A guitar string with a linear density of 0.0020 kg/m is stretched between supports that are 0.58 m apart. The string is observed to form a standing wave with three antinodes when driven at a frequency of 424 Hz.
(a) What is the frequency of the fundamental mode of vibration of this string?
(b) what is the speed of the wave on the string?

he kicked it 10 feet straight up into the air? i think this works.

true is the correct answer

hope i

your answer is c! hope this : )

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
