**Diagram Explanation:**

The image illustrates a scenario in physics involving a block on an inclined plane. Here's a detailed breakdown:

1. **Block on Incline:**
   - A block with mass \( m \) is situated on an inclined plane.
   - The block is held at rest by a rope.

2. **Incline Details:**
   - The incline makes an angle \( \theta \) with the horizontal.

3. **Rope:**
   - The rope is parallel to the incline, preventing the block from sliding down.

**Concepts:**
- This setup is often used to study forces in motion, particularly tension in the rope, normal force exerted by the incline, and gravitational components acting on the block.

**Applications:**
- Useful for understanding frictionless surfaces, or introducing friction to study its effects.
- Aids in learning about force decomposition and equilibrium conditions.

**Title: Identifying Forces on an Inclined Plane**

**Question:**

Which of the following forces act on the block *parallel* to the incline? For each force, make sure that the algebraic form of the force is correct. 

*Hint: this problem will be easier if you draw separate force diagrams in your lab notebook, one for the forces parallel to the block, and another for the forces perpendicular to the block.*

**Options:**

- [ ] The force of gravity:
  \( F_{g, \parallel} = mg \cos \theta \)

- [ ] The friction force:
  \( F_s \leq \mu_s mg \sin \theta \)

- [ ] The tension in the string:
  \( T = mg \sin \theta - F_s \)

- [ ] The force of gravity:
  \( F_{g, \parallel} = mg \sin \theta \)

- [ ] The friction force:
  \( F_s \leq \mu_s mg \cos \theta \)

- [ ] The normal force:
  \( N = mg \cos \theta \)

**Explanation of Options:**

- **The force of gravity:** The gravitational force can be split into components parallel and perpendicular to the incline. 

- **The friction force:** This resistive force acts parallel to the surface and opposes the motion of the block.

- **The tension in the string:** If a string is involved, tension acts parallel to the incline.

- **The normal force:** This force acts perpendicular to the surface of the incline.

Understanding the correct algebraic expressions and directions for these forces is crucial in solving physics problems involving inclined planes.
