Why is Hohmann transfer most efficient? The most energy-efficient way to move between circular orbits is the Hohmann transfer orbit [1]. The first burst of thrust is calculated so that the maximum altitude of the resulting elliptical orbit is the desired altitude of the new circular orbit. Why is Hohmann transfer efficient? The Hohmann transfer […]

Why are producers the first organism in a food chain?
Why are producers the first organism in a food chain? Producers and consumers A food chain always starts with a producer , an organism that makes food. This is usually a green plant, because plants can make their own food by photosynthesis . The arrows in food chains show the way in which energy is […]

How does nuclear energy affect the environment?
How does nuclear energy affect the environment? Nuclear power plants use uranium as fuel. The process of mining uranium releases high amounts of carbon dioxide into the environment. Carbon dioxide is also released into the environment when new nuclear power plants are built. Finally, the transport of radioactive waste also causes carbon dioxide emissions. Which […]
Why do we replace orbits with orbitals?
Why do we replace orbits with orbitals? Heisenberg’s uncertainty principle replaced the concept of orbit by orbital because both position and momentum can be calculated in the orbit of electron, which is impossible. The new changed model of atom was called wave mechanical model of atom. What do orbits and orbitals have in common? Answer: […]
What is the electromagnetic spectrum simple definition?
What is the electromagnetic spectrum simple definition? Electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. The electromagnetic spectrum comprises the span of all electromagnetic radiation and consists of many subranges, commonly referred to as portions, such as visible light or ultraviolet radiation. What is the electromagnetic spectrum and why is […]
