    What is the main energy transformation in a battery-operated flashlight?

    • Mechanical to Electrical

    • Chemical to Electrical

    • Nuclear to Electrical

    • Solar to Electrical

    Correct Answer
    A. Chemical to Electrical
    Explanation
    In a battery-operated flashlight, the main energy transformation is from chemical to electrical energy. The battery contains chemicals that undergo reactions to produce electricity. This electrical energy is then used to power the flashlight's bulb, converting it further into light (and some thermal) energy, illuminating the surroundings.

    What is the unit of force in the International System of Units?

    • Joule

    • Newton

    • Pascal

    • Watt

    Correct Answer
    A. Newton
    Explanation
    The correct unit of force in the International System of Units is the Newton. This unit measures the amount of force required to accelerate a mass of one kilogram at a rate of one meter per second squared. Named after Sir Isaac Newton, it quantifies the influence that results in the acceleration of an object, reflecting Newton's second law of motion, F=ma, where F is force, m is mass, and a is acceleration.

    What does the slope of a distance-time graph represent?

    • Acceleration

    • Velocity

    • Time

    • Distance

    Correct Answer
    A. Velocity
    Explanation
    The slope of a distance-time graph represents velocity. This graph plots distance on the vertical axis against time on the horizontal axis. A steeper slope indicates a higher velocity, showing that the object is covering more distance in less time. Conversely, a flatter slope indicates a slower velocity. This graphical representation helps visually demonstrate how the speed of an object changes over time.

    What type of circuit allows current to flow through multiple paths?

    • Series circuit

    • Parallel circuit

    • Closed circuit

    • Integrated circuit

    Correct Answer
    A. Parallel circuit
    Explanation
    A parallel circuit allows electrical current to flow through multiple paths. Unlike a series circuit where the current has only one path, in a parallel circuit, each component is connected across the same set of electrically common points, creating branches. Each branch in a parallel circuit has a direct route to the power source, which ensures that if one path is interrupted, current can still flow through other paths.

    Which law states that every action has an equal and opposite reaction?

    • First law of motion

    • Second law of motion

    • Third law of motion

    • Law of conservation of energy

    Correct Answer
    A. Third law of motion
    Explanation
    Newton's third law of motion states that for every action, there is an equal and opposite reaction. This fundamental principle of physics explains how forces are interactions between two objects: whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. This law is crucial in studying motion and is observable in everyday phenomena, such as the recoil of a gun or the propulsion of a jet.

    In which scenario is potential energy converted into kinetic energy?

    • Compressing a spring

    • A car accelerating

    • A ball thrown upwards

    • A falling apple

    Correct Answer
    A. A falling apple
    Explanation
    Potential energy is converted into kinetic energy when an object moves from a state of being stationary to motion, such as a falling apple. Initially, the apple held at a height possesses gravitational potential energy due to its position. As it falls, this potential energy is converted into kinetic energy, increasing as the apple accelerates towards the ground due to gravity.

    What device is used to measure electric current?

    • Voltmeter

    • Ammeter

    • Galvanometer

    • Barometer

    Correct Answer
    A. Ammeter
    Explanation
    An ammeter is used to measure electric current. It is connected in series within a circuit to ensure that all electrons flowing through the circuit also pass through the ammeter. This device is calibrated to measure the intensity of the current, which is the rate of flow of electric charge, helping in diagnostics and circuit analysis in physics and engineering applications.

    How is the period of a pendulum affected by increasing the length of the string?

    • The period decreases

    • The period increases

    • The period stays the same

    • The period doubles

    Correct Answer
    A. The period increases
    Explanation
    Increasing the length of the string in a pendulum increases its period, which is the time it takes for one complete oscillation. The period of a pendulum is given by T = 2π(sqrt(L/g)), where L is the length of the pendulum and g is the acceleration due to gravity. A longer string means a longer period, making the pendulum swing slower. This relationship shows that the pendulum's swinging motion becomes more prolonged as the string lengthens, due to the increased distance the pendulum must travel in each swing, thus directly impacting its oscillation rate.

    Which phenomenon demonstrates the wave nature of light?

    • Reflection

    • Refraction

    • Diffraction

    • Polarization

    Correct Answer
    A. Diffraction
    Explanation
    Diffraction demonstrates the wave nature of light. This phenomenon occurs when a wave encounters an obstacle or a slit that is comparable in size to its wavelength and bends around it. Diffraction is significant evidence of light’s wave properties, differentiating it from purely particle behavior, and is critical in understanding wave optics.
