Answer:
False.
Explanation:
A stethoscope is a medical instrument which is used for listening to the work of the heart and lungs. It consists of a microphone that rests on the patient's chest, and rubber tubes that bring the sound to the earphones. An ordinary stethoscope does not have any moving or electrical parts, as it only mechanically conducts sound from the patient's chest to the doctor's ear. One of the simplest examinations that doctors perform today is listening to the lungs and heart with a stethoscope. With the help of this instrument, noises are heard during the work of the lungs and heart.

Answer:
In Python:
numberOfWholeSlices = int(22/7)
print(numberOfWholeSlices )
Explanation:
For each friend to get a whole number of slices, we need to make use of the int function to get the integer result when the number of slices is divided by the number of people.
So, the number of slice is: 22/7
In python, the expression when assigned to numberOfWholeSlices is:
numberOfWholeSlices = int(22/7)
Next, is to print the calculated number of slices
print(numberOfWholeSlices )
Answer:
The program to this question as follows:
Program:
def lettersOnly(s): #defining method lettersOnly
val="" #defining string variable that return value
for i in s: #defining loop to calculate value
if(i.isalpha()): #check condition that value is string
val=val+ i #add value
return val #return value
print(lettersOnly("data3base_ro1c3k5s")) #call method and print value
Output:
databaserocks
Explanation:
In the above python code, a method lettersOnly is declared that accepts a string variable "s" in its parameter. Inside the method, a string variable "val", and loop is declared, in which the "val" variable holds method return value.
- In the loop and if block is used that uses "isalpha" string method, which checks the check alphabetic character in the given value. if this is true it will calculate all value in "val" variable and return its value.
- At the last, the print method is used, which calls the lettersOnly method and prints its return value.
