For a moving object, the force acting on the object varies directly with the objects acceleration. when the force of 81 n acts in a certain object, the acceleration of the object is 9/ms^2. if the force is changed to 63n. what will be the acceleration of the object?

Step-by-step explanation:

It is given that,

For a moving object, the force acting on the object varies directly with the objects acceleration.

When the force of 81 N acts in a certain object, the acceleration of the object is 9/ms^2.

......(1)

If the force is 63 N then,

......(2)

On solving equation (1) and (2), we get :

So, the acceleration of the object is when the force acting on it is 63 N. Hence, this is the required solution.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
