the ground. Leaves absorb carbon dioxide from the air to form carbohydrates that are used in the plant’s structure and function. In this process‚ leaves also absorb other air pollutants—such as ozone‚ carbon monoxide‚ and sulfur dioxide—and give off oxygen. By planting trees and shrubs‚ we return to a more natural‚ less artificial environment. Birds and other wildlife are attracted to the area. The natural cycles of plant growth‚

DESIGN SPECIFICATION Design Specification for a Portable Winch The following example PDS contains many aspects of a commercial PDS and was written with advice from a winch design company. A real design brief for a winch would contain many more aspects than outlined here. A PDS for family motor car for example‚ would have many more categories specific to the product and would require several large manuals to list the ’problem’ in detail.

A Portable Motorized Body Board The lightest personal watercraft on the market weighs 600 pounds. Jason Woods’s Kymera (named after both the mythological creature and a type of deepwater fish) weighs a mere 35. The concept was a carbon-fiber body board powered by a small engine that would propel a rider at exhilarating speeds while displacing roughly half an inch of water. Vacationers could explore waterways without a boat‚ and because the Kymera would weigh only 35 pounds‚ one person could haul

Analysis: The graph of oxygen uptake vs time taken to run 1.5 miles has a negative linear association. As oxygen uptake increases‚ the time taken to run 1.5 miles decreases. This is can be seen through the gradient which has a value of 0.1705. This means that as the oxygen uptake increases by 1 ml/kg the amount of time taken to run 1.5 miles tends to decrease by approximately 1.7 minutes. The graph has a moderate relationship because the data is scattered in a wide band along the line of best fit
