Answer:
32.5 m/s
Explanation:
Velocity of a wave = frequency * wavelength
Velocity = 65 /s * 0.5 m
Velocity = 32.5 m/s
Answer: B. the isovolumetric process
Explanation:
In the graph given, the volume is constant throughout. It represents a constant volume process. Such processes are called the isovolumetric process or isochoric process.
<em>Hence, option B is the correct answer.</em>
Option A is incorrect because in an isobaric process, the pressure is constant.
Option C is incorrect because in an isothermal process, the temperature is constant.
Option D is incorrect because in an adiabatic process there is no heat transfer.
Answer:False
Explanation:
the intensity of the sound wave decreases with increasing distance from the source.
