Respuesta :
1). The feather experiences more air resistance than the elephant and thus reaches a smaller terminal velocity.
FALSE
Elephant has more mass so it will have more air resistance to balance its weight
2). The feather experiences a smaller force of gravity acting on it so will need a smaller amount of air resistance to reach terminal velocity.
TRUE
Due to its less weight it requires less friction force in opposite direction
3). Both the elephant and the feather have the same acceleration due to gravity thus will reach the same terminal velocity.
FALSE
They will have same acceleration due to gravity but the force is different due to their masses so they will have different speed
4). Both elephant and feather have the same force of gravity acting on them, yet the feather experiences greater air resistance.
FALSE
Since they have different masses so force of gravity must be different
5). After reaching terminal velocity both the elephant and the feather have zero acceleration and zero net force.
TRUE
At that instant the velocity becomes constant and net force is zero
6). Both elephant and feather weigh the same amount, yet the greater mass of the feather leads to a smaller acceleration.
FALSE
They cant have same weight as the feather must have less mass so less weight
