The correct answer is (D) Ambiguity problem for context free grammar. The phrase "We saw her duck" is a paraphrase of the lines "We saw her drop her head" and "We saw the duck that belonged to her,".
An ambiguous grammar is one in which there is more than one derivation tree for a given string w L(G). There are several left- or right-most derivations for a given string produced by that grammar. Grammar that is unclear: A CFG is said to be unclear if more than one LeftMost Derivation Tree (LMDT) or RightMost Derivation Tree exists for the given input text (RMDT). Any CFG that has numerous leftmost derivations from the start symbol for one or more terminal strings is considered ambiguous. Alternatively, different rightmost derivations or different parse trees.

A simple machine increases the distance that a force needs to be applied from 3 meters to 27 meters, and the work done is 216 joules. How much force is applied?.
The work done is 216 joules, and a simple machine extends the distance over which a force must be exerted from 3 meters to 27 meters. The applied force is 8N.
By shifting the direction in which the force must be applied, the output force can be divided by the input force. 3N W=△E 8N
A physical system known as a machine uses power to apply forces, regulate movement, and carry out an action. In addition to naturally occurring biological macromolecules like molecular machines, the phrase is frequently used to describe artificial devices that use engines or motors. Machines can be propelled by humans, animals, and natural forces like wind and water. They can also be propelled by chemical, thermal, or electrical energy. These machines typically have a system of mechanisms that shape the actuator input to produce a particular application of output forces and movement. They can also contain mechanical systems, which are generally referred to as computers and sensors that track performance and coordinate movement.
The six basic mechanisms that move a load were named by Renaissance natural philosophers as simple machines.

Below is an example of how you can write a loop in Python to print the words that start with "F" or "L" from the list w:
w = ["Algorithm", "Logic", "Filter", "Software", "Network", "Parameters", "Analyze", "Algorithm", "Functionality", "Viruses"]
for word in w:
if word[0] == "F" or word[0] == "L":
print(word)
The output of this code will be:
Logic
Filter
Functionality
What is the Programming language about?The above code uses a for loop to iterate through the list of words w. The for loop starts with the line for word in w:. This line tells the loop to assign each element of the list w to the variable word in turn and execute the indented code block for each value.
The indented code block that follows the for loop starts with an if statement if word[0] == "F" or word[0] == "L":. This line checks if the first letter of the word stored in the variable word is "F" or "L". The square brackets [] after the variable name word are used to access an element in a list or a string.
Here word[0] is used to access the first letter of the word, since indexing in python starts from 0. The or operator is used to check if either the first letter is F or the first letter is L.
If the condition in the if statement is true, the code indented under the if statement is executed. In this case, the word is printed using the print() function. This will print all the words that starts with "F" or "L" from the list w.

b. A Java GC process is responsible to take care of heap memory and deallocate the space occupied by those objects no longer used.
c. The Java memory management API allows developers to write code directly deallocating the used memory space.
d. JDK offers an interface for Java developers to use in managing the memory heap, e.g. deallocate the memory after a given period of time.
The statement about java that's true is b. A Java GC process is responsible to take care of heap memory and deallocate the space occupied by those objects no longer used. In Java, the JVM (Java Virtual Machine) handles memory management by using a process called Garbage Collection (GC).
The GC process is responsible for identifying and freeing up memory that is no longer being used by the application. This process occurs automatically and in the background, without the need for developers to explicitly create a new thread or write code to deallocate memory. The JDK (Java Development Kit) also provides an interface for developers to use in managing the heap memory, but this is not used for deallocating memory. Instead, it can be used for monitoring and tuning the performance of the GC process.
