Answer:
The greatest gravitational potential energy is at apogee. The greatest kinetic energy is at perigee. Total Energy is constant.
Explanation:
The gravitational potential energy is at its greatest when the satellite is farthest from the earth, this point is called the apogee. And at this point the kinetic energy will be at its minimum.
The kinetic energy is greatest when the satellite is closest to the earth, this point is the perigee. And at this point the gravitational potential energy will be at a minimum level.
the total energy is the sum of the gravitational potential energy and the kinetic energy.As the satellite orbits the earth, the kinetic energy and the gravitational potential energymay be interchanged but the total energy will remain unchanged.
Answer:
job insecurity
Explanation:
I don't know can't remember
<span>On earth, the four major spheres interact as a system.
Atmosphere, biosphere, hydrosphere are absent.
Carbon, Oxygen cycle.
water circuit
tsunami (there is no water so no tsunami)
absence of life
there is no atmosphere so all meteorites directly interact with moon surface. On Earth they can be burn into the atmosphere due to the friction process</span>
Answer:
Explanation:
Oxygen is of no use to them, so they release it into the air. So there's a simple explanation for the Great Oxidation Event. It was the cyanobacteria, pumping out unwanted oxygen, that transformed Earth's atmosphere.
