## miah 2 years ago In the following equation T=2π√L/32 l stands for the length of the string in feet. Convert your 5 string lengths into feet by dividing by 12 (12 inches = 1 foot). Then, substitute each of these values into the given equation and solve for T (time for one period). Use 3.14 for π. 8 sec 6 sec 5 sec 6 sec 7 sec

What 5 string lengths? I only see time measurements?

3. miah

(1 1/2 ft) (1 ft) (2 ft) (1ft) (3ft)

4. miah

???

5. Mertsj

So you have already converted them to feet correctly, I will assume.

7. Mertsj

Do I have the formula right?

8. Mertsj

Is it: $T=\frac{2\pi \sqrt{L}}{32}or 2\pi \sqrt{\frac{L}{32}}$

9. miah

the 2nd one

10. miah

the second one is right

11. Mertsj

12. miah

uhm,. i guess

13. Mertsj

You can actually take $\frac{2\pi}{\sqrt{32}}=\frac{6.28}{5.66}=1.11$

14. Mertsj

and multiply each of your string lengths by that constant to get the time

15. miah

so what would the second one be ?

16. Mertsj

What did you get?
