Define newton's second law
when an object puts a force on another object, the second object puts a force back on the first, equal in magnitude but opposite in direction
the total energy through any process is conserved
objects tend to keep their motion unless acted upon by an unbalanced outside force
fnet = ma

Explanation:

Newton's second law states that the acceleration of an object is proportional to the net force exerted on it, according to the formula:

where

is the net force on the object

m is its mass

a is its acceleration

The other statements are wrong because they represent other laws of physics, namely:

When an object puts a force on another object, the second object puts a force back on the first, equal in magnitude but opposite in direction  --> Newton's third law

The total energy through any process is conserved  --> law of conservation of energy

Objects tend to keep their motion unless acted upon by an unbalanced outside force --> Newton's first law

a. are

the answer is 12 as i may remember
