Answer:

Trojan horse

Explanation:

A trojan horse attack is a type of malware that misleads users, as it appears unsuspicious at first, but actually presents a threat to the user. A common example is that of an email that contains a malicious attachment. Another common example is that of a fake advertisement. The name comes from the Greek story of the Trojan horse that led to the fall of the city of Troy.

Suppose values is a sorted array of integers. Give pseudocode that describes how a new value can be inserted so that the resulti
Novosadov [1.4K]

Answer:

insert (array[] , value , currentsize , maxsize )

{

   if maxsize <=currentsize

  {

      return -1

  }

  index = currentsize-1

  while (i>=0 && array[index] > value)

  {

      array[index+1]=array[index]

      i=i-1

  }

 

  array[i+1]=value

  return 0

}

Explanation:

1: Check if array is already full, if it's full then no component may be inserted.

2: if array isn't full:

  • Check parts of the array ranging from last position of range towards initial range and determine position of that initial range that is smaller than the worth to be inserted.  
  • Right shift every component of the array once ranging from last position up to the position larger than the position at that smaller range was known.
  • assign new worth to the position that is next to the known position of initial smaller component.

Which of the following answer options is a hazard in using scaffolding?​
kenny6666 [7]

Answer:

One of the most common injuries that result from working on a scaffold is electrocution. If workers make contact with those wires while working, it can lead to electric shock, especially if that contact damages the wire or if the scaffold is made of metal.

3241004551 [841]

A model of living systems as whole entities which maintain themselves through continuous input and output from the environment, developed by ludwig von bertalanffy is known as Systems theory.

<h3>what are the application of systems theory?</h3>

It is a theoretical framework to understand the working mechanism of an organization.

It is an entity where all the elements necessary to carry out its functions.

A computer is the best  example of showing the mechanism of system theory.

computer is a system which has many smaller sub-systems that have to work in coordinated manner.

These sub-systems are the processor, RAM, motherboard, hard drive and power supply.

Steam enters an adiabatic turbine at 10MPa and 500 C and leaves at 10 kPa with a quality of 90%. Neglecting the changes in kinet
Amanda [17]

Answer:

flow ( m ) = 4.852 kg/s

Explanation:

Given:

- Inlet of Turbine

        P_1 = 10 MPa

        T_1 = 500 C

- Outlet of Turbine

        P_2 = 10 KPa

        x = 0.9

- Power output of Turbine W_out = 5 MW

Find:

Determine the mass ow rate required

Solution:

- Use steam Table A.4 to determine specific enthalpy for inlet conditions:

          P_1 = 10 MPa

          T_1 = 500 C            ---------- > h_1 = 3375.1 KJ/kg

- Use steam Table A.6 to determine specific enthalpy for outlet conditions:

          P_2 = 10 KPa       -------------> h_f = 191.81 KJ/kg

          x = 0.9                  -------------> h_fg = 2392.1 KJ/kg

          h_2 = h_f + x*h_fg

          h_2 = 191.81 + 0.9*2392.1 = 2344.7 KJ/kg

- The work produced by the turbine W_out is given by first Law of thermodynamics:

          W_out = flow(m) * ( h_1 - h_2 )

          flow ( m ) = W_out / ( h_1 - h_2 )

- Plug in values:

          flow ( m ) = 5*10^3 / ( 3375.1 - 2344.7 )

          flow ( m ) = 4.852 kg/s
