is required to communicate using either voice ortext.
1. The phone should use a nickel cadmiumbattery.
Exercise 1
Determine if these requirements meet the validation criteria. Ifnot explain why and rewrite the list of requirement so that theydo.
Exercise 2
Are all the types of requirements covered (environmental,performance, etc). If not, what areas need to be covered byadditional requirements to make the list of requirementscomplete.
Exercise 3
Write a test to assess compliance with the following requirement.Note you may have to rewrite the requirement first.
1. The phone should have a stand-by time of 500 hours.
2. The phone should operate at any geographic location within theUSA mainland.
Colette Lake has a surface area of 103 ha and a mean depth of 8 m. The pH of the water is 7.6. The lake receives surface water from a lake upstream, rainfall, and diffuse groundwater input. Atmospheric inorganic N deposition is insignificant.
a cylinder has 500 cm3 of water. after a mass of 100 grams of sand is poured into the cylinder and all air bubbles are removoed by a vacuum pump, the water level rises to 537.5 cm3. Dteremine the specific gravity on the sand
