Answer:

I would say B is the answer.

Explanation:

An applied force is a force that is applied to an object by a person or another object. Example: pushing a box to the other side of a room.

A normal force is a force that surfaces exert to prevent solid objects from passing through each other. Example: resting a book upon a table.

Drag is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This doesn't really match the force we use.

However, an attractive force is a force by which one object attracts another. Example: two magnets pulling/colliding together. This is a good example of a force we exert on objects when it is pulled toward us.

The following tests can determine the mineral in a rock specimen:

1. How does the rock crumble or split under pressure?

2. What is the texture of the rock?

3. Observing it under a magnifying lens.

4. Determine the color of the rock



Test 1 and 3 determines if the rock is granular and the types of grains in the rock. Test 3 also determines if the rock has layers hence sedimentary rock.

Determining whether color of the rock is dark or light also helps identify the mineral and type of rock.
