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?

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy

An object with a mass of 1.5 kg changes its velocity from + 15 m/s to +22 m/s during a time interval of 3.5 seconds. what impulse was delivered to the objects?
