When a satellite in a circular orbit around the earth enters the atmospheric region, it encounters small air resistance to its motion. Then
A) The satellite's speed will increase, causing it to move to a higher orbit.
B) The satellite's speed will decrease, causing it to move to a lower orbit.
C) The satellite's orbit will remain unaffected, as air resistance has negligible impact on its motion.
D) The satellite will be pulled towards the Earth's surface, leading to a collision.
