1. Write an equation that shows the equivalency between meters and Gigameters.

The bulk modulus of a fluid if it undergoes a 1% change in volume when subjected to a pressure change of 10,000 psi is (a) 0.01

Veseljchak [2.6K]

Answer:

The required bulk modulus is $10^{6}$ Psi. So, the answer is non of these.

Explanation:

Change in pressure of the fluid is directly proportional to the volumetric strain. The constant of proportionality is the bulk modulus of the fluid.

Step1

Given:

Percentage change in volume is 1%.

Change in pressure is 10000 Psi.

Calculation:

Step2

Volumetric strain is calculated as follows:

$\frac{\bigtriangleup V}{V}=\frac{1}{100}$

$\frac{\bigtriangleup V}{V}=0.01$

Step3

Bulk modulus is calculated as follows:

\frac{\bigtriangleup V}{V}=0.01

$\frac{\bigtriangleup V}{V}=0.01$

$10000=K\times0.01$

K = 1000000 Psi.

Thus, the required bulk modulus is $10^{6}$ Psi.

For the given network, if R = 0.8 [Ω], the natural response of i in(t) is:

11111nata11111 [884]

Answer:

Iin(t) =1.3 × (-0.8/1.56) e^-t/1.56 A

Explanation:

In physics, the determination of the term " natural response" simply means that we want to know what happens in a circuit when the value of t = 0, that is to say after the circuit has been disconnected. Hence, the value of the voltage and the current can then be determined or Calculated;

For the the natural response of i in(t) we will be using the formula below;

I(t) = Vo × t/ R = Vo/R × e^-t/h.

Where h = 1/RC = time constant.

For t= 0^- = 0.8 × 1= 0.8 V.

1/Ctotal = 1/ 2 + 1/3 = 6/5

For t = 0^+;

h =( 0.8 + 0.5) × 6/5 = 1.56 seconds.

Hence, we will have;

Vin(t) = 0.8 × e^-t/1.56.

Iin(t) =1.3 × (-0.8/1.56) e^-t/1.56

The following information pertains to the January operating budget for Casey Corporation. ∙ Budgeted sales for January $200,000

stich3 [128]

Answer:

For January, budgeted cost of goods sold is $150,000

Explanation:

Sales is the consists of Gross income and Cost of goods sold. We can derive the gross income value after deducting cost of goods sold from sales value.

Budgeted Sales for next month = $200,000

Gross Margin = 25%

Gross Margin = Gross Income / Sales

25% = Gross Income / $200,000

Gross Income is the net value of sales and cost of goods sold.

Gross Income = $200,000 x 25%

Gross Income = $50,000

As we know,

Gross Income = Sales - Cost of Goods sold

$50,000 = $200,000 - Cost of Goods sold

Cost of Goods sold = $200,000 - $50,000

Cost of Goods sold = $150,000
