Find the terminal velocity of a spherical bacterium (diameter ) falling in water. You will first need to note that the drag force is equal to the weight at terminal velocity. Take the density of the bacterium to be

The value is

Explanation:

From the question we are told that

   The diameter of the  spherical bacterium is

     The density of the bacterium is  

Generally the radius is mathematically represented as

=>  

=>  

Generally the volume is mathematically represented as

=>

=>

Generally the mass is mathematically represented as

=>  

=>  

Generally the terminal velocity is mathematically represented as

Here   is the viscosity of water with value  

So

=>
