About This Quiz

Physics as a subject covers different sub-fields There are two major divisions of physics namely; classical and modern Physics. Classical physics has further major sub-fields viz; mechanics, thermodynamics, acoustics, optics, electricity, and magnetism. The sub-fields of modern physics consist of chaos theory, relativity, string theory, cryogenics, crystallography, and nanotechnology. Do you know the formulas related to these sub-fields?

    P = mgh, what does P represent? - ProProfs

    P = mgh, what does P represent?

    • Pascal theory

    • Potential Energy

    • Kinetic energy

    • Gauss constant

    Correct Answer
    A. Potential Energy
    Explanation
    The equation P = mgh represents the potential energy of an object. Potential energy is the energy possessed by an object due to its position or state. In this equation, P represents the potential energy, m represents the mass of the object, g represents the acceleration due to gravity, and h represents the height or distance from a reference point. Therefore, the correct answer is Potential Energy.

    What does I represent in Ohm's law formula? - ProProfs

    What does I represent in Ohm's law formula?

    • Intent Heat

    • Doreen

    • Current

    • Power

    Correct Answer
    A. Current
    Explanation
    In Ohm's law formula, the letter "I" represents the current. Current is the flow of electric charge in a circuit, measured in amperes (A). Ohm's law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) across the conductor and inversely proportional to the resistance (R) of the conductor. Therefore, "I" represents the current in the formula.

    Which of these is Ohm's law formula? - ProProfs

    Which of these is Ohm's law formula?

    • I = V/R

    • V = s/t

    • I = V×R

    • R = I×V

    Correct Answer
    A. I = V/R
    Explanation
    Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. The formula I = V/R represents Ohm's law, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms. This formula shows that the current is equal to the voltage divided by the resistance.

    Calculate the buoyant force acting on it, if a stone of mass 250 g is thrown in water. Which formula is to be used to solve? - ProProfs

    Calculate the buoyant force acting on it, if a stone of mass 250 g is thrown in water. Which formula is to be used to solve?

    • F = u(v/t)

    • F = -ma

    • F = mg

    • F = mv²

    Correct Answer
    A. F = mg
    Explanation
    The formula to calculate the buoyant force acting on an object submerged in a fluid is F = mg. In this case, the stone is thrown in water, so we need to find the buoyant force. The buoyant force is equal to the weight of the fluid displaced by the stone, which is equal to the weight of the stone itself. Therefore, we can use the formula F = mg to calculate the buoyant force acting on the stone.

    What does ϕ represent in Q = ϕ ϵ0? - ProProfs

    What does ϕ represent in Q = ϕ ϵ0?

    • Ohm's constant

    • Artinian Ring

    • Total flux

    • Electric constant

    Correct Answer
    A. Total flux
    Explanation
    The symbol ϕ in the equation Q = ϕϵ0 represents the total flux. Flux is a measure of the flow of a physical quantity through a surface. In this context, it represents the total electric flux, which is the total amount of electric field passing through a given surface. The equation relates the electric charge (Q) to the electric flux (ϕ) and the electric constant (ϵ0), which is a fundamental constant in electromagnetism. Therefore, the correct answer is "Total flux."

    What formula is Q = ϕ ϵ0? - ProProfs

    What formula is Q = ϕ ϵ0?

    • Gauss formula

    • Holmes formula

    • Motion law

    • Quanta law of Physics

    Correct Answer
    A. Gauss formula
    Explanation
    The given correct answer for this question is "Gauss formula". The Gauss formula, represented as Q = ϕϵ0, is a mathematical equation derived from Gauss's law in electromagnetism. It relates the electric flux (ϕ) passing through a closed surface to the electric charge (Q) enclosed within that surface and the electric constant (ϵ0). This formula is used to calculate the electric field in various situations, such as when dealing with symmetric charge distributions or finding the electric field due to a point charge.

    A spring is stretched by 20 cm and has a force constant of 2 cm /dyne. Which of these formulas will solve this? - ProProfs

    A spring is stretched by 20 cm and has a force constant of 2 cm /dyne. Which of these formulas will solve this?

    • F = k + x

    • F = k x

    • F = – k x

    • F = k/x

    Correct Answer
    A. F = – k x
    Explanation
    The correct formula to solve this problem is F = -kx. This formula represents Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement of the spring from its equilibrium position. The negative sign indicates that the force is in the opposite direction of the displacement. The force constant, k, represents the stiffness of the spring and determines how much force is required to stretch or compress it. Multiplying the force constant by the displacement, x, gives the magnitude of the force exerted by the spring.

    Heat conduction Matter absorbs photon's energy and release heat into the surrounding. What is the formula for heat conduction? - ProProfs

    Heat conduction Matter absorbs photon's energy and release heat into the surrounding. What is the formula for heat conduction?

    • E = mC/∆t

    • E = m∆t/ C

    • E = C∆t/m

    • E = mC∆t

    Correct Answer
    A. E = mC∆t
    Explanation
    The formula for heat conduction is E = mC∆t. This formula represents the amount of heat energy (E) transferred through conduction, where m is the mass of the object, C is the specific heat capacity of the material, and ∆t is the change in temperature.

    Which of these is Newton's second formula for motion? - ProProfs

    Which of these is Newton's second formula for motion?

    • F = ma

    • S = ut + ½at²

    • V = s/t

    • V² = u² + at²

    Correct Answer
    A. S = ut + ½at²
    Explanation
    The formula S = ut + ½at² represents Newton's second formula for motion, also known as the equation for calculating displacement. It relates the initial velocity (u), time (t), acceleration (a), and displacement (S) of an object in motion. The equation takes into account both the initial velocity and the effect of acceleration over time, allowing us to calculate the total displacement of an object at a given time.
