Answer:
circumference of Nearth = 27692.30 km
Explanation:
we will apply here Eratosthenes logic that is here in this problem
near the sun is straight overhead at nyene and at same time that is ( 90-77 ) = 13° from zenith at the Alec town
and here 2 city 1000 km apart
so by Eratosthenes relation is
1000 =
× circumference of Nearth
circumference of Nearth = 1000 × 
circumference of Nearth = 27692.30 km

Answer:
Explanation:
Biomass refers to the organic matter from plants and animals.
It is also a source of renewable energy which can be used to produce electricity.
Energy from biomass orginates from the process of photosynthesis where green plants manufacture food for the ecosystem using carbon dioxide and sunlight.
Biomass has the following use:
It is widely available: Biomass can easily be sourced for. It is widely abundant in the environment.
It is inexpensive: Due to its wide availability, its source materials are very cheap and lies readily in the environment when we compare this to exploration for fossil fuels and mining for uranium.
It is carbon neutral: Since biomass constitutes a part of the carbon cycle, energy from biomass does not lead to climate change. Green plants use carbondioxide to manufacture their food and it is released back to the atmosphere when biomass is tapped.
It is environmentally friendly: The use of biomass as a source of energy does not affect the environment negatively. It is a clean source of energy.
It helps to reduce amount of waste: biomass energy helps us put wastes into a very good use.
