Students collect information on objects which change position due to a push or a pull. What is eh best unit of measurement to use when recording an object's change of position.

Meters

Step-by-step explanation:

The position of an object is its location at a given time. Which is subjected to change with respect to time, especially for any object which has potential energy.

In the standard unit of measurements (SI unit), it is required that distance which is a measure of length is recorded in meters. Thus, the best unit of measurement to use when recording a change in the position of an object is meters.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

answer: 1 and 3
