Answer:
Option A
Explanation:
A series of intermeshing gears is called a gear train.
Intermeshing gears turn in opposing directions.
In a gear train we have a gear known as the driver and one known as the follower.
Driver - is the gear that has the force or motion input.
Follower - is the gear that results in the force or motion output.
It may be noted that when the number of intermediate gears are odd, the motion of both the gears (i.e. driver and driven or follower) is in the same direction.
But if the number of intermediate gears are even, the motion of the driven or follower will be in the opposite direction of the driver
Answer:
The function in Python is as follows:
def unite_lists(A, B):
union = []
for elem in A:
if elem in B:
union.append(elem)
return union
Explanation:
This defines the function
def unite_lists(A, B):
This initializes an empty list for the union list
union = []
This iterates through list A
for elem in A:
This checks if the item in list A is in list B
if elem in B:
If it is present, the item is appended to the union list
union.append(elem)
This returns the union of the two lists
return union
