Answer:

350 m/s

31°C

Explanation:

Speed of sound is given as the product of frequency and wavelength

S=fw

Where s represent the speed in m/s, f is frequency and w is wavelength

Conversion

Taking 1m to be 100 cm then 35 cm will be 35/100=0.35m

Substituting 0.35 m for w and 1000 Hz for f then

S=1000*0.35=350 m/s

speed of sound (m/s) = 331.5 + 0.60 T(°C)

350=331.5+0.6T

T=30.833333333333

The temperature is approximately 31°C

The speed of the wave is 350 m/s.

The temperature of the air is 31°C.

Calculation of the speed and temperature:

We know that

Speed of sound should be provided as the product of frequency and wavelength

i.e.

S=fw

Here

s means the speed in m/s,

f is frequency

and w is wavelength

Now

we know that 1m to be 100 cm

So,  35 cm will be 35/100=0.35m

Now the speed is

S=1000*0.35

=350 m/s

Now

speed of sound (m/s) = 331.5 + 0.60 T(°C)

And, finally the temperature is

350=331.5+0.6T

T=30.83

T = 31
