What is Newton's second law of motion?
The acceleration of an object is constant regardless of the net force applied.
An object in motion will stay in motion unless acted upon by an equal force.
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).
The force acting on an object is equal to its mass times its velocity (F = mv).

Explain the principle of conservation of energy.
Energy can be created from nothing.
Energy cannot be created or destroyed, only transformed; total energy in a closed system remains constant.
Total energy in a closed system can increase over time.
Energy is only lost in transformations.

H2O
How do you create a list in Python?
my_list = {1, 2, 3}
my_list = [1, 2, 3]
my_list = '1, 2, 3'
my_list = (1, 2, 3)
Sanya is running in a park and checks her speed on a fitness tracker, which shows she is moving at a speed of 10 km/h. She also notes that she is running towards the north. What is the difference between speed and velocity?
Speed can be negative while velocity cannot.
Speed is always greater than velocity.
Velocity measures distance only, not direction.
Speed is scalar; velocity is vector (includes direction).
What is the pH scale and what does it measure?
The pH scale measures the temperature of a solution.
The pH scale measures the concentration of hydrogen ions in a solution.
The pH scale measures the density of a solution.
The pH scale indicates the color of a solution.
How do you handle exceptions in Python?
Use if-else statements to handle exceptions in Python.
Use try-except blocks to handle exceptions in Python.
Ignore exceptions and continue execution.
Use print statements to debug exceptions in Python.
How does the periodic table help in predicting the behavior of elements?
It provides a visual representation of chemical reactions.
It organizes elements according to their atomic mass.
It helps in understanding the trends in element properties and their reactivity.
It serves as a historical record of element discovery.
Dhruv is learning Python programming and comes across the 'def' keyword. What is the purpose of the 'def' keyword in Python?
To define a loop.
To define a class.
To define a function.
To define a variable.
What does the term 'kinetic energy' refer to in physics?
Energy possessed by an object due to its motion.
Energy stored in an object due to its position.
Energy that is lost during a reaction.
Energy that can be converted into heat.
What is the primary function of enzymes in biological systems?
To transport molecules across membranes.
To speed up chemical reactions.
To provide energy to cells.
To store genetic information.
What role do catalysts play in chemical reactions?
They change the products of the reaction.
They decrease the activation energy required for the reaction.
They increase the temperature of the reaction.
They are consumed during the reaction.
What is the law of universal gravitation?
Gravity increases with altitude.
Gravity is a force that only acts on Earth.
Gravity only affects objects with mass.
Every particle attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
What is the purpose of the 'import' statement in Python?
To create a new function.
To define a new variable.
To include external libraries or modules in a Python script.
To execute a script from the command line.
What is the function of the 'return' statement in a Python function?
To end the program.
To send a value back to the caller of the function.
To create a loop.
To define a new variable.
What is the role of a buffer in data processing?
To permanently store data.
To temporarily hold data while it is being moved from one place to another.
To encrypt data for security.
To compress data to save space.
What does the term 'reduction' refer to in chemistry?
The process of gaining electrons.
The process of losing electrons.
The process of forming a solid.
The process of combining compounds.

What is the role of chlorophyll in photosynthesis?
To transport nutrients throughout the plant.
To store water for the plant.
To provide structural support to plant cells.
To absorb sunlight and convert it into chemical energy.
What is the difference between an acid and a base?
Acids turn litmus paper blue, while bases turn it red.
Acids are always liquid, while bases are always solid.
Acids taste bitter, while bases taste sour.
Acids release hydrogen ions in solution, while bases release hydroxide ions.
What is the purpose of the 'while' loop in Python?
To import modules.
To execute a block of code repeatedly as long as a condition is true.
To define a function.
To create a new variable.
What is the significance of the atomic number in the periodic table?
It shows the reactivity of an element.
It determines the mass of an atom.
It represents the total number of protons in an atom.
It indicates the number of neutrons in an atom.
What is the purpose of the 'for' loop in Python?
To execute a block of code repeatedly for a specified number of times.
To define a function.
To create a new variable.
To import modules.
What is the significance of the law of conservation of mass in chemistry?
Mass can be created in chemical reactions.
Mass is conserved; the total mass of reactants equals the total mass of products.
Mass can be destroyed in chemical reactions.
Mass is irrelevant in chemical reactions.
What is the role of DNA in living organisms?
To catalyze biochemical reactions.
