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.

The loop is oriented so that the plane of the loop is perpendicular to the plane of the page (this means that the normal vector for the loop is always in the plane of the page!). In the illustrations below the magnetic field is shown in red and the current through the current loop is shown in blue.
