Answer:
92.33Hz
Explanation:
A tuba is considered as having one open end and the other end is closed. Then:
f_n = n×v / 4L
so here
Where n = 4
f_4 = 116.5 Hz
116.5 Hz = nv/4L
116.5 Hz = 4v/4L
4×v / 4L = v / L
116.5 Hz = v/L............1
Let's assume the speed of sound is 343 m/s. Then substituting 343 m/s for v in equation 1
116.5 Hz = v/L
116.5 Hz = 343 m/s/L
Making L the subject
116.5 Hz × L = 343 m/s
L = 343m/s / 116.5Hz
= 2.944 m
Add 0.721 m to the length, and
f_4 = 343m/s / (2.944+0.721)m
f_4 = 343m/s ÷ 3.715
= 92.328 Hz
Approximately = 92.33Hz
Hence the new frequency for the 4th harmonic is 92.33Hz
Arete is a sharp ridge separating two cirques or glacial vallies found in mountain regions. It is French for fishbone or the backbone of a fish, spine
Answer: Hand span
Explanation: Hand span is not a standard unit.
Second is the unit of time.
Meter is the unit of length or distance covered by an object.
Gram is the unit of weight of an object.
Hand span is not a standard unit. This is because the size of hand varies from person to person. Hence, the correct option is (c) "hand span".
A Headland,a Sea Cave,a Sea Arch, and a sea cut cliff.
Answer:
No, just because the electric field is zero at a particular point, it does not necessarily mean that the electric potential is zero at that point. ... At the midpoint between the charges, the electric field due to the charges is zero, but the electric potential due to the charges at that same point is non-zero.
