Hello may u pls help me with this I'm hella counfused

Explanation:

(1) Is referring to Newton's first law, an external force (gravitational force) is applied to frogs motion, thus causing it to deviate from a straight line

(2) is referring to Newton's third law of motion, the action force is done by the ball hitting the ground and the direction is downwards, the reaction force is done by the ground transferring that same force to the ball, acting upwards

(3) I think it's also the first law, the person on a train is showing, the force to keep it at rest, the sudden halt of the train causes a reaction force to act on the person, does making the person move

(4) I think it's both Newton's second law and third law motion.

I hope these helps

(1) Is referring to Newton's first law -it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

(2) is referring to Newton's third- law for every action (force) in nature there is an equal and opposite reaction

(3) I think it's also the first law -it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

(4) Newton's second law and third law motion-for every action (force) in nature there is an equal and opposite reaction the acceleration of an object is directly related to the net force and inversely related to its mass

Explanation:

mark me brainy plz

your answer is rna to the question.

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.
