Answer:
Explanation:
From the question we are told that:
Frequency selectivity ratio 
AM range 750 kHz to 2600 kHz
Therefore Bandwidth is
Generally the equation for The intermediate frequency is mathematically given by
Intermediate frequency=\frac{Bandwidth}{2}
Answer:
Explanation:
Given that:
Torque T = 2300 lb - ft
Bending moment M = 1500 lb - ft
axial thrust P = 2500 lb
yield points for tension σY= 100 ksi
yield points for shear τY = 50 ksi
Using maximum-shear-stress theory
where;
where;
Let say :
Then :
According to trial and error;
c = 0.75057 in
Replacing c into equation (1)
The required diameter d = 2c
d = 1.50 in or 0.125 ft
Answer:
# Program is written in python
# 22.1 Using the count method, find the number of occurrences of the character 's' in the string 'mississippi'.
# initializing string
Stringtocheck = "mississippi"
# using count() to get count of s
counter = Stringtocheck.count('s')
# printing result
print ("Count of s is : " + str(counter))
# 2.2 In the string 'mississippi', replace all occurrences of the substring 'iss' with 'ox
# Here, we'll make use of replace() method
# Prints the string by replacing iss by ox
print(Stringtocheck.replace("iss", "ox"))
#2.3 Find the index of the first occurrence of 'p' in 'mississippi'
# declare substring
substring = 'p'
# Find index
index = Stringtocheck.find(substring)
# Print index
print(index)
# End of program
Answer:
B. To accurately measure spark advance, use a timing light that incorporates an
ignition advance meter. The spark advance cannot be determined by listening to the way the engine sounds.
Answer:
c. an abrupt increase followed by a gradual decrease
Explanation:
