Ques. the frequencies of sounds produced from two
different sources in medium p are 340hz and 400 hz
and the difference of their wavelengths is 0.165 m. in
another medium q the velocity of sound is 400ms.
[r. b.-2017]
a. what is called contact force?
b. explain the relation between the velocity of
sound with the nature of medium.
c. find out the velocity of sound in medium? 3
d. if the difference of wavelength of same sound in
both media is 0.1m, then will the wave travel the
distance 124 m in medium q by 80 complete
vibrations? give opinion through mathematical
analysis.

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:
