If the temperature of the sun is doubled, the rate of energy received on earth will be increased by a factor of
The energy radiated by a body is given by Stefan-Boltzmann Law: E ∝ T⁴ Where: - E is the energy radiated, - T is the temperature in kelvins. If the temperature of the sun is doubled, i.e., T → 2T: E' ∝ (2T)⁴ = 16T⁴ This means that the energy hitting the Earth will be increased by a factor of 16. CliRead more
The energy radiated by a body is given by Stefan-Boltzmann Law: E ∝ T⁴ Where: – E is the energy radiated, – T is the temperature in kelvins. If the temperature of the sun is doubled, i.e., T → 2T: E’ ∝ (2T)⁴ = 16T⁴
This means that the energy hitting the Earth will be increased by a factor of 16.

What is biodiversity and what does it include?
Biodiversity refers to the diversity of life on Earth, encompassing plants, animals, birds, fish, insects, and microorganisms in ecosystems. It ensures ecological balance by supporting food chains, nutrient cycles, and habitat stability. This variety contributes to human well-being by providing resoRead more
Biodiversity refers to the diversity of life on Earth, encompassing plants, animals, birds, fish, insects, and microorganisms in ecosystems. It ensures ecological balance by supporting food chains, nutrient cycles, and habitat stability. This variety contributes to human well-being by providing resources like food, medicines, and ecosystem services. Biodiversity is found in all habitats, including forests, oceans, soil, and even urban areas.

The radiated energy by a black body follows the Stefan-Boltzmann law, according to which the energy radiated is proportional to the fourth power of the absolute temperature T (in Kelvin). Given temperature is 727°C. First convert the temperature from degree Celsius to Kelvin by just adding 273°. T =Read more
The radiated energy by a black body follows the Stefan-Boltzmann law, according to which the energy radiated is proportional to the fourth power of the absolute temperature T (in Kelvin).
Given temperature is 727°C. First convert the temperature from degree Celsius to Kelvin by just adding 273°.
T = 727°C + 273 = 1000 K
Since the radiated energy is proportional to T⁴, the energy in this case is proportional to (1000)⁴.

What information is included in a biodiversity register?
Biodiversity registers document the richness of life in an area. They include habitat characteristics, soil types, scientific and local names of species, their diets, pests, seasonal data, and interactions. The register also provides insights into medicinal plants, crop pests, and other species thatRead more
Biodiversity registers document the richness of life in an area. They include habitat characteristics, soil types, scientific and local names of species, their diets, pests, seasonal data, and interactions. The register also provides insights into medicinal plants, crop pests, and other species that influence agriculture or ecosystems. By maintaining this record, communities can safeguard local biodiversity, manage natural resources, and understand the ecological roles of various organisms.
See lessWhy is recording biodiversity important?
Biodiversity recording is essential to track species at risk due to habitat loss, agriculture, and climate changes. It helps identify endangered species, allowing targeted conservation. This process ensures ecosystem balance, as all species are interconnected and contribute to ecological stability.Read more
Biodiversity recording is essential to track species at risk due to habitat loss, agriculture, and climate changes. It helps identify endangered species, allowing targeted conservation. This process ensures ecosystem balance, as all species are interconnected and contribute to ecological stability. For humans, biodiversity supports food security, medicinal resources, and climate regulation. Documenting biodiversity is a step toward sustainable development and protecting the planet’s biological wealth.
