**Conical Pendulum Dynamics**

The figure illustrates a *conical pendulum*, where the bob (the small object at the lower end of the cord) moves in a horizontal circle at constant speed. As the bob rotates, the cord sweeps out a cone. The bob has a mass of 0.018 kg, the string has a length \( L = 0.78 \, \text{m} \) and negligible mass, and the bob follows a circular path with a circumference of 0.75 m.

**Questions:**

(a) What is the tension in the string?

(b) What is the period of the motion?

**Diagram Explanation:**
- The diagram shows a pendulum suspended from a fixed point.
- The cord makes an angle as it moves in a circular path.
- Key elements include:
  - *Cord:* The line from the fixed point to the bob.
  - *Bob:* The mass at the end of the cord.
  - *L:* Length of the cord.
  - *r:* Radius of the circular path.
  - A green circular trajectory shows the path followed by the bob.

**Input Fields:**

(a) [Number Input Box] [Unit Selection]

(b) [Number Input Box] [Unit Selection]
