Answer:
B. PEi + KEi = PEf + KEf
Explanation:
It is given that
A leaf falling to the ground before hitting the ground has an initial total energy of PEi + KEi.
And the total final energy of the leaf after it hits the ground is PEf + KEf .
Since there is no air resistance, therefore the total energy is conserved.
According to the conservation of law of conservation of energy, energy is neither created nor it is destroyed. The energy is always conserved. The initial energy will be equal to the final energy.
Thus the total energy of the leaf before hitting the ground and after hitting the ground will be equal.
Thus initial energy is equal to the final energy.
Hence the answer is ---
B. PEi + KEi = PEf + KEf
Answer:
According to the Virginia Plan, states with a large population would have more representatives than smaller states. Large states supported this plan, while smaller states generally opposed it. Under the New Jersey Plan, the unicameral legislature with one vote per state was inherited from the Articles of Confederation.

In Python programming, to assign a string literal to a variable, the string value must be enclosed in quotation marks: True.
<h3>What is Python?</h3>
Python can be defined as a high-level programming language that is designed and developed to build websites and software applications, especially through the use of dynamic commands (semantics) and data structures.
<h3>What is a variable?</h3>
A variable can be defined as a specific name which refers to a location in computer memory and it is typically used for storing a value such as an integer or string.
In Python programming, it is very true that for a programmer to assign a string literal to a variable, the string value must be enclosed in quotation marks. For example, print "welcome"
