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. The plane's vertical ac-
celeration has its greatest
magnitude
a. during interval B.
b. during interval C.
c. during interval D.
78. During interval C, you can
conclude for certain that the

If the metal sphere on the Van de Graff has a charge of 0.14 Coulombs and the person has a mass of 62 kg, how much excess charge would the person need in order to levitate at a distance 25 cm from the center of the charged metal sphere? Assume you can treat both the person and the metal sphere as point charges a distance 25 cm from each other
If the metal sphere on the Van de Graff has a charge of 0.14 Coulombs and the person has a mass of 62 kg, how much excess charge would the person need in order to levitate at a distance 25 cm from the center of the charged metal sphere? Assume you can treat both the person and the metal sphere as point charges a distance 25 cm from each other (so that you can use Coulomb's Law to calculate the electrical force).

- Using Coulomb's Law, calculate the magnitude of the electrical force between two protons located 1 meter apart from each other. (Give your answer as the number of Newtons but as usual you only need to include the number, not the unit label.)arrow_forwardPart A You want to get an idea of the magnitude of magnetic fields produced by overhead power lines. 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.
