The longest pipe found in most medium size pipe organs is 4.88 (16 ft) long. what is the frequency of the note corresponding to the fundamental mode if the pipe is open at one end and closed at the other?

a) 17.6 hz

b) 14.3 hz

c) 19.8 hz

d) 25.1 hz

option A

Explanation:

given,

length of the longest pipe = L = 4.88 m

speed of sound = 344 m/s

pipe is open at one end and closed at the other

frequency = ?

frequency of standing wave for the pipe opened at the one end and closed at the other.

v = velocity of wave

n = nth harmonic  n = 1

L is the length of pipe

f is frequency

Hence, the correct answer is option A

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

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
