• find the time period of revolution? The time period of the revolution is calculated by dividing the circumference of the orbit by the speed. Circumference of Orbit = 2 * π * Radius Radius = Distance from Centre of Earth to Satellite Time Period = (2 * π * Radius) / Speed Time Period = (2 * 3.14 * 6,371,000 m) / 4,000 m/s Time Period = 758.8 seconds ≈ 12.6 minutes

• calculate its centripetal acceleration Centripetal acceleration can be calculated using the formula a = v2/r, where a is the centripetal acceleration, v is the velocity of the satellite, and r is the radius of the orbit. In this case, since the velocity of the satellite is 4000 m/s, and we assume it is orbiting at a radius of 1 m, the centripetal acceleration is 16,000,000 m/s2.
