Organ pipe A, with both ends open, has a fundamental frequency of 360 Hz. The third harmonic of organ pipe B, with one end open, has the same frequency as the second harmonic of pipe A. How long are (a) pipe A and (b) pipe B? (Take the speed of sound to be 343 m/s.)

The length of the pipe A is = 0.4763 m &  the length of the pipe B is 0.357 m

Explanation:

Fundamental  frequency  = 360 Hz

Velocity = 343

(a). Length of the pipe is given by

Put all the values in above equation we get

= 0.4763 m

(b). Given that

The third harmonic of organ pipe B = the second harmonic of pipe A

Thus

Put all the values in above formula we get

0.357 m

Therefore the length of the pipe A is = 0.4763 m &  the length of the pipe B is 0.357 m

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.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
