The size of spherical aerobic bacteria is limited by the rate at which oxygen diffuses through water. a bacterium with a radius greater than roughly 10 μm is not able to obtain enough oxygen from the surrounding water to sustain itself. given that the diffusion constant of oxygen in water is 8 ×10−10 m2s-1, how long does it take oxygen in water to diffuse an rms distance of 10 μm?

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n → ∞ n (9.8)(45−3 xi) i = 1 δx express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
