A capacitor is connected across an ac source. suppose the frequency of the source is doubled. what happens to the capacitive reactance of the capacitor?.

Answers

Answer 1

Answer:

Explanation:

The capacitive reactance of the capacitor is determined by [tex]X_{C}=\frac{1}{\omega C}[/tex]

When [tex]f'=2f \rightarrow \omega' =2\omega[/tex]

and [tex]X_{C}'=\frac{1}{2}X_{C}[/tex]

(The capacitive reactance will be reduced into 1/2 times of the previous capacitive reactance)

A farmer has 12 hectares of land on which he grows corn, wheat, and soybeans. It costs $4500 per hectare to grow corn, $6000 to grow wheat, and $5000 to grow soybeans. Because of market demand the farmer will grow twice as many hectares of wheat as corn. He has allocated $6,375,000.00 for the cost of growing his crops. How many hectares of each crop should he plant?

Answers

The number of hectares of each crop he should plant are; 250 hectares of Corn, 500 hectares of Wheat and 450 hectares of soybeans

How to solve algebra word problem?

He grows corn, wheat and soya beans on the farm of 1200 hectares. Thus;

C + W + S = 12   ----(1)

It costs $45 per hectare to grow corn, $60 to grow wheat, and $50 to grow soybeans. Thus;

45C + 60W + 50S = 63750  -----(2)

He will grow twice as many hectares of wheat as corn. Thus;

W = 2C    ------(3)

Put 2C for W in eq 1 and eq 2 to get;

C + 2C + S = 1200

3C + S = 1200     -----(4)

45C + 60(2C) + 50S = 63750

45C + 120C + 50S = 63750

165C + 50S = 63750    ------(5)

Solving eq 4 and 5 simultaneosly gives;

C = 250 and W = 500

Thus; S = 1200 - 3(250)

S = 450

An electrochemical cell is composed of pure copper and pure cadmium electrodes immersed in solutions of their respective divalent ions. For a 6.5 × 10-2 M concentration of Cd2+, the cadmium electrode is oxidized, yielding a cell potential of 0.775 V. Calculate the concentration of Cu2+ ions if the temperature is 25°C.

Answers

From the calcuation, the concentration of the copper II ion is 0.98 M.

What is an electrochemical cell?

An electrochemical cell is one in which current is produced by means of a chemical reaction. In this cell, the cell reaction is;

Cd(s) + Cu^2+(aq) ----> Cd^2+(aq) + Cu(s)

E°cell = 0.34 V - (-0.40V) = 0.74 V

Using the Nernst equation;

0.775= 0.74 - 0.0592/2 log(6.5 × 10-2)/[Cu^2+]

0.775 - 0.74 =  - 0.0592/2 log(6.5 × 10-2)/[Cu^2+]

0.035 = -0.0296 log(6.5 × 10-2)/[Cu^2+]

0.035 /-0.0296 = log(6.5 × 10-2)/[Cu^2+]

-1.18 =  log(6.5 × 10-2)/[Cu^2+]

Antilog (-1.18) = (6.5 × 10-2)/[Cu^2+]

0.066= (6.5 × 10-2)/[Cu^2+]

[Cu^2+] =  (6.5 × 10-2)/0.066

A closed thermodynamic cycle consists of two isobaric and two isochoric processes. The processes operate between 0.43 MPa and 4.3 MPa and 0.28 m3 and 2.9 m3. Determine the total work (with appropriate sign) for one complete cycle, when the cycle operates in the clockwise direction. Provide your result in MJ.

Answers

Answer:

Explanation:

For first isobaric process (expansion with constant pressure):

[tex]W_{1}=P_{1}(V_{2}-V_{1})=(0.43\times 10^{6})(2.9-0.28)=1.1266 \times 10^{6} J=1.1266 MJ(+) (Expansion)[/tex]

Now, for the first isochoric: [tex]W_{2}=0[/tex], and [tex]Q_{2}=\Delta U=U_{3}-U_{2}[/tex]

For the second isobaric process (compression with constant pressure):

[tex]W_{3}=P_{2}(V_{1}-V_{2})=(4.3\times 10^{6})(0.28-2.9) =-11.266\times 10^{6}J=-11.266 MJ (Compression)[/tex]

For the last isochoric: [tex]W_{4}=0, Q_{4}=\Delta U=U_{4}-U_{3}[/tex]

So, the total work per cycle: [tex]W=W_{1}+W_{2}+W_{3}+W_{4}=1.1266+0-11.266+0=-10.1394 MJ[/tex]

Answers

The composition of the mixture on a mass basis are as follows:

He = 131.70 gN2 = 1140.41 gAr = 1054.68 g

number of moles = mass of substnce / molar mass

molar mass and molecular weight has equal numerical values therefore

Number of moles = mass of substnce / molecular weight

mass of substance = number of moles * molecular weight

the moles are expressed in percentage hence the total moles should be 100

check: 32.9 + 40.7 + 26.4 = 100

He

mass of substance = 32.9 * 4.003 = 131.6987 g
