Predict which of the following statements are true or false.
Heisenberg principle is applicable to microscopic objects.

Explanation

To determine whether the statement "Heisenberg principle is applicable to microscopic objects" is true or false, we can analyze the Heisenberg Uncertainty Principle and its implications.

### Step-by-Step Solution:

1. **Understanding Heisenberg's Uncertainty Principle**:
The Heisenberg Uncertainty Principle states that it is impossible to simultaneously know both the exact position and exact momentum of a particle. The more accurately you know one, the less accurately you can know the other.

2. **Applicability of the Principle**:
The principle applies to all objects, but its effects are most noticeable in microscopic particles, such as electrons, protons, and other subatomic particles. For larger objects, the uncertainty in position and momentum becomes negligible.

3. **Significance of the Principle**:
While the principle is valid for all objects, it is particularly significant for microscopic objects where quantum effects dominate. For macroscopic objects (like a baseball or a car), the uncertainties are so small that they can be ignored in practical terms.

4. **Evaluating the Statement**:
The statement claims that the Heisenberg principle is applicable to microscopic objects. Since the principle is indeed applicable to all objects, but is particularly significant for microscopic ones, the statement is misleading.

5. **Conclusion**:
Therefore, the statement "Heisenberg principle is applicable to microscopic objects" is **False**. It is applicable to all objects, but its significance is primarily in the realm of microscopic particles.

### Final Answer:
**False**
