Find the marks that line up exactly (or as exactly as possible and then interpolate). see the Sources and related links below for a page and a video explaining in detail.
if the zero line of vernier scale is not conciding with main scale the zero error exists.Knowing the zero error necessary correction can be made to find correct measurement..Such a correction is called zero correction
The first step is to find the zero error and hence the zero correction. Rotate the micrometer until the fixed and movable jaws contact each other - not too hard and not too soft but just right, you should geta feel for this. Rarely will a micrometer will read zero. You need to figure out the zero error. It may be positive or negative. If the zero error is positive then the zero correction is negative and vicevers. Now open the micrometer and insert the object to be measured and close the micrometer with ideally the same sense of pressure you felt when you found the zero error. Now read the micrometer. You add the zero correction to get the true value.
Outer jaws are used. Inner jaws will be use to find the inner dia of the cylindrical vessel.
If you have a caliper this is really easy. Corks are truncated cones. Measure the diameter of the cork at the top and at the bottom, average them, then calculate the volume using the average diameter.

They are not. You use the most suitable instrument for the task in hand. Some people find verniers more difficult to read unless there is a digital readout.

0.1 mm
by dividing diameter by 2 :)
Are you talking about the 2008 TV series Sense Sensibility?, because the movie was made in 1981.
On some vehicles there is a caliper mounting bracket, on others the caliper screws directly to the steering knuckle.

Disengage the parking brake before attempting to remove the caliper.

The cost of a Mitutoyo Micrometer in the 227-111 series varies, but is in the hundreds of dollars range. You can find this item used, however, for as little as $100.
A micrometer is the unit of measurement to find the diameter of the lung alveoli.
