Help meh, no links and please give the right answer. What properties of an object would you observe when you use a metric ruler?

The first (or smallest measurement) you would see is the hash

marking millimeters, which is written as "mm". 1mm equals the

thickness of a dime. The unit of measure that is most often

displayed on a metric ruler would be centimeters written "cm". 10mm

equals 1cm and 2.5cm is about equal to 1 inch. Centimeters are

displayed for viewing like inches are, marked on the ruler in

increments of 1, 2, 3, 4... and so on. Usually to 30cm which is

slightly less than 12 inches

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
