Answer:

386.2^{\circ}F

Explanation:

We are given that

P_1=200lbf/in^2

P_2=60lbf/in^2

v_1=200ft/s

v_2=1700ft/s

T_1=500^{\circ}F

Q=0

C_p=1BTU/lb^{\circ}F

We have to find the exit temperature.

By steady energy flow equation

h_1+v^2_1+Q=h_2+v^2_2

C_pT_1+\frac{P^2_1}{25037}+Q=C_pT_2+\frac{P^2_2}{25037}

1BTU/lb=25037ft^2/s^2

Substitute the values

1\times 500+\frac{(200)^2}{25037}+0=1\times T_2+\frac{(1700)^2}{25037}

500+1.598=T_2+115.4

T_2=500+1.598-115.4

T_2=386.2^{\circ}F

Explanation:

The limitation of the current Internet are as follows

1.The speed of the internet.When the number of user used the same internet then the speed of the internet decrease.

2.The band with is limited.

3.Continued reliance on cables and wires for connectivity

So the option d is correct.

As a therapist who specializes in dreams, I would interpret Justina’s dream by using: 17. Freud’s wish-fulfilling theory.

<h3>Who is Sigmund Freud?</h3>

Sigmund Freud was an Austrian physiologist, neurologist, medical doctor and the founder of psychoanalysis. Also, Freud was born in Moravia on the 6th of May, 1856 and he was famously known around the world for his works on psychoanalytic theory of personality development.

In 1923, Sigmund Freud developed the personality theory through which he strongly argued that a person’s personality (human psyche) is structured into three (3) key parts and these include:

  • The Id (instincts).
  • Ego (reality).
  • Superego (morality).

According to Sigmund Freud, wish fulfillment simply means the satisfaction of a human desire through an involuntary thought process such as dreams. Thus, it typically happens to a person when unconscious desires are adequately repressed by both the ego and superego.
