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
Speed = wavelength × frequency
giving that frequency is 0, wavelength and speed are directionally proportional. wavelength decrease = speed decrease
The three parts of the ear anatomy are the outer ear, the middle ear
and the inner ear. The inner ear is also called the cochlea. (‘Cochlea’
means ‘snail’ in Latin; the cochlea gets its name from its distinctive
coiled up shape.)
The outer ear consists of the pinna, ear canal and eardrum
The middle ear consists of the ossicles (malleus, incus, stapes) and ear drum
The inner ear consists of the cochlea, the auditory (hearing) nerve and the brain
Sound waves enter the ear canal and make the ear drum vibrate. This
action moves the tiny chain of bones (ossicles – malleus, incus, stapes)
in the middle ear. The last bone in this chain ‘knocks’ on the membrane
window of the cochlea and makes the fluid in the cochlea move. The
fluid movement then triggers a response in the hearing nerve.

Velocity = distance / time
v = (15*1000)m / (2*60*60)s
v=2.08 m / s
