A circuit with ____ -diameter connecting wires at a _____ temperature will have the least electrical resistance.

Engineering
1 answer:
ELEN [110]3 years ago
7 0

Answer:

2. high or low

Explanation:

A circuit with high-diameter connecting wires at a low temperature will have the least electrical resistance.

According to Ohm's law, the current flowing through a current carrying conductor is directly proportional to the potential difference across its terminal and inversely proportional to resistance at a constant temperature.

Mathematically, V = IR.

Where;

V = Voltage

I = Current

R = Resistance

Some of the factors affecting resistance of a wire are;

- The resistance of a conducting wire is inversely proportional to its cross-sectional area (diameter).

- The resistance of a conducting wire is directly proportional to its temperature.

The thermodynamic property used to determine the amount of work produced by a power turbine in a heat engine is:_______
Sveta_85 [38]

Answer:

Enthalpy

Explanation:

Thermodynamic properties could be Intensive or extensive properties. Intensive properties are those that don't depend on the quantity of matter. Examples are pressure & temperature. Meanwhile, extensive properties are those whose values depend on the mass of the system. Examples are Energy, enthalpy and volume.

Now, in turbines in thermodynamics, the work done is produced by the flow required to turn the turbine and shaft. Recall that from the law of conservation of energy, the work in the turbine per mass airflow would be equal to the change in specific enthalpy of the flow from the entrance to the exit point of the turbine.

Thus, the property required to determine the work is Enthalpy.

A charge of 11.748 nC is uniformly distributed along the x-axis from −2 m to 2 m . What is the electric potential (relative to z
svp [43]

Answer:

electric potential  =  22.36 volt

Explanation:

given data

charge Q =  11.748 nC

distance d = 5 - 2 = 3 m

length = 2 + 2 = 4 m

Coulomb constant = 8.98755 × 109 N·m²/C ²

solution

electric potential is express as

electric potential  = \frac{Q}{4\pi \epsilon  _o L} ln(1+\frac{L}{d})   ..............1

electric potential  = \frac{KQ}{L} ln(1+\frac{L}{d})  

put here value

electric potential  = \frac{8.98755\times 10^9\times 11.748\times 10{-9}}{4} ln(1+\frac{4}{3})  

electric potential  =  22.36 volt

Write a function which multiplies the values in odd position values by 10. Odd positions in this case refers to the first value
xxMikexx [17]

Answer:

Using linkedlist on C++, we have the program below.

Explanation:

#include<iostream>

#include<cstdlib>

using namespace std;

//structure of linked list

struct linkedList

{

  int data;

  struct linkedList *next;

};

//print linked list

void printList(struct linkedList *head)

{

  linkedList *t=head;

 

  while(t!=NULL)

  {

      cout<<t->data;

      if(t->next!=NULL)

      cout<<" -> ";

     

      t=t->next;

  }

}

//insert newnode at head of linked List

struct linkedList* insert(struct linkedList *head,int data)

{

  linkedList *newnode=new linkedList;

  newnode->data=data;

  newnode->next=NULL;

 

  if(head==NULL)

  head=newnode;

  else

  {

      struct linkedList *temp=head;

      while(temp->next!=NULL)

      temp=temp->next;

     

      temp->next=newnode;

     

      }

  return head;

}

void multiplyOddPosition(struct linkedList *head)

{

  struct linkedList *temp=head;

  while(temp!=NULL)

  {

      temp->data = temp->data*10; //multiply values at odd position by 10

      temp = temp->next;

      //skip odd position values

      if(temp!= NULL)

      temp = temp->next;

  }

}

int main()

{

  int n,data;

  linkedList *head=NULL;

 

// create linked list

  head=insert(head,20);

  head=insert(head,5);

  head=insert(head,11);

  head=insert(head,17);

  head=insert(head,23);

  head=insert(head,12);

  head=insert(head,4);

  head=insert(head,21);    

 

  cout<<"\nLinked List : ";

  printList(head); //print list

 

  multiplyOddPosition(head);

  cout<<"\nLinked List After Multiply by 10 at odd position : ";

  printList(head); //print list

 

  return 0;

}

Air enters a constant-area combustion chamber at a pressure of 101 kPa and a temperature of 70°C with a velocity of 130 m/s. By
Norma-Jean [14]

Answer:

451 kj/kg

Explanation:

Velocity = 139m/s

Temperature = 70⁰C

T = 343K

M1 = v/√prt

= 130/√1.4x287x343

= 130/√137817.4

= 130/371.2

= 0.350

T1/To1 = 0.9760

From here we cross multiply and then make To1 the subject of the formula

To1 = T1/0.9760

To1 = 343/0.9760

To1 = 351.43

Then we go to the rayleigh table

At m = 0.35

To1/To* = 0.4389

To* = 351.43/0.4389

= 800k

M2 = 1

Maximum amount of heat

1.005(800-351.43)

= 450.8kj/kg

= 452kj/kg
