Each rarefraction on a longitudinal wave correspond to what point on a transverse wave?

1 answer:

4 0

Answer: In a longitudinal wave, the crest and trough of a transverse wave correspond respectively to the compression, and the rarefaction. A compression is when the particles in the medium through which the wave is traveling are closer together than in its natural state, that is, when their density is greatest.

A physical pendulum in the form of a planar object moves in simple harmonic motion with a frequency of 0.290 Hz. The pendulum ha

BARSIC [14]

Answer:

1.4584 kg $m^2$

Explanation:

Time period of a physical pendulum is given by $T=2Π\sqrt{\frac{I}{mgd}}$

Here f=0.290 so $T=\frac{1}{F}=\frac{1}{0.29}=3.44827$

Mass =2.40 kg

d=0.300 m

g =9.8 m $sec^2$

So $3.448=2\times \pi \sqrt{\frac{I}{2.4\times 9.81\times 0.300}}=1.4584$ kg- $m^2$

So the moment of inertia of the pendulum about the pivot point will be 1.4584 kg- $m^2$

The problem is basically asking us to find a way to find the sound intensity I, in terms dependent on the sound level and the reference intensity $I_0$ .For this purpose we can start from the unit used in the scale logarithmic decibel, that is
