What is a Planck Distribution and how is it used to solve for black body radiation problems?
zvonat [6]

Answer:

Planks law:

   Planks law gives the theoretical distribution for emissive power of black body.The emissive power for is given as follows

Planks distribution as a function of wavelength for different temperature.

E_{\lambda,b}=\dfrac{C_1}{\lambda^5 [exp{\frac{C_2}{\lambda T}-1}]}

Where C_1 andC_2 is the constant.

Important points for Planks distribution

1.At the given wavelength when temperature increases then emissive power will increase.

2.When temperature is increases then then distribution shift towards the left side.

3. We can assume that sun as a black body at  5800 K.

Under conditions for which the same roojm temperature is mainteined bt a heating or cooling system, it is not uncommon for a per
bonufazy [111]

Answer:

Net heat transfers:  during summer = 52.253 W/m^2 during winter = 119.375 w/m^2

Explanation:

Given data :

Room temperature throughout the year = 20⁰c = 293 k

Room temperature during summer = 27⁰c = 300 k

Room temperature during winter = 14⁰c = 287 k

surface temperature of a person throughout the year = 32⁰c = 305 k

coefficient of heat transfer by natural convection (h)= 2 w /m^2 k

emissivity = 0.9

An explanation to the condition of feeling chilled during the winter and comfortable during summer  can be explained with the calculation below

The heat transfer from the surface body of a person the the room is carried out by convection and this can be calculated as

q = hΔt = 2 * ( 305  -  293) = 2 * 12 = 24 w /m^2

also calculate heat transfer through radiation using this formula

q_{rad} = εσ [ (Temperature of body)^4- (temperature of room at each season)^4 ]

ε = 0.90,(emissivity)    σ = 5.67 *10^-8 w/^2 . k ( Boltzmann's constant)

during summer :

q_{rad} = (0.90)*(5.67*10^-8)* ( 305^4 - 300^4 ) = 28.253 W/m^2

therefore the net heat transfer during the summer = 24 w/m^3 + 28.253 W/m^3 = 52.253 W/m^2

During winter :

q_{rad} = (0.90)*(5.67*10^-8) * ( 305^4 - 287^4 ) = 95.375 W/m^3

therefore the net heat transfer during the winter

= 24 w/m^3 + 95.375w/m^3 = 119.375 w/m^2

ZanzabumX [31]

Answer:

The correct option is;

B. Word painting

Explanation:

Word painting is the musical art of composition of music literally describing by reflection the action of the lyrics of the music. Word painting is also referred to as text painting or tone painting. Word painting is a technique commonly used in Renaissance music such as madrigals and the technique of word painting can also be found in church music such as in Hendel's Messiah

An example of word painting is where ascending set of musical notes will be paired with lyrics about increasing.
