PIT_PIT [208]
The first step in the oil extraction process is cleaning the olives and removing the stems, leaves, twigs, and other debris left with the olives. The olives should be washed with water to remove pesticides, dirt, etc.  Rocks and sand will damage a hammermill and quickly wear out a centrifugal decanter or oil separator. ;)

Two forces are applied to a 17kg box, as shown. The box is on a smooth surface
HACTEHA [7]

Answer:

A. the box accelerated to at 1.0 m/s² to the right because the net force is 17N to the right.

Explanation:

To solve this problem, we need to find the net force acting on the body;

   Net force  = Forward force  - Backward force

  Forward force  = 35N

  Backward force  = 18N

 Net force  = 35N  - 18N = 17N

 So;

   Net force  = mass x acceleration

        17  = 17 x acceleration

        Acceleration  = 1m/s²

Therefore, the body moves in the forward direction with an acceleration of  1m/s²
