Find intensity of sound when power output is given

Answer»

There has been a major MISSING ingredient so far in our discussion of quantifying loudness, making the connection between the amplitude of the SOUND wave (sound pressure) and the qualitative notion of loudness. We have talked about sound at a PARTICULAR point (in a room, on a city street, or near an airport listening to jets taking off) without worrying about how the sound is produced. Connecting loudness to the source of sound energy is important, because as we know from our direct experience, how loud we perceive a produced sound DEPENDS on the distance between the source and our ear. Today, we'll QUANTIFY how loudness depends on the amount of sound energy produced and the distance between the source and our ear

How to determine brightness of bulbs in circuits?

Answer»

Both the current and VOLTAGE contribute the BRIGHTNESS there is a relation between voltage and current it just DEPENDS CONFIGURATION

3.

How can we get dimensional formula of wave velocity?

Answer» VELOCITY= DISPLACEMENT / time

Since DIMENSION of displacement is [L]

And TIMES dimension is [T]

So dimension of velocity= [L]/[T] = [LT^-1]

Which method for circuit analysis is best and why

Answer»

Hello friend here is your
an ELECTRICAL ENGINEERING student, and CIRCUIT analysis can be really confusing to me. I sort of understand the concepts of solving circuits, but I don't really know when to use which method. Are there any simple rules on choosing which method I should use for solving circuits? Node-voltage analysis? Superposition? Mesh analysis? Just use reduced linear equation system (or whatever it's called in English)?

Should I just calculate how many equations each method will take and pick the ONE with least equations?

Also, how do I know if I should use Thevenin's / Norton's generator to substitute a network?

Please note that this is not really for practical purposes - I'm studying for an exam, but all the assignments in my textbook are categorized by methods, so I know which one to use. However, in the exam that info is not given to students.

Thanks.

i HOPE it will help you

How can we find lenght using perimeter and breadth?

Answer»

Let’s CONSIDER an example:
If length of a rectangle is 10 cm and its perimeter is 22 cm, then find its BREADTH.
Given length, l = 10 cm and perimeter = 22 cm
We know that perimeter of rectangle = 2 (l + b) units
22 = 2(10 + b)
⇒ 10 + b = 11
⇒ b = 1 cm
Hence breadth of the rectangle is 1 cm.
In general, perimeter of rectangle P = 2(l + b)
(P/2) = l + b
⇒ b = (P/2) – l
Using above formula ALSO you can directly find the value of breadth......

Why is vanishing and exploding gradient problem for relu

Answer»

The vanishing gradient problem affects saturating neurons or units only. For example the saturating sigmoid activation function as given below.

S(t)=11+e−tS(t)=11+e−t

You can easily prove that

S(t)t→∞=1.0S(t)t→∞=1.0

and

S(t)t→−∞=0.0S(t)t→−∞=0.0

Just by inspection. This is a saturation effect that becomes problematic as explained below, consider the first order derivative of the sigmoid function.

S′(t)=S(t)(1.0−S(t))S′(t)=S(t)(1.0−S(t))

Since S(t)S(t) ranges from 0.0 to 1.0, its lower and upper asymptotes respectively, then clearly the derivative will be near zero for S(t)≈0.0S(t)≈0.0 or S(t)≈1.0S(t)≈1.0. The vanishing gradient problem comes about when the error signal passes backwards and starts approaching zero as it propagates backwards especially through neurons near saturation. If the network is deep enough the error signal from the output layer can be completely attenuated on it’s way back towards the input layer.

The attenuation comes about because the derivative S′(t)S′(t) will always be near zero especially for saturating neurons, you do notice that if you use chain rule, which is backpropagation in neural net terms, you will somehow be multiplying this almost zero derivative with the error signal before throwing it backwards at every level or stage. Now keep doing that as you throw the error signal backwards and what you get is an error signal becoming weaker hence vanishing. Even the hyperbolic tangent has this saturating effect and hence the vanishing gradient problem also affects it.

Those units active in the linear region of the sigmoid won’t ATTENUATE the error signal that much but this is generally problematic for very deep nets.

That’s why ReLUs are favorable not only because they solve the vanishing gradient problem but also because they result in highly sparse neural nets. Sparsity means efficient and reliable performance. The rectifier is as given below.

f(x)={0,x,for x<0for x≥0f(x)={0,for x<0x,for x≥0

Clearly it ranges from 0 to positive infinity thus it is non saturating and the derivative is given by

f′(x)={0,1,for x<0for x≥0f′(x)={0,for x<01,for x≥0

It’s always 1 hence no attenuation of an error signal propagating backwards. This MAKES ReLUs favorable for the deeper trainable feature detectors as in ConvNets, you can have very deep neural nets with ReLUs without the vanishing gradient problem.

EDIT:

You do notice that the negative region has a zero derivative, right? This can be a problem as the neuron is off within this region and cannot learn and gradients cannot be backpropagated through an off neuron. There are remedies to this by adding a leakage factor which results in a non-zero derivative and thus resulting in a modified neuron known as the leaky ReLU.

Hope this helps.

Difference between maxwell boltzmann distribution and fermi dirac distribution

Answer»

apply to “CLASSICAL” particles with non-quantized energy levels.

Bose–Einstein statistics apply to quantum particles with the property that any NUMBER of particles can occupy any level. It turns out these are the particles with integral “spin” such as photons and He4 (but not He 3) atoms.

Fermi–Dirac statistics - apply to quantum particles with the property that only ONE particle can occupy any particular level. It turns out these are the particles with half-integral “spin” such as electrons and neutrons.

Both BE and FD statistics converge (from opposite directions) on MB statistics when the density of particles is small COMPARED to the Quantum concentration, where the inter-particle distance is COMPARABLE to the de Broglie wavelength

When a ball is freely fallen from a given height it bounces to 80%

Answer»

Let a BALL fall from a height h, thenKinetic energy of ball at the time striking the ground= POTENTIAL energy of ball at height h
so, K.E=mgh
Kinetic energy of ball due to rebounce will be :
K.Er =P.E of ball at height h1= mgh1
Loss of kinetic energy due to re-bounce=K.E -K.Er
=mgh -mgh1=MG(h-h1)=mg(h-80h/100)=mg(20h/100)= 0.2 x mgh
Fractional loss in K.E in each re-bounce will be :=K.E-K.Er/K.E=0.2 x mgh/mgh=0.2=0.2 x100% =20%
Fraction of its Mechanical energy LOST in each rebound is 20%
