Find the distance between two consecutive nodes if a string has tension 0.25 N, mass per unit length is 1 mg/m and frequency is 250 Hz.

An carthquake gencrates both transverse $(S)$ and longitudinal $(P)$ sound waves in the earth. The spced of $S$ waves is about $4.5 \,km / s$ and that of $P$ waves is about $8.0 \,km / s$. A scismograph records $P$ and $S$ wavcs from an carthquake. The first $P$ wave arrives $4.0\, min$ before the first $S$ wave. The cpicentre of the earthquake is located at a distance about

A boy standing between two cliffs claps and hear two echoes, the first after 2 seconds and the second after 3 seconds. The velocity of sound is 360 m/sec. The distance in meter between the two cliffs is

A closed organ pipe and an open organ pipe of same length produce $2 \,beats/second$ when they are set into vibrations together in fundamental mode. The length of open pipe is now halved and that of closed pipe is doubled. The number of beats produced will be

Two waves of wavelengths 50 cm and 51 cm produced 12 beats per sec. The velocity of sound is

Two uniform strings $A$ and $B$ made of steel are made to vibrate under the same tension. If the first overtone of $A$ is equal to the second overtone of $B$ and if the radius of $A$ is twice that of $B$, the ratio of the lengths of the strings is

A string in a musical instrument is $50\, cm$ long and its fundamental frequency is $800\, Hz$. If a frequency of $1000\, Hz$ is to be produced, then required length of string is

A person is observing two trains one coming towards him and other leaving with the same velocity $4\, m / s$. If their whistling frequencies are $240\, Hz$ each, then the number of beats per second heard by the person will be : (if velocity of sound is $320\, m / s$ )

The equation of stationary wave along a stretched string is given by $y=5\, \sin \frac{\pi x}{3} \cos 40\, \pi t$, where, $x$ and $y$ are in $cm$ and $t$ in second. The separation between two adjacent nodes is :
