Answer:
Insert
'try:' at line 1
'except:' at line 3
Explanation:
The "try and except" commands in Python are used for exception handling.
try: the statements under this block are executed normally
except: the the statements under this block are executed when there is an exception.
We can use these commands to handle errors, for example, in the given scenario we don't want the user to enter a floating point number such as
1.5, 2.6 etc.
When the user enters an integer number then the except command is not executed.
When the user enters a floating point number then the except command is executed, program is stopped and error message is shown that is at line 4
Python code:
# line 1
try:
# line 2
age = int(input("Enter your age: "))
# line 3
except:
# line 4
print("Invalid input")
Output:
Test 1:
Enter your age: 20
Test 2:
Enter your age: 20.5
Invalid input

Explanation:
Advantages of liquid electrical tape over conventional electrical tape for covering exposed conductors is given below.
Explanation:
- Electrical tape and "regular" adhesive tape is that electrical tape is stretchy. This allows the tape to wrap around a wire junction and still grab the insulation to either side. This helps keep the tape in place.Where as Regular tape is likely to get stiff, lose adhesion, and slide away from the joint, leaving it exposed.
- The electrical tape is able to withstand much more heat and like the others said the adhesive is better and it can stretch 200 percent.
- Electrical tape is a suitable long-term or permanent solution in various applications.Heat-shrink sleeving, spiral wrap, flexible conduit, self-amalgamating tape, rubber sleeves, junction boxes, table ties/clips, grommets, cable markers, etc. are all better solutions for almost any given use of electrical tape other than to conventional electrical tape which has temporarily hold, bundle, insulate, or mark a cable.
- This kind of type is often used by electricians. It's typically made of slightly stretchy PVC vinyl, and is backed with a pressure sensitive rubber-type adhesive. It has good insulative properties, and is perfect for protecting wire splices and providing extra insulation on electrical cords. it's also available in a variety of other colors (like red, green, yellow, green, and white) that can be used for color-coding.
Answer:
%Reduction in area = 73.41%
%Reduction in elongation = 42.20%
Explanation:
Given
Original diameter = 12.8 mm
Gauge length = 50.80mm
Diameter at the point of fracture = 6.60 mm (0.260 in.)
Fractured gauge length = 72.14 mm.
%Reduction in Area is given as:
((do/2)² - (d1/2)²)/(do/2)²
Calculating percent reduction in area
do = 12.8mm, d1 = 6.6mm
So,
%RA = ((12.8/2)² - 6.6/2)²)/(12.8/2)²
%RA = 0.734130859375
%RA = 73.41%
Calculating percent reduction in elongation
%Reduction in elongation is given as:
((do) - (d1))/(d1)
do = 72.14mm, d1 = 50.80mm
So,
%RA = ((72.24) - (50.80))/(50.80)
%RA = 0.422047244094488
%RA = 42.20%
