A concert loudspeaker suspended high off the ground emits 31 W of sound power. A small microphone with a 1.0 cm^2 area is 42 m f
Aleonysh [2.5K]

Answer:

intensity of sound at level of microphone is 0.00139 W / m 2

sound intensity level at position of micro phone is 91.456 dB

EXPLANATION:

Given data:

power of sound   P = 31 W

distance betwen microphone & speaker is   42 m

a) intensity of sound at microphone is calculated as

                   I = \frac{P}{A}

                   = \frac{34}{4 \pi ( 44m )^ 2}

                   =  0.00139 W / m 2        

b) sound intensity level at position of micro phone is

                \beta = 10 log \frac{I}{I_o}

    where I_o id reference sound intensity and taken as

                = 1 * 10^{-12} W / m 2  

               \beta = 10 log\frac{0.00139}{10^[-12}}

                     = 91.456 dB

Explain diffraction at a single slit (light)
Leto [7]

Answer:

At some point on say, the receiving screen, light emanating from the left side of the slit will be out of phase (a difference of 1/2 wavelengths) from   light coming from the center of the slit.

Thus for every point that is left of the center of the slit, there will be a point on the right side of the slit that is out of phase,

There will be no light on the screen at that particular point and thus there will be a dark fringe there.

That is the basic explanation for the appearance of dark and bright fringes on the receiving screen.

When a train first starts going down the railroad, it is very difficult for it to get going. When it comes to a stop, it has a h
Sindrei [870]
<h2>The option ( c ) is correct</h2>

Explanation:

When we apply the force on any body , the inertia comes into play . It is the tenancy of the the body to oppose the force which tends to change its state .

In first case the train tries to change its state from rest to motion . Thus the inertia of rest opposes this tendency.

In the second case , the train tries to come from motion to the state of rest . Thus again , inertia opposes it .

Therefore inertia is the factor which creates difficulty in both case . Hence option ( c ) is correct
