Answer

Question 3

Brief Explanations:

In dimensional analysis, units can be canceled when they are identical and appear in both the numerator and denominator of a fraction, similar to how numbers are canceled in algebraic fractions.

Answer:

When they appear in both the numerator and denominator

Question 4

Brief Explanations:

Converting miles per hour to meters per second requires conversion of distance (miles to meters) and time (hours to seconds), involving multiple conversion factors. Hours to minutes, pounds to ounces, and meters to kilometers are single - step conversions within the same physical quantity (time, mass, length respectively).

Answer:

miles per hour to meters per second
