Final answer:

The frequency that might be heard from the copper pipe open at both ends is approximately 367.8 Hz.

Step-by-step explanation:

The fundamental frequency of a pipe open at both ends can be calculated using the formula:

f = (nv)/(2L)

Where:
n is the mode of the sound wave (1, 2, 3, ...)
v is the speed of sound in air
L is the length of the pipe

In this case, the length of the copper pipe is 45.0 cm, which is equal to 0.45 m. We have to assume the speed of sound in air, which is approximately 331 m/s at room temperature. Let's calculate the fundamental frequency:

f = (1 x 331)/(2 x 0.45) = 367.8 Hz

Therefore, the frequency that might be heard in this case is approximately 367.8 Hz.
