The speed of sound in gases is represented mathematically as:
v(sound) = √γRT/M
where γ = adiabatic constant which is the ratio of the heat capacities at constant pressure and constant volume; Cp/Cv
R = gas constant
T = temperature
M = molar mass of the gas
Hence, the speed of sound in gas is directly proportional to the square root of temperature.
Ans: c) temperature
T = 3 h = 3 x 3600s = 10800s
d = 100 x 10800 = 1080000km to The east.
Answer:
1.5 m/s.
Explanation:
The Speed of a wave is the product of the wavelength and its frequency or it is the ratio of it wavelength and its Period. It can be expressed mathematically as
V = λf or λ/T .............................. Equation 1
Where V = speed of the wave travelling on the string, λ = wavelength of the wave, T = period of the wave, F = frequency of the wave.
Given: λ = 1.8 m ( distance it takes to repeat itself), T = 1.2 s (Time taken to complete a full cycle)
Substitute into equation 1
V = 1.8/1.2
V = 1.5 m/s.
Hence the wave is 1.5 m/s fast.
