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

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.

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

What is the diode D forward or reverse biased?
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

What is the recommended method for harvesting leafy greens like lettuce and spinach?
Leafy greens like lettuce and spinach are harvested using the cut-and-come-again method. Outer leaves are carefully cut, leaving the inner ones to continue growing. This approach allows the plant to regenerate and provide multiple harvests, ensuring a sustainable yield. It also reduces waste, as onlRead more
Leafy greens like lettuce and spinach are harvested using the cut-and-come-again method. Outer leaves are carefully cut, leaving the inner ones to continue growing. This approach allows the plant to regenerate and provide multiple harvests, ensuring a sustainable yield. It also reduces waste, as only the needed leaves are harvested, maintaining the plant’s health and productivity.
See lessAt what temperature would an intrinsic semiconductor behave like a perfect insulator?
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/
