Imagine you are shaking the end of a rope to create a series of waves what will you observe if you begin shaking the rope more quickly use the terms wave speed, frequency, and wavelength in your answer

Explanation:

In this case, consider that you are shaking the end of a rope to create a series of waves. A wave can be characterized by the following parameters i.e. the speed, frequency, amplitude and the wavelength.

If you begin shaking the rope more quickly, then the number of oscillations increases. The number of vibrations or oscillations is called the frequency of the wave.

If the frequency of the wave increases, its wavelength will decrease and hence the speed of the wave will increase. i.e. v = υ × λ.

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

the answer is 12 as i may remember
