Roller coasters, with their twists, turns, and loops, seem to defy everything we know about how objects move. Roller coaster des
igners use Newton's laws to push people past their usual limits. Which statement identifies Newton's Law of Motion with the correct justification of that law? (DOK 2, AKS 8b)
OA Newton's first law is the law of inertia. Since an object at rest stays at rest, all roller coasters have to be pushed or pulled to get started.
OB. Newton's first law is the law of force and acceleration. Since the rollercoaster is so massive, it will require more force to accelerate
OC. Newton's third law of action-reaction states that for every action, there is an equal and opposite reaction. This means that as you push down on the
seat, the seat does not push back on you with an equal force.
OD. Newton's second law is the law of force and acceleration. Since the rollercoaster is so massive, it will require less force to accelerate.
The genes to be resistant to an antibiotic already exist in the bacteria's genes. Those whose phenotypes are resistant to the antibiotic will survive the antibiotic which kills the other non-antibiotic-resistant bacteria. The surviving bacteria will then asexually reproduce, producing more antibiotic-resistant bacteria.
