Given data
*The given 4th harmonic frequency is 31.5 Hz
The fundamental frequency is calculated as
Hence, the fundamental frequency is 7.875 Hz
ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are measurements.

Answer:
3.8 x 10¹⁷ in
Explanation:
Light speed= 982,080,000 ft/s
year(time)= 32,000,000 seconds
converting ft/s to in/s for the speed of light:
1ft/s = 12 in/s
982,080,000 ft/s x 12in/s = 11,784,960,000 in/s ( speed of light in inches)
using the standard formula for speed:
V=
Distance( inches)= V (speed in/s) x Time (seconds)
Distance = 11,784,960,000 x 32,000,000
Distance≅ 3.8 x 10¹⁷ in
