What is the value of acceleration due to gravity, g, 400 km above Earth’s surface, where the International Space Station is in orbit? [G = 6.67 × 10⁻¹¹ Nm²kg⁻², mass of Earth, M_E = 5.96 × 10²⁴ kg, radius of Earth, R_E = 6.37 × 10⁶ m]

Explanation

Saul (later Paul) persecuted Christians zealously. On the road to Damascus to arrest believers, a blinding light appeared. Jesus asked: “Saul, Saul, why do you persecute me?” (Acts 9)

Saul was blinded for three days, then Ananias was sent to restore his sight and baptize him. Saul immediately began preaching Jesus as the Christ, astonishing those who knew him as persecutor.

Pauls conversion demonstrates: no one is beyond Gods reach, grace transforms enemies into servants, and personal encounter with Christ changes everything. Paul became the apostle to the Gentiles.
