What precautions you took to avoid damaging the plants while harvesting?
To prevent damage while harvesting, we ensured tools like shears and trowels were clean and sharp to reduce the risk of infection and ensure precise cuts. Plants were handled with care, avoiding rough pulling or tugging that could harm roots or stems. Harvesting was done at the correct maturity stagRead more
To prevent damage while harvesting, we ensured tools like shears and trowels were clean and sharp to reduce the risk of infection and ensure precise cuts. Plants were handled with care, avoiding rough pulling or tugging that could harm roots or stems. Harvesting was done at the correct maturity stage, ensuring the produce was ripe but the plant remained undisturbed for further growth. Wearing gloves also minimized unintentional bruising of leaves or fruits.

The angular momentum of an electron in the second excited state (n=3) of a hydrogen atom, according to Bohr's model, is given by L = nℏ, where n = 3. Thus, L = 3ℏ. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-12/

According to kinetic theory of gases at absolute zero of temperature
According to the kinetic theory of gases, at absolute zero (0 Kelvin or -273.15°C), the molecules of a substance have no kinetic energy and their motion theoretically stops completely. This is the lowest possible temperature. Click this more information: https://www.tiwariacademy.com/ncert-solutionsRead more

Mercury thermometer can be used to measure temperature upto
Mercury thermometers can measure temperatures up to around 360°C because mercury stays in its liquid state up to this temperature. Beyond this, mercury begins to vaporize and cannot be used for measurements above this point. Click for more: https://www.tiwariacademy.com/ncert-solutions/class-11/physRead more

If the temperature of the sun were to increase from T to 2 T and its radius from R to 2 R, then the ratio of the radiant energy received on earth to what it was previously, will be
The amount of sun's radiant energy received is proportional to the power output of the sun from Stefan-Boltzmann's Law: P ∝ R²T⁴ 1. Preliminary P₁ ∝ R²T⁴ 2. After alteration - The radius increases to 2R: The area increases proportionally to (2R)² = 4R² - Temperature increases to 2T: Power increasesRead more
The amount of sun’s radiant energy received is proportional to the power output of the sun from Stefan-Boltzmann’s Law:
P ∝ R²T⁴
1. Preliminary
P₁ ∝ R²T⁴
2. After alteration
– The radius increases to 2R: The area increases proportionally to (2R)² = 4R²
– Temperature increases to 2T: Power increases proportionally to (2T)⁴ = 16T⁴
– Total power increases to:
P₂ ∝ 4R² × 16T⁴ = 64R²T⁴
3. The ratio of the new power to the old power:
P₂ / P₁ = (64R²T⁴) / (R²T⁴) = 64
Thus, the radiant energy received on Earth will increase by a factor of 64.
