igomit [66]

Answer:

6.6516 W

Explanation:

The film temperature is given as the average of the two temperatures, hence (43 + 17)/2 = 30°C.

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.

What is a core self-evaluation, include identifying and explaining the components of core self-evaluation. And, how a group lead

Brilliant_brown [7]

Answer and Explanation:

Core self-evaluations (CSEs) stands for a wide personality trait that comprises of 4 positive individual traits, namely:

(1) self-efficacy

(2) self esteem

(3) locus of control

(4) emotional stability.

Baiscally, when people have a positive evaluation about themselves, or quality core self-evaluation, they believe that they are worthy and fit for a task. They trust their capability and effectiveness. This leads to some implications in their managers duties and careers, which could either be positive or negative.

A group leader can use CSEs to create a more effective unit by implementing the ten items points of Generalized Self Efficacy Tool to test the self efficiency of individual personnels in that unit.

ddd [48]

Answer:

//Annual calendar

#include <string>

#include <iomanip>

void month(int numDays, int day)

{

for(i=0; i<7; i++)

{

cout << left << setw(1) << weekDays[i];

cout << "\n----------------------\n";

int firstDay = day-1;

//Space print
