Each of the seeds being blown off the head of a dandelion has a feathery structure called a pappus. The pappus acts like a parachute and enables the seed to be borne by the wind and drift gently to the ground with a terminal velocity. If a seed with its pappus descends straight down at a steady speed, which force acting on the seed has a greater magnitude?

Question
Each of the seeds being blown off the head of a dandelion has a feathery structure called a pappus. The pappus acts like a parachute and enables the seed to be borne by the wind and drift gently to the ground with a terminal velocity. If a seed with its pappus descends straight down at a steady speed, which force acting on the seed has a greater magnitude? O the upward force exerted by the air O it depends on the speed at which the seed descends O The force of gravity O both, force of gravity and upward force of the air, have the same magnitude
