You're an electrical engineer designing an alternator (the generator that charges a car's battery). Mechanical engineers specify a 10-cm -diameter rotating coil, and you determine that you can fit 250 turns in this coil. To charge a 12-V battery, you need a peak output of 14 V when the alternator is rotating at 2000 rpm. Part A What do you specify for the alternator's magnetic field? Express your answer to two significant figures and include the appropriate units. B =

You're an electrical engineer designing an alternate the generator that changes a car's battery). Mechanical engineers specify a 10 cm diameter rotating cod, and you determine that you can ft 250 turns in this coil. To charge a 12-V battery, you need a peak output of 16 V when the alternator is rotating at 1100 rpm. What do you specify for the alternator's magnetic field? Express your answer to two' significant figures and include the appropriate units.

Problem 2.64 Constants| Periodic Table Part A You're speeding at 86 km/h when you notice that you're only 11 m behind the car in front of you, which is moving at the legal speed limit of 60 km/h. You slam on your brakes, and your car negatively acceleratos at 4.0 m/s Assuming the other car continues at constant speed, will you collide? no yes Correct Part B What will be the distance between the cars at their closest approach?

Problem 22.28 M ReviewI Constants 1 Periodic Table Part A A rear window defroster consists of a long, flat wire bonded to the inside surface of the window. When current passes through the wire, it heats up and melts ice and snow on the window. For one window the wire has a total length of 12.2 m, a width of 1.6 mm, and a thickness of 0.11 mm. The wire is connected to the cars 12.0 V battery and draws...

Problem 9.65 ③ 50t 11 Review I Constants 1 Periodic Table Part A A typical raindrop is much more massive than a mosquito and falling much faster than a mosquito flies. How does a mosquito survive the impact? Recent research has found that the collision of a falling raindrop with a mosquito is a perfectly Inelastic collision. That is, the mosquito is "swept up by the raindrop and ends up traveling along with the raindrop. Once the relative speed between...

I Review Constants Periodic Table Part A What is the uncertainty of the position of the bacterium? A student is examining a bacterium under the microscope. The E. coli bacterial cell has a mass of m = 0.500 fg (where a femtogram, fg, is 10-15 g) and is swimming at a velocity of v = 1.00 um/s, with an uncertainty in the velocity of 9.00 % . E. coli bacterial cells are around 1 um (10-6 m) in length. The...
