Q & A

  • What is the main goal of the tutorial?

    -The main goal of the tutorial is to convert 55 miles per hour to nanometers per second.

  • How many steps are involved in the conversion process?

    -The conversion process is broken down into two main steps: converting miles to nanometers and converting hours to seconds.

  • What is the first conversion factor used in the tutorial?

    -The first conversion factor used is to convert miles to meters, specifically 1 mile equals 1,609.34 meters.

  • How are the units aligned during the conversion?

    -Units are aligned to cancel each other out. For example, miles are aligned across from miles, allowing them to cancel out in the first step.

  • What is the second conversion factor used for converting meters?

    -The second conversion factor used is to convert meters to nanometers, where 1 meter equals 1,000,000,000 nanometers.

  • What is the purpose of rounding the final answer?

    -Rounding the final answer is important to reflect the significant figures of the initial measurement, which in this case is two significant figures.

  • How do you convert hours to seconds in the second step?

    -To convert hours to seconds, first convert hours to minutes (1 hour = 60 minutes), and then convert minutes to seconds (1 minute = 60 seconds).

  • What is the formula for converting nanometers per hour to nanometers per second?

    -The formula is: Value in nanometers per hour divided by (60 minutes × 60 seconds).

  • What motivational advice does the tutor provide at the end of the tutorial?

    -The tutor encourages students to practice as much as possible and assures them that determination is key to success in exams.

  • Why is it beneficial to break down the conversion into smaller steps?

    -Breaking down the conversion into smaller steps makes the process more manageable and helps prevent mistakes, ensuring a clearer understanding of each part of the conversion.
