Explained

Explanation:

According to the humanistic perspective securing the future motivates the individuals the most.

All we humans do in our life is somehow trying to secure a future for our selves and our children.

let me explain to you how this happens, basically all our lives we try to get the best education and work hard. Why is that so? It is because we get knowledge and can get some good profession?

But what does a good profession guarantees us? That is monetary and other such benefits, but what do we have to do with all of the money. That is to secure our future. So basically we want to make our future better.

Rzqust [24]

Time = (20 km) x (1 hr/2 km) x (3,600 sec/hr)

Time = (20 x 1 x 3,600 km-hr-sec) / (2 km-hr)

Time = (20 x 1 x 3,600 / 2) (km-hr-sec / km-hr)

Time =<em> 36,000 seconds</em>

(That's 10 hours.)

Loudspeakers can produce intense sounds with surprisingly small energy input in spite of their low efficiencies. Calculate the p

Dennis_Churaev [7]

Answer:

$5.87*10^{-4}W$

Explanation:

Given that:

$\beta = 89,6 dB$

$D = 13.0 cm$

$r = \frac{D}{2}\\ = \frac{13.0}{2}\\ = 6.5 cm\\=0.065m$

Efficiency = 2.06 % = 0.0206

The intensity level of sound is given by the formula:

$\beta = (10dB) log (\frac{I}{I_o} )$

$\frac{\beta}{(10dB) } =log (\frac{I}{I_o} )$

Taking their exponential; we have :

$10^{\frac{\beta}{10dB}}= \frac{I}{I_o}$

$I = I_o(10^{\frac{\beta}{10dB}})$

Replacing our values; we have:

$I = (10^{-12}W/m^2)(10^{\frac{89.6}{10dB}})$

$= 9.12 *10^{-4}W/m^2$

Power Output;

$P_{out} = IA\\P_{out}=I(\pi r^2)\\P_{out}=(9.12*10^{-4}W/m^2)(3.14)(0.065m)^2\\P_{out}=1.2099048*10^{-5} W$

The power output that is required to produce a 89.6 dB sound intensity level for a 13.0 cm diameter speaker that has an efficiency of 2.06% is;

$P_{in}= \frac{P_{out}}{0.0206}$

$P_{in}= \frac{{1.2099048*10^{-5}}}{0.0206}$

$P_{in}= 5.87*10^{-4}W$

Therefore, The power output that is required to produce a 89.6 dB sound intensity level for a 13.0 cm diameter speaker that has an efficiency of 2.06% is $5.87*10^{-4}W$
