lens is 10cm.
a) Draw a diagram (scale 1/

a diagram (scale 1/2) showing the
al center O and the foci F and F of
Two
rays
falling on
b) Given:
the lens.
the
converging lens come out of a very far
point A on the optical axis so that these
rays are parallel to each other and
parallel to the optical axis. Construct the
path of these rays through the lens and
deduce the position of the image A of A'
given by the lens.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.  

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
