Answer:
Wavelength of sound in meters = 1.348 m
Explanation:
Given
speed of sound = 34500 cm = 345 m
(since 1 cm = 0.01m)
frequency of sound = 256 Hz = 256
Wavelength of sound in meters = ?
We know that all waves have same relationship among speed s, frequency f and wavelength λ, which is given by the equation
v = fλ
Wavelength λ = v/f
= 345 m / 256
=1.348 m
Hence wavelength of sound in meters = 1.348 m
Answer:
Volume.
Explanation:
Boyle’s law experiment :
This is also known as Mariotte's law or in the other words it is also known as Boyle–Mariotte law.
This law tell us about the variation of gas pressure when the volume of the gas changes at the constant temperature.According to this law the abslute pressure is inversely proportional to the volume .
We can say that
Where P=Pressure
V=Volume
PV = K
K=Constant
When volume decrease then the pressure of the gas will increase.
That is why the answer is "Volume".
