Which statement correctly explains one of Newton's laws of motion? A. Newton's third law states that objects change their motion when a nonzero net force is applied.
B. Newton's third law states that whenever a force acts on an object, that object applies an equal and opposite force back.
C. Newton's second law states that objects change their motion when a nonzero net force is applied.
D. Newton's second law states that whenever a force acts on an object, that object applies an equal and opposite force back.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!
