The complete and the correct format for the question is as follows:
A 60 Hz three-phase 115kV transmission line has a series impedance of 30+j150 ohms/phase. The shunt susceptance of this line is 
The line to neutral voltages at buses p and q are and respectively. Compute , the three-phase real power losses in MW for this transmission circuit.
Answer:
0.183 MW
Explanation:
The diagrammatic illustration of the given information can be seen in the image attached below:
Thus: the current in the network can be computed as:
The 
can be computed as:
Finally; the three-phase real power loss is:
Answer:
The Net Present Worth at i 5% of Super Tools new test equipment is -$33,992.45
Explanation:
I calculated the net present based on cash flow projections that $300000 in years 1 and 2 ,declining by $50000 every year and it terminated year 8 with zero cash inflow.
I then discounted the cash flows using discounting factor calculated as (1+i)^n where i is the interest rate of 5% given as the n is the relevant year of cash flow.

Answer:
# string_contains function is defined with input_string
# as arguments
def string_contains(input_string):
# if-statement that check if letter z is in input_string
if 'z' in input_string:
# it print"has the letter z" if it has z
print("has the letter z")
else:
# else it print "not worthwhile"
print("not worthwhile")
# string_contains function is called
string_contains("The animal is zebra")
string_contains("learning is fun")
Explanation:
The code is written in Python and well commented.
Image of the output when the function is called is attached.
Answer:
c. avoid them by choosing not to drive if you expect severe weather
Answer:
The solution code is written in Python
- if(carYear < 1968):
- print("Probably has few safety features.\n")
-
- if(carYear > 1971):
- print("Probably has head rests\n")
-
- if(carYear > 1991):
- print("Probably has anti-lock brakes.\n")
-
- if(carYear > 2000):
- print("Probably has tire-pressure monitor.\n")
Explanation:
To create if statement, we just use the keyword "if" and joined with an operator either < (before) or > (after). Then we can use the print function to display the message based on the condition that met.
