Explanation:
D:The source of cosmic background radiation filled the entire universe.
Answer: 3.63 km/s
Explanation:
The escape velocity equation for a craft launched from the Earth surface is:
Where:
is the escape velocity
is the Universal Gravitational constant
is the mass of the Earth
is the Earth's radius
However, in this situation the craft would be launched at a height
over the Eart's surface with a space elevator. Hence, we have to add this height to the equation:
Finally:
Answer:
law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.
