Answer:

Explanation:

Given

Mechanical Energy of Spring-Block system is 1 J

Maximum Amplitude is A=10 cm

maximum speed v_{max}=1.2 m/s

Suppose x=A\sin \omega tbe general equation of motion of spring-mass system

where A=max amplitude

\omega=Natural frequency of oscillation

t=time

v_{max}=A\omega =1.2

0.1\cdot \omega =1.2

\omega =12 rad/s

maximum kinetic Energy must be equal to total Mechanical Energy when spring is un deformed i.e. at starting Position

\frac{1}{2}mv_{max}^2=1

m=\frac{2}{1.2^2}=\frac{2}{1.44}=1.38 kg

Also \omegais also given by

\omega =\sqrt{\frac{k}{m}}

k=\omega ^2\cdot m

where k= spring constant

k=12^2\cdot 1.38

k=200 N/m

An open organ pipe is 2.46 m long, and the speed of the air in the pipe is 345 m/s.
lukranit [14]

Answer:

Fundamental frequency is 70.12 m

Explanation:

For an open organ pipe, the fundamental frequency is given by :

f=\dfrac{nv}{2l}

n = 1 for fundamental frequency

v is speed of sound in air, v = 345 m/s

l is length of open organ pipe, l = 2.46 m

Substituting values in above formula. So,

f=\dfrac{1\times 345}{2\times 2.46}\\\\f=70.12\ Hz

So, the fundamental frequency of this pipe is 70.12 m.
