Answer:
The power developed by engine is 167.55 KW
Explanation:
Given that

Mean effective pressure = 6.4 bar
Speed = 2000 rpm
We know that power is the work done per second.
So

We have to notice one point that we divide by 120 instead of 60, because it is a 4 cylinder engine.
P=167.55 KW
So the power developed by engine is 167.55 KW
Answer:
a) zero b) zero
Explanation:
Newton's first law tells us that a body remains at rest or in uniform rectilinear motion, if a net force is not applied on it, that is, if there are no applied forces or If the sum of forces acting is zero. In this case there is a body that moves with uniform rectilinear motion which implies that there is no net force.
Answer:
def extract_word_with_given_letter(sentence, letter):
words = sentence.split()
for word in words:
if letter in word.lower():
return word
return ""
# Testing the function here. ignore/remove the code below if not required
print(extract_word_with_given_letter('hello HOW are you?', 'w'))
print(extract_word_with_given_letter('hello how are you?', 'w'))
