A 1.00-m2 solar panel on a satellite that keeps the panel oriented perpendicular to radiation arriving from the Sun absorbs 1.40 kJ of energy every second. The satellite is located at 1.00 AU from the Sun. (The Earth-Sun distance is approximately 1.00 AU.) How long would it take an identical panel that is also oriented perpendicular to the incoming radiation to absorb the same amount of energy, if it were on an interplanetary exploration vehicle 2.05 AU from the Sun? answer in seconds
