What is the value of the magicPowers variable after executing the following code snippet? String magicPowers = ""; int experienc
Evgen [1.6K]

Answer:

Shining lantern Magic beans                

Explanation:

I will explain the code line by line.

The first statement contains a string type variable magicPowers and second statement has an int type variable experienceLevel which is initialized by value 9.

Nested if statement are used and lets see which of those statements execute.

The first if statement checks if the value of experienceLevel is greater than 10. This statement evaluates to false because the value of experienceLevel is set to 9. Then the program control moves to the next if statement.

The second if statement checks if the value of experienceLevel is greater than 8. This if condition evaluates to true because the value of experienceLevel  is 9. So this if statement is executed which contains the statement magicPowers = magicPowers + "Shining lantern "; . This means magicPowers stores the string Shining lantern.

The third if statement checks if the value of experienceLevel  is greater than 2. As the value of experienceLevel  is 9 so this condition also evaluates to true which means the statement magicPowers = magicPowers + "Magic beans "; is executed. This statement means magicPowers stores the string Magic Beans

You can use a print statement to display the output on the screen as:

System.out.print(magicPowers);

Output:

Shining lantern Magic beans        

The program along with the output is attached as a screenshot.

Which quantity does a charge-coupled device measure?
NikAS [45]

Explanation:

A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging.

A mass of 12 kg saturated refrigerant-134a vapor is contained in a piston-cylinder device at 240 kPa. Now 300 kJ of heat is tran
Ket [755]

Answer:

I = 12.706 Amps

Explanation:

Given:

- The mass of saturated R-134a m = 12 kg

- The initial Conditions

      P_1 = 240 KPa

      Saturated Vapor

- The final Conditions

      P_2 = 240 KPa

      T_2 = 70° C

- The amount of Heat transferred Q_in = 300 KJ

- The voltage of current source V = 110 V

- The current supplied by the source = I

- The time duration Δt = 6 min

Find:

Determine the current supplied I.

Solution:

- Look-up enthalpies h_1 and h_2 at both states using Tables A-11 and A-13.

       P_1 = 240 KPa    

       Saturated Vapor ----------> h_1 = h_g = 247.32 KJ/kg

       P_2 = 240 KPa

       T_2 = 70° C        ----------> h_2 = 314.53 KJ/kg

- Using First Thermodynamic Law, set up an energy balance:

                           E_in - E_out = ΔE_system

                           Q_in + W_electric,in - W_out = Δ U

                           Q_in + V*I*Δt - W_out = Δ U

                           Q_in + V*I*Δt = Δ H

                           Q_in + V*I*Δt = m*( h_2 - h_1 )

- Make the current I the subject of the expression above:

                            V*I*Δt = m*( h_2 - h_1 ) - Q_in

                            I = [ m*( h_2 - h_1 ) - Q_in ] / V*Δt

- Plug in the values in the expression derived above and evaluate current of source I:

                            I = [ 12*( 314.53 - 247.32 ) - 300 ]*1000 / 110*6*60

                            I = 12.706 Amps                              

- The required source of current is I = 12.706 Amps.

A piston–cylinder device contains 15 kg of saturated refrigerant-134a vapor at 280kPa. A resistance heater inside the cylinder w
attashe74 [19]

Answer:

18.77 A

Explanation:

To solve this we use the energy balance equation, that is:

E_{in}-E_{out}=\Delta E_{sys}\\\\Q_{in}+W_{in}+W_{out}=\Delta U\\\\Q_{in}+W_{in}=\Delta U\\\\But\ W_{in}=Voltage(V)*Current(I)*change\ in\ time(\Delta t)=VI\Delta t,\Delta U=m(h_2-h_1)\\\\Given\ that\ m=15kg,V=110\ V,\Delta t=6\ min = (6*60\ s)=360\ s,Q_{in}=20.67\ kJ/kg*15\ kg=310.05\ kJ=310050\ J\\\\From\ table: At\ P_1=280kPa, h_1=249.71\ kJ/kg=249710\ J/kg;At\ P_2=280kPa \ and\  T_1=75^oC,P_2=319.95\ kJ/kg=319950\ J/kg\\\\Substituting:\\\\310500+(110*360*I)=15(319950-249710)\\\\

39600I=1053600-310500\\\\39600I=743100\\\\I=18.77\ A
