The box in the picture begins motionless, and then both forces are applied at the same time. Describe the resulting motion of the box. A) The box will not move. B) The box will move to the left. C) The box will move to the right. D) The box will move to the left and then the right.

Answers

It seems that you have missed to attach the given image for us to answer this question, but anyway, here is the answer. Based on the picture of a box which is motionless, the resulting motion of the box would be option B. The box will move to the left. Hope this answer helps.

The force being applied toward the right is greater. So the box will move in the direction of the greater force being applied. The box will move toward the right. Hope this helps!!!

Explain why each mineral has its own properties, different from every other mineral

Each mineral has its own properties different from other minerals because minerals are made up of different elements. Different elements which can be found on the periodic table all have unique properties, therefore, gold will have distinct properties in comparison with zinc or aluminium for example because they are made up of different elements :))))
