To find the orbital velocity of a planet, you will need to use the following equation: orbital velocity = sqrt(GM/r), where G is the universal gravitational constant, M is the mass of the planet, and r is the planet's mean orbital radius.

1. Navigation: GPS satellites can pinpoint exact locations to a very high degree of accuracy. This allows military personnel to navigate accurate routes to their objectives and avoid dangers. 2. Surveillance: GPS receivers can track moving objects, allowing military personnel to better monitor the whereabouts of enemy forces and observe their movements. 3. Missile Guidance: GPS satellites can provide highly accurate guidance information to military weapon systems, helping to ensure precision strikes on target. 4. Artillery: GPS enabled precision-guided munitions can accurately target enemy positions and structures. 5. Reconnaissance: Military personnel can make use of GPS when conducting reconnaissance missions to gather intelligence on enemy movements and activities. 6. Air Traffic Control: GPS provides air traffic controllers with real-time tracking information on military aircraft. This helps to ensure safe and efficient air travel.

Early Christians spread their faith primarily through word of mouth, through small house-based meetings and by travelling between cities, both within Roman Empire and across the whole Mediterranean region. Other methods were also used to spread Christianity, such as literature, iconography and other forms of visual art, and artwork depicting religious scenes which were distributed from the Church. In addition to this, due to the changing political climate across the region, other concessions were also made to allow Christians to preach and spread the faith.
