Explain why the “invisible man” would be unable to see.

Answer to Problem 1CQ
Explanation of Solution
An “invisible man” is unable to see because he allows the light to pass through uninterruptedly just like a light passes through thin air. If some of the incident light is deflected or absorbed, then the person will see the effect and the person will no longer stays invisible. The person would be visible only if some incident light is absorbed by the retina. This creates a hindrance in the path of light and thus the invisible man seems visible.
Conclusion:
Therefore, the “invisible man” would be unable to see because he allows the light to pass through uninterruptedly and no light is absorbed by the retina.

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.
