Speed equals distance divided by time (Speed=Distance/Time).
For example if it takes someone three minutes to go three miles their speed is one mile a minute.
Changing frequency of sound does not change the speed of the sound.
Explanation:
- Speed of the sound gets altered when the sound travels from one medium to another.
- Change in frequency does not affect the speed of the sound and speed is affected by the properties of the medium through which it travels.
- Therefore, to change the speed of the sound, the properties of the medium needs to be changed.
Answer:
I = 9.82 10⁻⁷ W / m²
Explanation:
The intensity of the sound wave is the energy of the wave between the order per unit area of the same
I = P / A = E / T A
the energy is calculated by integrating the mechanical energy in a period, where the mass is changed by the density and ‘s’ is the amplitude of the sound wave
I = ½ ρ v (w s)²
I = ½ 1.35 328 (2π 530 2.00 10⁻⁸)²
I = 221.4 (4.435 10⁻⁹)
I = 9.82 10⁻⁷ W / m²
Answer:
0.0170m or 1.70cm
Explanation:
L=(μ₀*N^2*A)/(l)
N=x/2*pi*r so r=x/2*pi*N
A=pi*r^2=(pi*x^2)/(4*pi^2*N^2)
L=(μ₀*N^2*A)/(l)=(μ₀*N^2*pi*x^2)/(4*pi^2*N^2*l)=(μ₀*x^2)/(4*pi*l)
l=(μ₀*x^2)/4*pi*L)=[(4*10^-7)*(1.15m)/4*pi*2.47*10^-6H)=0.0170m or 1.70cm
Hope this helps. Any questions please feel free to ask. Thanks!
