Question: What is the difference between a function and a relation?
Answer: A relation is a set of ordered pairs, while a function is a relation in which each input (x) has exactly one output (y).
Question: What is the solution of the linear equation 2x + 3 = 7?
Answer: The solution is x = 2.
Question: How do you solve a system of linear equations?
Answer: A system of linear equations can be solved by substitution or elimination method.
Question: What are the properties of a matrix?
Answer: The properties of a matrix include order, determinants, inverse, and rank.
Question: What is the Pythagorean theorem?
Answer: The Pythagorean theorem states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Question: What is the concept of inverse of a matrix?
Answer: The inverse of a matrix is another matrix that, when multiplied with the original matrix, results in the identity matrix.
Question: What is the difference between permutations and combinations?
Answer: Permutations refer to the arrangement of objects, while combinations refer to the selection of objects without considering the order.
Question: What is the binomial theorem?
Answer: The binomial theorem describes the algebraic expansion of powers of a binomial expression.
Question: How do you find the area of a circle?
Answer: The area of a circle is given by the formula:
Area = π * r², where r is the radius of the circle.
Question: Define an arithmetic progression.
Answer: An arithmetic progression is a sequence of numbers in which the difference between consecutive terms is constant.
Question: What is the sum of the first n terms of an arithmetic series?
Answer: The sum of the first n terms is given by the formula:
Sₙ = n/2 * (2a + (n-1)d), where a is the first term and d is the common difference.
Question: What is the principle of mathematical induction?
Answer: The principle of mathematical induction is used to prove that a statement is true for all natural numbers.
Question: What are the properties of determinants?
Answer: Some properties of determinants include the determinant of a triangular matrix being the product of its diagonal elements, and the determinant of a matrix being zero if its rows or columns are linearly dependent.
Question: How do you calculate the distance between two points in a plane?
Answer: The distance between two points (x₁, y₁) and (x₂, y₂) is given by the formula:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²].
Question: What is the concept of logarithms?
Answer: A logarithm is the inverse operation of exponentiation. For example, logₐ b = c means aᶜ = b.
Question: Define the term 'binomial coefficient.'
Answer: The binomial coefficient represents the number of ways to choose a subset of elements from a larger set, often written as "n choose k."
Question: What is a geometric progression?
Answer: A geometric progression is a sequence of numbers where each term after the first is found by multiplying the previous term by a constant.
Question: How do you find the median of a data set?
Answer: The median is the middle value in a data set when the values are arranged in ascending or descending order.
Physics
Question: What is Newton’s First Law of Motion?
Answer: Newton's First Law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.
Question: Define velocity.
Answer: Velocity is the rate of change of displacement of an object with respect to time, including direction.
Question: What is the formula for calculating force?
Answer: Force is calculated using the formula:
Force = mass * acceleration.
Question: What is the law of conservation of energy?
Answer: The law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.
Question: What is the difference between speed and velocity?
Answer: Speed is the distance traveled per unit of time, while velocity is speed with a specified direction.
Question: Define work done in physics.
Answer: Work done is the product of force and the displacement of the object in the direction of the force.
Question: What is the unit of power?
Answer: The unit of power is the watt (W), which is equivalent to one joule per second.
Question: What is gravitational force?
Answer: Gravitational force is the force of attraction between two masses. It depends on the masses and the distance between them.
Question: Define kinetic energy.
Answer: Kinetic energy is the energy possessed by an object due to its motion, given by the formula:
Kinetic Energy = 1/2 * m * v².
Question: What is potential energy?
Answer: Potential energy is the energy possessed by an object due to its position in a force field, such as gravitational or elastic potential energy.
Question: What is the formula for calculating pressure?
Answer: Pressure is calculated using the formula:
Pressure = Force / Area.
Question: What is the principle of conservation of momentum?
Answer: The principle of conservation of momentum states that the total momentum of a system remains constant if no external forces act on it.
Question: What is Hooke's Law?
Answer: Hooke's Law states that the force required to extend or compress a spring is directly proportional to the displacement from its equilibrium position.
Question: What is the difference between scalar and vector quantities?
Answer: Scalar quantities have only magnitude, while vector quantities have both magnitude and direction.
Question: Define acceleration.
Answer: Acceleration is the rate of change of velocity of an object with respect to time.
Question: What is Ohm’s Law?
Answer: Ohm's Law states that the current through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance.
Question: What is the formula for calculating the wavelength of a wave?
Answer: The wavelength is calculated using the formula:
Wavelength = Speed of Wave / Frequency.
Question: What is a simple harmonic motion?
Answer: Simple harmonic motion is the repetitive back-and-forth movement of an object around a central equilibrium position.
Question: What is the difference between heat and temperature?
Answer: Heat is the energy transferred between objects due to a temperature difference, while temperature is the measure of the average kinetic energy of particles in a substance.
Question: Define electrostatic force.
Answer: Electrostatic force is the force of attraction or repulsion between two charged objects.
Question: What is the formula for the Coulomb's Law?
Answer: Coulomb's Law is given by the formula:
F = k * (q₁ * q₂) / r², where k is the electrostatic constant, q₁ and q₂ are the charges, and r is the distance between the charges.
