Return to Required information Sometimes equations can be developed and practical problems solved by knowing nothing more than the dimensions of the key parameters. For example, consider the heat loss through a window in a building. Window efficiency is rated in terms of R value, which has the unit of ft2-hr-F/Btu. A certain manufacturer offers a double-pane window with R=2.5 and also a triple-pane window with R=3.4. Both windows are 3.5 ft by 5 ft. On a given winter day, the temperature difference between the inside and outside is 45°F. Assume that a homeowner buys 20 such triple-pane windows for the house. A typical winter equals about 120 heating days at AT = 45°F. Each triple-pane window costs $85 more than a double-pane window. Ignoring interest and inflation, how many years will it take the homeowner to make up the additional cost of the triple-pane windows from heating bill savings? 9.5 years S MacBook Air !

Fv = 390 N Sur Previous Answers Mountaineers often use a rope to lower themselves down the face of a cliff (this is called rappelling). They do this with their body nearly horizontal and their feet pushing against the cliff (Eigure 1). Suppose that an 78.6-kg climber, who is 1.88 m tall and has a center of gravity 1.0 m from his feet, rappels down a vertical cliff with his body raised 40.4° above the horizontal. He holds the rope 1.54 m from his feet, and it makes a 20.7° angle with the cliff face. ✓ Correct Part D Figure 1 of 1 What minimum coefficient of static friction is needed to prevent the climber's feet from slipping on the cliff face if he has one foot at a time against the cliff?
