  1. 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

    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.

    Several factors influence watering needs: plant species, soil type, weather, and plant growth stage. Sandy soil drains water quickly, requiring frequent irrigation, while clay retains moisture longer. Young plants need more frequent watering than mature ones. Hot, dry weather increases water demand, whereas cooler, humid conditions reduce it. Additionally, large leafy plants lose more water through transpiration. Understanding these factors ensures plants receive appropriate hydration for optimal growth.

    Watering plants in the early morning or late afternoon is ideal. During these times, temperatures are cooler, and water loss due to evaporation is reduced. Early watering helps plants absorb moisture before the sun intensifies, while late afternoon watering replenishes lost water without prolonged wetness overnight. Both timings ensure plants receive adequate hydration, supporting healthy growth and reducing stress. Proper timing also helps conserve water by minimizing wastage.
