Here are the essential concepts you must grasp in order to answer the question correctly.
Percent Error
Percent error is a measure of how inaccurate a measurement is, compared to the true value. It is calculated by taking the absolute difference between the approximate value and the true value, dividing it by the true value, and then multiplying by 100 to express it as a percentage. This concept is essential for evaluating the accuracy of approximations in scientific calculations.

Conversion of Time Units
Understanding how to convert between different time units is crucial for solving this problem. In this case, we need to convert days into seconds to find the true number of seconds in a year. Knowing that there are 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute allows us to perform this conversion accurately.

Approximation in Physics
Approximation is a common practice in physics to simplify complex calculations or to provide easy-to-remember values. In this question, π × 10^7 is used as an approximate value for the number of seconds in a year. Understanding the role of approximations helps in assessing their usefulness and limitations in practical applications.
