Question

question 17: if 1 inch equals 2.54 centimeters, then how many centimeters are in 10 inches? a. 25.4 cm b. 2.54 cm c. 254 cm d. 0.254 cm question 18: dimensional analysis can be used to check if an equation is: a. dimensionally consistent b. thermodynamically stable c. chemically reactive d physically unstable question 19: converting 1000 grams to kilograms yields.

Explanation:

Step1: Identify conversion factor

We know 1 inch = 2.54 cm.

Step2: Calculate for 10 inches

Multiply 10 by 2.54, so $10\times2.54 = 25.4$ cm.

Dimensional analysis is used to check if the dimensions on both sides of an equation match, i.e., if the equation is dimensionally consistent.

We know that 1 kilogram = 1000 grams. So when converting 1000 grams to kilograms, we divide by 1000. $1000\div1000=1$ kg.

Answer:

A. 25.4 cm
