Approximately 0.1 % of the bacteria in an adult human's intestines are escherichia coli. these bacteria have been observed to move with speeds up to 15 μm/s and maximum accelerations of 166 μm/ s 2 . suppose an e. coli bacterium in your intestines starts at rest and accelerates at 157 μm/ s 2 . you may want to review (pages 40 - 43) . part a how much time is required for the bacterium to reach a speed of 12 μm/s ?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

How would a small bar magnet be oriented when placed at position x?

What would be the strength of earth's gravitational field at a point where an 80.0 kg astronaut would experience a 80% reduction in weight
