Share & grow the world's knowledge!
We want to connect the people who have knowledge to the people who need it, to bring together people with different perspectives so they can understand each other better, and to empower everyone to share their knowledge.
For measuring temperature in the range of 2,000 to 2,500°C, we should employ
Pyrometers are designed to measure extremely high temperatures, such as those in the range of 2,000 to 2,500°C, and are commonly used in industrial applications like furnaces and molten metal. Click here for more: https://www.tiwariacademy.com/ncert-solutions/class-11/physics/chapter-10/

Heat is flowing through the cylindrical rods of the same material. The diameter of the rods are in the ratio 1 : 2 and their lengths are in the ratio 2 : 1. If the temperature difference between their ends is the same, them the ratio of the amount of heat conducted through them per unit time will be
We apply the formula for heat conduction rate to solve this. Q = (kA(T₂ - T₁)) / L Q is the heat conducted per unit time k is the thermal conductivity A is the cross-sectional area (T₂ - T₁) is the temperature difference L is the length of the rod. We are given - The diameters are in the ratio 1:2,Read more
We apply the formula for heat conduction rate to solve this.
Q = (kA(T₂ – T₁)) / L
Q is the heat conducted per unit time
k is the thermal conductivity
A is the cross-sectional area
(T₂ – T₁) is the temperature difference
L is the length of the rod.
We are given
– The diameters are in the ratio 1:2, so the areas A will be in the ratio 1² : 2² = 1:4,
– The lengths are in the ratio 2:1.
We can now compute the ratio of heat conducted through the rods:
(Q₁ / Q₂) = (A₁ / L₁) × (L₂ / A₂) = (1 / 2) × (4 / 1) = 2
Thus, the ratio of heat conducted through the rods per unit time is 2:1.

What factors should be considered when selecting plants for a kitchen garden?
When selecting plants for a kitchen garden, prioritize those that thrive in your local climate and soil conditions. Choose fast-growing plants like coriander, spinach, or tomatoes for quick yields. Consider sunlight exposure, as some plants require full sun while others thrive in partial shade. OptRead more
When selecting plants for a kitchen garden, prioritize those that thrive in your local climate and soil conditions. Choose fast-growing plants like coriander, spinach, or tomatoes for quick yields. Consider sunlight exposure, as some plants require full sun while others thrive in partial shade. Opt for space-efficient plants that suit your garden size, and focus on herbs and vegetables your family frequently uses. Selecting compatible plants ensures better growth and a more productive kitchen garden.

Sunlight is crucial for photosynthesis, providing energy for plants to grow, flower, and produce fruits. Adequate sunlight exposure ensures strong and healthy plants. Spacing is equally important, as it prevents overcrowding, allowing each plant to receive sufficient sunlight, water, and nutrients.Read more
Sunlight is crucial for photosynthesis, providing energy for plants to grow, flower, and produce fruits. Adequate sunlight exposure ensures strong and healthy plants. Spacing is equally important, as it prevents overcrowding, allowing each plant to receive sufficient sunlight, water, and nutrients. Proper spacing improves air circulation, reducing the likelihood of fungal diseases. Together, sunlight and spacing are vital components in achieving optimal growth, ensuring the plants in a kitchen garden thrive and produce high-quality yields.

Healthy plant growth depends on several essential conditions. Adequate sunlight provides energy for photosynthesis, while water ensures hydration and nutrient transportation. Nutrient-rich soil enriched with organic manure or compost promotes root health. Proper spacing allows plants to grow without competition for sunlight, water, or nutrients. Additional factors, such as protection from pests, optimal temperature, and regular care through weeding and pruning, contribute significantly to achieving healthy and productive plants.
