Question

The question in the picture if it is false you got to repleace

Answer 1

(3)False:a net force causes no change in an object's motion

(4)True: If Manuel exerts a force of 10 N to push a desk to the rigth at the same tiem Lynn exerts a force of 15 n to push the desk to the left , the desk will move to the left

Explanation

Step 1

(3)

Force is a push or pull on an object that produces acceleration in the body on which it acts

Newton's second law states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.

$F=ma$

therefore, the answer is

False a net force causes no change in an object's motion

Step 2

(4)

a) Diagram:

to find the net force, add the vectos( let positive to the rigth)

$\begin{gathered} then \\ (10-15)N=-5N \end{gathered}$

as the net force is negative,object willmove to the left,so

the answer is

True: If Manuel exerts a force of 10 N to push a desk to the rigth at the same tiem Lynn exerts a force of 15 n to push the desk to the left , the desk will move to the left

I hope this helps you
