transcontinental plane flight, your coffee cup sits motionless on your tray. Are there forces acting on the cup? If so, how do they differ from the forces that would be acting on the cup if it sat on your kitchen table at home? Determine the Concept Yes, there are forces acting on it. They are the normal force of the table and the gravitational pull of Earth (weight). Because the cup is not accelerating relative to the ground, the forces are the same as those that would act on it if it was sitting on your table at home. 2 • You are passing another car on a r highway and determine that, relative to you, the car you pass has an acceleration a to the west. However, the driver of the other car is maintaining a constant speed and direction relative to the road. Is the reference frame of your car an inertial one? If not, in which direction (east or west) is your car accelerating relative to the other car? Determine the Concept No. You are in a non-inertial frame that is accelerating to the east, opposite the other car’s apparent acceleration. 3 • [SSM] You are riding in a limousine that has opaque windows that do not allow you to see outside. The car is on a flat horizontal plane, so the car can accelerate by speeding up, slowing down, or turning. Equipped with just a small heavy object on the end of a string, how can you use it to determine if the limousine is changing either speed or direction? Can you determine the limousine’s velocity? Determine the Concept In the limo…

thoroughly that I came back restless. Instead of being the warm center of the world the middle-west now seemed like t he ragged edge of the universe—so I decided to go east and learn the bond business. Everybody I knew was in the bond business so I supposed it could support one more single man. All my aunts and uncles talked it over as if they were choosing a prep-school for me and finally said, ‘Why—yees’ with very grave, hesitant faces. Father agreed to finance me for a year and…

direct drive for both the slow oscillating wash cycle and the fast spin cycle. Variable reluctance motors do have a drawback. With sinusoidal exciting currents, permanent magnet and hybrid motors are very quiet. In contrast, variable reluctance motors are generally noisy, no matter what drive waveform is used. As a result, permanent magnet or hybrid motors are generally preferred where noise or vibration are issues. Unlike variable reluctance motors, permanent magnet and hybrid motors…

underestimate) will total 104 pizzas, as will a school of 250 students averaging 40 pizzas a year each. 1.28: The moon is about 4 × 108 m = 4 × 1011 mm away. Depending on age, dollar bills can be stacked with about 2-3 per millimeter, so the number of bills in a stack to the moon would be about 1012. The value of these bills would be $1 trillion (1 terabuck). 1.29: (9,372,571 km 14 (Area of USA ) (Area bill ) = number of bills. 2 × 106 m 2 km 2 15.6 cm × 6.7 cm × 1 m 2…

what mental game he brings along. -- As motivated as Hansen should be to win X Games, he's yet to prove in 2013 that he's serious about this. In Foz he uncrated his bike and found that the lower steering stem nut was missing off his Suzuki RM-Z 450. He robbed the one off of Jolene Van Vugt's Enduro X bike but still missed practice. In the final, he showed his talent but instead of concentrating on his next run he spent all of his prep time sticking his face in front of the cameras and…
