Beats are interference patterns between two tones of different frequencies. To prove the skeptic first, play the recorded audio as there are no beats in it. Now take two sound sources with different frequencies. When both sources are turned on, we hear notes that rise and fall at equal intervals. That's what's called beats.
A frequency beat occurs when two waves with different frequencies overlap, causing alternating cycles of constructive and destructive interference between the waves.
When we tap the table with our finger, then put our ear to the table, and tap the table surface as far as 30 cm from our ear. Then the sound of beats on the table will sound louder when we put our ears on the table. So, it can be concluded that solid objects can conduct sound better than air. This is because the molecules or particles of solid objects are denser than air.

Answer: 0.091 m
Explanation:
r = 1/B * √(2mV/e), where
r = radius of their circular path
B = magnitude of magnetic field = 1.29 T
m = mass of Uranium -238 ion = 238 * amu = 238 * 1.6*10^-27 kg
V = potential difference = 2.9 kV
e = charge of the Uranium -238 ion = 1.6*10^-19 C
r = 1/1.29 * √[(2 * 238 * 1.6*10^-27 * 2900) / 1.6*10^-19]
r = 1/1.29 * √(2.21*10^-21 / 1.6*10^-19)
r = 1/1.29 * √0.0138
r = 1/1.29 * 0.117
r = 0.091 m
Therefore, the radius of their circular path is 0.091 m
Answer:
The distance between the two successive crests of the wave is 360m
Explanation:
Wavelength is defined as the property of wave in which the distance between identical points between two successive waves are calculated
Wavelength is referred to as the <em>distance between two successive crests or troughs</em>
<em>Given that:</em>
speed = 72.0 m/s
time = 5 seconds
Using the formula
C = fλ
Where C = speed, f = freequency and λ = wavelength
F = 1 / time
F = 1/5
F = 0.2Hz
From the fomula C = fλ
make λ the subject of the formula
λ = C / f
λ = 72/0.2
<em>λ = 360m</em>
