Question

question 26: true or false: converting 60 minutes to hours yields 1 hour. a. true b. false question 27: true or false: dimensional analysis can also help identify errors in derived equations. a. true b. false question 28: true or false: a conversion factor for centimeters to meters is 0.01. a. true b. false

Explanation:

Step1: Recall time - unit conversion

We know that 1 hour = 60 minutes. So converting 60 minutes to hours gives 1 hour.

Step2: Understand dimensional - analysis use

Dimensional analysis checks if the dimensions on both sides of an equation are the same. If they are not, there is an error in the equation.

Step3: Recall length - unit conversion

1 meter = 100 centimeters. So to convert centimeters to meters, we divide by 100, and the conversion factor is 0.01.

Answer:

Question 26: a. True
Question 27: a. True
Question 28: a. True
