Answer:
Explanation:
For a satellite in orbit around a planet, the gravitational force between the planet and the satellite is equal to the centripetal force that keeps the satellite in circular motion.
So, we can write:
where
G is the gravitational constant
M is the mass of the planet
m is the mass of the satellite
r is the orbital radius of the satellite
v is the speed of the satellite
The equation can be rewritten as
Also, we can write the orbital speed as the ratio between the length of the orbit (circumference of the orbit) and orbital period, T:
Substituting into the equation for M,
Here we have:
is the orbital radius
is the orbital period
Substituting, we find the mass of the Saturn:
Liquid water is not a mineral
Answer:
Physical Maps
Explanation:
Physical maps show the physical outlay of a specific geographic area.
The naval strategy is the preparation and execution of combat at sea. Naval strategy and the associated theory of maritime strategy involves the comprehensive strategy for gaining supremacy at sea, which includes the planning and execution of operations, the action and disposition of naval units by which a leader achieves the benefit of struggling at a place accessible to himself, and the deception of the opponent. The following are the fundamental functions of the U.S. Navy, Marine Corps, and Coast Guard in the execution of the National Naval Strategy:
1. Secure strategic passage and maintain the global choice of action.
2. Extend existing and developing partnerships and alliances
3. Secure favorable defense requirements
4. guard the U.S. against direct invasion
