) The volume of mercury thread in a capillary tube is 1cm 3 . if the length of the mercury thread is 1m, calculate the radius of the capillary tube.

0.56cm

Step-by-step explanation:

a capillary tube has a cylindrical shape. So we need the formula for the volume of a cylinder:

where is a constant,

is the radius of the cylinder (the capillary), and is the length  (in this case the length of the mercury thread )

since we need the radius, we solve for it in the last equation:

The information that we already know is:

so we substitue this values:

the radius of the capillary tube is 0.56cm

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.
