The function below takes a single string parameter: input_string. If the input contains the lowercase letter z, return the strin
g 'has the letter z'. Otherwise, return the string 'not worthwhile'.
1 answer:
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:
capacity = 0.555 mAh
capacity = 3600 mAh
Explanation:
given data
battery = 1800 mAh
OCV = 3.9 V
solution
we get here capacity when it is in series
so here Q = 2C
capacity = 2 × ampere × second ...............1
put here value and we get
and 1 Ah = 3600 C
capacity =
capacity = 0.555 mAh
and
when it is in parallel than capacity will be
capacity = Q1 +Q2 ...............2
capacity = 1800 + 1800
capacity = 3600 mAh
Answer:
Diesel cycle:
All diesel engine works on diesel cycle.It have four processes .These four processes are as follows
1-2.Reversible adiabatic compression
2-3.Heat addition at constant pressure
3-4.Reversible adiabatic expansion
4-1.Heat addition at constant volume
When air inters in the piston cylinder after that it compresses and gets heated due to compression after that heat addition take place at constant pressure after that power is produces when piston moves to bottom dead center.
From the diagram of P-v And T-s we can understand so easily.
