Answer:
Natural frequency=21.40 Hz
Time= 0.2936 seconds
Explanation:
Idealizing the question as a cantilever beam with point load of mass M as 20 tons
Lateral stiffness, where l is length given as 10 m, E is Young’s modulus given as 30GPa and I is inertia where for a circular cross-section is given by
k== 9160884.178
k=
To find the frequency, , the mass m is given as 20 tons or 20000 Kg
=21.40196741 Hz
Natural frequency=21.40 Hz
Time period,
T==0.2935798 seconds
T=0.2936 seconds
The answer is Solvent. The reason is in the wording, 'the substance that does the dissolving.' A solvent does the dissolving, a solute is something that can be dissolved.
Hey
in the summer it is because of the meting of snow
in the spring it is rain
hope l helped
Answer:
i only wrote this for points
Explanation:
Answer:
observed frequency = 109.68 Hz
Explanation:
given data
speed u = 20.9 m/s
frequency f = 103 Hz
solution
we consider here speed of sound (v) is 343 m/s
so observed frequency is express as
observed frequency = f × ...............1
put here value and we get
observed frequency = 103 × \frac{343}{343-20.9}
observed frequency = 109.68 Hz
