Write a Python code to accept integer numbers in a list. Find and display the
sum and product of the numbers available at even and odd indices of the list,
respectively.

Answers

Answer 1

#initializing list

list1 = []

 

# accepting values from user

n = int(input("Enter number of elements in list: "))

 

# iterating till the range

for i in range(0, n):

   ele = int(input())

 

   list1.append(ele)

# sum and product at even and odd indexes

even_sum = 0

odd_sum = 0

even_prod = 1

odd_prod = 1

# iterating each element in list

for j in range(len(list1)):

   if j % 2 == 0:

       even_sum += list1[j]

       even_prod *= list1[j]

   else:

       odd_sum += list1[j]

       odd_prod *= list1[j]

# Displaying sum and product of even and odd indices

print("Sum of elements at even indices:", even_sum)

print("Product of elements at even indices:", even_prod)

print("Sum of elements at odd indices:", odd_sum)

The counterweight helps reduce the torque force on the mast is true.

What is meant by torque force?Torque is the rotating equivalent of force in physics and mechanics. The moment of force is another name for it. It illustrates how a force can cause a change in the body's rotational motion.The force that may twist an item about its axis is measured as torque. Torque is what causes an object to acquire angular acceleration, just as force is what causes an object to accelerate in linear kinematics. Being a vector quantity, torque. Torque is a twisting or turning force that frequently results in rotation around an axis, which may be a fixed point or the center of mass. A spinning object's capacity to overcome turning resistance, such as a gear or a shaft, is another way to conceptualize torque.

How will Hyperloop trains be different from traditional trains?

Answers

Answer:

Its passengers would sit comfortably in a pod while being propelled forward through a de-pressurized tube at 700 to 800 miles per hour (mph). The Hyperloop is afforded its super-fast travel speeds because of the tube, which allows the pod to travel through a virtually resistance-free track.

How do engineers deal with liquefaction when building a very tall building?

Answers

A structure that possesses ductility, has the ability to accommodate large deformations, adjustable supports for correction of differential settlements.

What is liquefaction?In reaction to an applied stress, such as the shaking during an earthquake or other fast change in stress state, a cohesionless saturated or partially saturated soil dramatically loses strength and stiffness, causing material that is typically a solid to behave like a liquid. When there is considerable ground shaking, loosely packed, water-logged sediments at or near the ground surface begin to liquefy. When there is considerable ground shaking, loosely packed, water-logged sediments at or near the ground surface begin to liquefy. During earthquakes, liquefaction that takes place beneath buildings and other structures can result in significant damage. Liquification is the physical conversion of a gas into a liquid state (condensation).

What is liquefaction How do you overcome it?

Liquefaction occurs when waterlogged, loosely packed sediments at or near the ground surface start to lose strength in reaction to violent ground shaking. Major damage during earthquakes can result from liquefaction that occurs beneath buildings and other structures.

Therefore, Water and loose sediments in your soil interact to cause the liquefaction process. In the end, this results in soil that is weaker than average and damages property. Avoiding construction in places that are liable to liquefaction is the best defense against it. Increase the foundation's strength and enhance the soil quality to reduce liquefaction.
