The drag force pushes opposite your motion as you ride a bicycle. if you double your speed, what happens to the magnitude of the drag force? a) the drag force goes up by a factor of 4 b) the drag force stays the same. c) the drag force decreases. d) the drag force doubles as well

Option A

The drag force goes up by a factor of 4

Explanation:

Fact:

Drag force is directly proportional to the square of the velocity of a moving object

Therefore, when drag force pushes opposite to the motion as one rides a bicycle, the magnitude of drag force increases by a factor of 4

i'm just gonna leave this comment here, so i can get a challange done-

explanation:

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
