    What does AC and DC stand for in the electrical field?

    • Alternating Current and Direct Current

    • A Rock Band from Australia

    • Average Current and Discharged Capacitor

    • Atlantic City and District of Columbia

    Correct Answer
    A. Alternating Current and Direct Current
    Explanation
    AC and DC stand for Alternating Current and Direct Current in the electrical field. Alternating Current refers to the flow of electric charge that periodically reverses direction, commonly used in household electricity. Direct Current, on the other hand, refers to the flow of electric charge in only one direction, commonly used in batteries and electronic devices.

    Deficiency of which Vitamin can cause Scurvy ?

    • Vitamin A

    • Vitamin B

    • Vitamin C

    • Vitamin D

    Correct Answer
    A. Vitamin C
    Explanation
    Deficiency of Vitamin C can cause scurvy. Scurvy is a disease characterized by weakness, anemia, gum disease, and skin hemorrhages. Vitamin C is essential for the synthesis of collagen, a protein that helps in the formation of connective tissues, blood vessels, and wound healing. Without enough Vitamin C, the body is unable to produce collagen, leading to the breakdown of connective tissues and the symptoms of scurvy. Vitamin A, Vitamin B, and Vitamin D deficiencies do not cause scurvy.

    Araneology is the branch of science deals in?

    • The study of spiders

    • The study of lizards

    • The study of tigers

    Correct Answer
    A. The study of spiders
    Explanation
    Araneology is the branch of science that deals with the study of spiders. This field focuses on various aspects of spiders, including their taxonomy, anatomy, behavior, ecology, and evolution. Araneologists study different species of spiders, their habitats, feeding habits, reproduction, and their role in ecosystems. They also investigate the venom and silk production of spiders, as well as their interactions with other organisms. By understanding spiders, araneologists contribute to our knowledge of biodiversity, ecological relationships, and the development of potential applications in medicine and technology.

    What was the active medium used in the first working laser ever constructed?

    • A diamond block

    • Helium-neon gas

    • A ruby rod

    • Carbon dioxide gas

    Correct Answer
    A. A ruby rod
    Explanation
    The first working laser ever constructed used a ruby rod as its active medium. The ruby rod is a cylindrical piece of synthetic ruby that is doped with chromium ions. When energy is applied to the ruby rod, the chromium ions become excited and emit light. This light then bounces back and forth within the rod, reflecting off the ends, and amplifying to create a coherent beam of laser light. The use of a ruby rod as the active medium allowed for the production of a focused and intense laser beam.
