An 12 n force is applied to a 1 kg object. what is the magnitude of the objects acceleration?

a=12 m/s²

Explanation:

Newton's second law of motion states that the acceleration of a body is directly proportional to the force applied and takes place in the direction of force.

This can be summarized as: F=ma, where m is the mass of the object on which force F acts. a is the acceleration due to the force applied.

12N= 1kg×a

a=12N/1kg

a=12m/s²

i think the answer is a, hope this is right, that would be my best guess.

snell's law

refractve index = sin incidence / sin refraction
