I believe it is A. Electrons reside in known positions in fixed orbits around the nucleus
Changing the medium of the wave.
Waves is always determined by the properties of the medium, which means that changing the medium will change the velocity of the wave
Answer:
72 m
Explanation:
Given:
v₀ = 0 m/s
v = 60 m/s
a = 25 m/s²
Find: Δx
v² = v₀² + 2aΔx
(60 m/s)² = (0 m/s)² + 2 (25 m/s²) Δx
Δx = 72 m
The pitch of the sound is perceived to be lower when an object is approaching you while making a sound.
<h3>What is sound?</h3>
Sound is a type of vibration capable of propagating in a suitable media (e.g., air or water).
The sound waves are called acoustic waves and they have a well-defined frequency and amplitude.
In conclusion, the pitch of the sound is perceived to be lower when an object is approaching you while making a sound.
