If the angle is either 0 or 180, that means that there is either negative or positive work, so A and D are not correct.
If the angle is 45, then there is still some work involved.
The only option where there is no work done by a force is B. when the angle is between the force and displacement is 90.
Nonfoliated is the answer I belive.. Hopefully
Answer:
please refer to the attachment above;)
In this case a double displacement reaction will take place.
Crushing a can, breaking glass, cutting paper, boiling water, chopping wood, and mixing water and sand
