Chapter 11, Problem 30A
You cannot stand with your heels and back to the wall and then lean over and touch your toes without toppling. Would either stronger legs or longer feet help you to do this? Defend your answer.
Expert Solution & Answer
To determine
To identify: Weather stronger legs or longer feet will help a person to stand with heels and back to the wall and then lean over and touch toes without toppling.
Answer to Problem 30A
Longer feet.
Explanation of Solution
Introduction:
Center of gravity helps in maintaining the position weather standing straight still or leaning forward.
Longer feet provide a bigger base and stable center of gravity. Hence, while leaning forward stability can be maintained for a longer time without toppling.
However, using normal feet but stronger legs center of gravity will be disturbed and there are possible chances of toppling while leaning forward in lesser time.
Conclusion:
Thus, longer feet will help to maintain the position and center of gravity while leaning over.

- Passage Problems Laptop computers are equipped with accelerometers that sense when the device is dropped and then put the hard drive into a protective mode. Your computer geek friend has written a program that reads the accel- erometer and calculates the laptop's apparent weight. You're amusing yourself with this program on a long plane flight. Your laptop weighs just 5 pounds, and for a long time that's what the program reports. But then the "Fasten Seatbelt" light comes on as the plane encounters turbu- lence. Figure 4.27 shows the readings for the laptop's apparent weight over a 12-second interval that includes the start of the turbulence. 76. At the first sign of turbulence, the plane's acceleration a. is upward. b. is downward. c. is impossible to tell from the graph. 77.

You estimate that a transmission wire is about 12 m above the ground. The local power company tells you that the line operates at 12 kV and provide a maximum of 60 MW to the local area. Estimate the maximum magnetic field you might experience walking under such a power line, and compare to the Earth's field.
