A guitar string of mass mm under tension resonates in its fundamental mode outside the ear canal and the string produces resonance in the ear's fundamental mode and so is perceived at maximum loudness. A second guitar string of different mass but of the same length and under the same tension again vibrates in the fundamental mode. The new string is designed to produce a resonance in the next higher harmonic of the ear. What should be the mass of the the new string in terms of the original mass mm

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

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
