question 11 ed
how does a laser measuring device improve precision?
a. by using a tape for manual measurement
b. by estimating distances visually
c. by using a ruler for quick measurements
d. by using a laser beam for accurate distance measurement
select an answer

Explanation:

To measure distance accurately for precise work (like in engineering, physics experiments, or technical tasks), a laser beam is used for its high precision. Tapes (A) have human error in manual use, visual estimation (B) is very inaccurate, and a ruler (C) is less accurate than a laser for precise distance measurement. So the best method for accurate distance measurement is using a laser beam.

Answer:

D. By using a laser beam for accurate distance measurement
