  1. Asked: January 20, 2025In: Class 12 Physics

    If both the number of protons and neutrons in a nuclear reaction is conserved, in what way is mass converted into energy (or vice versa)? Explain giving one example.

    In a nuclear reaction, mass can be converted into energy through the mass-energy equivalence principle, described by Einstein's equation E = mc² . While protons and neutrons are conserved, the total mass of the resulting particles can be slightly less than the initial mass. This "missing" mass is coRead more

    In a nuclear reaction, mass can be converted into energy through the mass-energy equivalence principle, described by Einstein’s equation
    E = mc²
    . While protons and neutrons are conserved, the total mass of the resulting particles can be slightly less than the initial mass. This “missing” mass is converted into energy. For example, in nuclear fusion, the mass of fused hydrogen atoms is slightly less than the combined mass of the individual atoms, and the difference is released as energy.

  2. Asked: January 21, 2025In: Class 12 Physics

    Name the type of biasing of a p-n junction diode so that the junction offers very high resistance.

    Shyam01 Sundar
    Added an answer on January 21, 2025 at 10:46 am

    The p-n junction diode offers very high resistance in reverse biasing, where the applied voltage increases the width of the depletion region, preventing the flow of majority charge carriers across the junction.

  3. Asked: January 21, 2025In: Class 12 Physics

    What is the diode D forward or reverse biased?

    Shyam01 Sundar
    Added an answer on January 21, 2025 at 10:46 am

    To determine if diode D is forward or reverse biased, check the voltage across it: Forward biased: Positive terminal of the battery connected to p-side. Reverse biased: Positive terminal connected to n-side. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-Read more

  4. Asked: January 21, 2025In: Class 12 Physics

    At what temperature would an intrinsic semiconductor behave like a perfect insulator?

    Shyam01 Sundar
    Added an answer on January 21, 2025 at 10:46 am

    An intrinsic semiconductor would behave like a perfect insulator at absolute zero temperature (0 Kelvin), as there would be no thermally excited electrons to conduct electricity. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-14/

  5. Asked: January 21, 2025In: Class 12 Physics

    What is the difference between an n-type and a p-type intrinsic semiconductor?

    Shyam01 Sundar
    Added an answer on January 21, 2025 at 9:50 am

    An n-type semiconductor is doped with elements like phosphorus, adding extra electrons (negative charge carriers). A p-type semiconductor is doped with elements like boron, creating "holes" (positive charge carriers) by missing electrons. Both enhance conductivity in intrinsic semiconductors but difRead more

    An n-type semiconductor is doped with elements like phosphorus, adding extra electrons (negative charge carriers). A p-type semiconductor is doped with elements like boron, creating “holes” (positive charge carriers) by missing electrons. Both enhance conductivity in intrinsic semiconductors but differ by dominant charge carriers: electrons in n-type and holes in p-type.
