Which statement is true for a sound wave entering an area of warmer air?

Physics

Georgia [21]3 years ago

Answer:

E. The wave travels faster and with an increased wavelength.

Explanation:

As we know speed of the sound depends on the temperature of medium, higher the speed of sound more will be the temperature.

As the sound enters an area of warmer temperature, that molecules of that area posses high kinetic energy hence they vibrate faster resulting an increase in speed of sound. Now more the speed, more will be the wavelength.

Hence when sound wave enters an area of warmer air it will travel with a faster speed  and with an increased wavelength.

The appropriate response is letter D. The wave ventures slower and with an expanded wavelength when a sound wave entering a range of hotter air. Hotter air implies less thick, so the wave ought to back off.

I hope the answer will help you, feel free to ask more in brainly.

Svetllana [295]

Answer:

a. 4v

Explanation:

Alf moves with speed v

Alf travel during the same amount of time that is Δt = (1/4)s

v = (1/4)s /  Δt = s / 4 Δt

s / Δt  = 4 v

Beth travels a distance s during time Δt,

speed of Beth = s / Δt = 4 v .

How much time does it take a rhino running at 40 m/s to run 250 m?​
lions [1.4K]

Answer:

Rhinoceroses are odd-toed ungulates native to sub-Saharan Africa and southern Asia, though all five living species have hugely contracted in range and number due to the influence of humans. Despite their titanic, tank-like bulk, rhinos can be amazingly swift: The fastest may reach at least 50 kilometers per hour (31 mph).

Calculate the velocity of a wave that has a frequency of 60 Hz and wavelength of 2.0 m/s
mote1985 [20]

Answer:We have , a relation in frequency f and wavelength  λ of a wave having the velocity v as ,

           v=fλ ,

given f=60Hz , λ=20m ,

therefore velocity of wave , v=60×20=1200m/s
