Negative outcomes of optimism typically include: (check all that apply. ).

TEA [102]

Answer:

First off, well-being is defined as the overall evaluation a person makes regarding their life and emotional experiences. It's the combination of "feeling good" or positive affect, low levels of negative affect or negative feelings, and life satisfaction (a broad cognitive appraisal regarding one's life). A part of well-being is determined by the direct attempt that people make to influence their own well-being (their internal actions). 3 ways out of many that people can do this is through optimism, positive emotions, and forgiveness.

A linear machine is connected as shown in Fig. 1. The input source voltage Vin=10V, the internal resistance Rin=0.05Ω. The appli

galina1969 [7]

It is important to note that the direct of flow of the electricity current in the Linear Machine is anti-clockwise direction. The resultant effect of this is such that is stand at variance with the change in flux as force is going the right direction. See attached Image (Illustration I).

<h3>What is the magnitude of the current?</h3>

Recall that Force (f) = il xB

Given that Force (F) = 10N; and

Magnetic Field Density B = 0.5T

Hence,

10 = i x 0.2 x 0.5

[Note that Width is converted to Meters from millimeters that is 200 mmm = 0.2m]

10 = 0.1i

i = 10/0.1

i = 100A

<h3>What is the Induced Voltage Across the metal bar?</h3>

Note that Vg = Vde + IR

Vg = 10 + 100 x 0.05

Vg = 10 + 5

Vg = 15v

<h3>What is the final speed of the metal bar?</h3>

The final speed of the bar is given as V

Recall that Induced Voltage is VB x L

That is:

15 = V x 0.5 x 0.2;

15 = 0.1 V

make V the subject of the formula:

V = 15/0.1

V = 150m/s

<h3>What is the status of the Machine? a motor or generator?</h3>

Given that the current being supplied is in DC hence the machine is a generator. [Vdc x i]

<h3>What is the electric power of the source?</h3>

The electric power of the source is:

Vdc x i

= 10 x 100

= 1,000 watts
