For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 12 N acts on a certain object, the acceleration of the object is 6 m/s?. If the acceleration of the object becomes 4 m/s, what is the force?

8N

Explanation:

Since Force is proportional to acceleration,

F1/a1=F2/a2

Therefore;

12/6=F2/4

F2=(12*4)/6

=8

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

126 maybe. sorry
