Q15E - University Physics with Modern Physics

Question

A useful and easy-to-remember approximate value for the number of seconds in a year is π x ${10}^7$. Determine the percent error in this approximate value. (There are $365.24$ days in one year.)

Step-by-Step Solution

Answer

If we plug the number into equation where we have to subtract the experimental from the actual ,you should get the right answer.

Definition

It  is difference between actual value and estimated value in the comparative manner with actual value as percentage

Mathematical expression for percentage error

For calculating percentage error simply divide of experimental value

 (${10}^7$)by the actual value ($3.{155673610}^7$),but it is close

Conclusion

$\frac{actual-experimental}{actual}\times 100$

So, if we plug the number into equation where we have to subtract the experimental from the actual ,you should get the right answer.
