Question #f15bd

Answer 1

To avoid serious errors.

Explanation:

A probe to Mars failed in 1999 because the team of designers failed to clearly indicate the units with a table of data. One group assumed impulse data from another group would be in `"Newton"*"sec" but it was in`pound"*"sec"#. Consequently, the impulse was wrong and the probe crashed.

Suppose you were sent to the market to get 12 of milk. Would you get 12 cc or 12 liters?

I hope this helps,
