Answer:
the fundamental frequency produced by the open pipe is 120.78 Hz
Explanation:
Given;
length of the open pipe, L = 1.42 m
speed of sound in air, v = 343 m/s
The length of the open pipe for the fundamental frequency is equivalent to half of wavelength;

The fundamental frequency produced by the open pipe is calculated as;

Therefore, the fundamental frequency produced by the open pipe is 120.78 Hz
<span>The wavelength of a proton traveling at a speed of 6.21 km/s is
wavelength = (6.63E-34 Js) / (1.67Eâ’27kg x 6.21E3m/s)
= 6.393E-9 m
Region of the spectrum for electromagnetic radiation of this wavelength will be Xrays.</span>
Answer:
210 m
Explanation:
Given:
a = -6.8 m/s²
v₀ = 54 m/s
v = 0 m/s
Find: Δx
v² = v₀² + 2aΔx
(0 m/s)² = (54 m/s)² + 2 (-6.8 m/s²) Δx
Δx ≈ 210 m
