Answer:

Explanation:

(1/3x-1/6y)×18=4×18 ⇒ 6x-3y=72

6x-ay=8 if a=3 ⇒ 6x-3y=8

72≠8

a=3 ⇒ system has no solution

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

Which statements are true according to the law of demand? An increase in supply leads to an increase in demand. A decrease in su

g100num [7]

The correct statements are:<span>
</span>
<span>An increase in price leads to a decrease in quantity demanded
</span>
and

<span>A decrease in price leads to an increase in quantity demanded</span>

According to the laws of demand and supply, if the price of any product/service is increased there would naturally be less demand for such a product.

As a natural human response, we avoid products that get expensive and opt for cheaper options.

Also, if the price of a product/service decreases, there would be more demand for such a product as more people will be able to buy it.

Dahasolnce [82]

A a result of bridging finance, extension requests is said to be more popular as borrower kept coming back to request an extension.

<h3>Why do a lot of businesses still borrow money despite the cost?</h3>

The act of borrowing is one that helps to provide businesses with a lot of added expense, which they can use for any investment that can make them to generate a lot of money than the costs it took them to borrow.

And as such, due to the above, there is more improved access or means to working capital that is needed by businesses to take advantage of new opportunities as they are said to arise.
