The frequency of the middle c note on a piano is 261.63 hz. what is the wavelength of this note in centimeters? the speed of sound in air is 343.06 m/s.

1.31 m

Explanation:

The relationship between frequency and wavelength of a sound wave is

where

c is the speed of the wave

f is the frequency

is the wavelenfth

In this problem, we have

c = 343.06 m/s

f = 261.63 Hz

So we can solve the formula for the wavelength:

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
