Which of the following is NOT a fundamental force in physics?

  1. Gravitational Force

  2. Electromagnetic Force

  3. Strong Nuclear Force

  4. Frictional Force


Correct Option: D
Explanation:

Frictional force is not a fundamental force in physics. It is an emergent force that arises from the interaction of matter at the macroscopic level.

The chemical formula for water is:

  1. H2O

  2. CO2

  3. NaCl

  4. CH4


Correct Option: A
Explanation:

The chemical formula for water is H2O, indicating that a water molecule consists of two hydrogen atoms and one oxygen atom.

What is the derivative of (sin(x)) with respect to (x)?

  1. (cos(x))

  2. (sec(x))

  3. (-sin(x))

  4. (cosec(x))


Correct Option: A
Explanation:

The derivative of (sin(x)) with respect to (x) is (cos(x)).

Which of the following is NOT a greenhouse gas?

  1. Carbon Dioxide

  2. Methane

  3. Oxygen

  4. Water Vapor


Correct Option: C
Explanation:

Oxygen is not a greenhouse gas. Greenhouse gases are gases that trap heat in the Earth's atmosphere, contributing to global warming.

The SI unit of electric current is:

  1. Ampere

  2. Volt

  3. Ohm

  4. Coulomb


Correct Option: A
Explanation:

The SI unit of electric current is Ampere, which represents the flow of one coulomb of charge per second.

What is the formula for the area of a circle?

  1. (A = \pi r^2)

  2. (A = 2\pi r)

  3. (A = \pi d)

  4. (A = \frac{1}{2} \pi r^2)


Correct Option: A
Explanation:

The formula for the area of a circle is (A = \pi r^2), where (r) is the radius of the circle.

Which of the following is NOT a type of chemical bond?

  1. Covalent Bond

  2. Ionic Bond

  3. Metallic Bond

  4. Hydrogen Bond


Correct Option: C
Explanation:

Metallic bond is not a type of chemical bond. It is a type of physical bond that holds metal atoms together in a metallic lattice.

What is the chemical symbol for sodium?

  1. Na

  2. K

  3. Cl

  4. Ca


Correct Option: A
Explanation:

The chemical symbol for sodium is Na.

Which of the following is NOT a type of electromagnetic radiation?

  1. X-rays

  2. Gamma rays

  3. Ultraviolet rays

  4. Sound waves


Correct Option: D
Explanation:

Sound waves are not a type of electromagnetic radiation. They are mechanical waves that require a medium for propagation.

What is the formula for the volume of a sphere?

  1. (V = \frac{4}{3} \pi r^3)

  2. (V = \pi r^2)

  3. (V = 2\pi r)

  4. (V = \frac{1}{3} \pi r^2)


Correct Option: A
Explanation:

The formula for the volume of a sphere is (V = \frac{4}{3} \pi r^3), where (r) is the radius of the sphere.

Which of the following is NOT a law of thermodynamics?

  1. Zeroth Law of Thermodynamics

  2. First Law of Thermodynamics

  3. Second Law of Thermodynamics

  4. Third Law of Thermodynamics


Correct Option: A
Explanation:

The Zeroth Law of Thermodynamics is not a fundamental law of thermodynamics. It is a statement of thermal equilibrium, which states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.

What is the chemical formula for sulfuric acid?

  1. H2SO4

  2. HNO3

  3. HCl

  4. NaOH


Correct Option: A
Explanation:

The chemical formula for sulfuric acid is H2SO4.

Which of the following is NOT a type of conic section?

  1. Circle

  2. Ellipse

  3. Hyperbola

  4. Parabola


Correct Option: A
Explanation:

Circle is not a type of conic section. Conic sections are curves that are formed by the intersection of a plane and a cone.

What is the formula for the kinetic energy of an object?

  1. (KE = \frac{1}{2} mv^2)

  2. (KE = mv)

  3. (KE = \frac{1}{2} m^2v)

  4. (KE = \frac{1}{2} v^2)


Correct Option: A
Explanation:

The formula for the kinetic energy of an object is (KE = \frac{1}{2} mv^2), where (m) is the mass of the object and (v) is its velocity.

Which of the following is NOT a type of subatomic particle?
