## Answers to the General Science and History Questions

### Key Takeaways

- **Alexander Graham Bell** is widely credited as the primary inventor of the telephone.
- **Astronomy** is the scientific study of celestial objects like planets and stars.
- **Sir Isaac Newton** formulated the universal law of gravitation.
- **Marie Curie** , along with her husband Pierre, discovered the radioactive elements polonium and radium.

The telephone was invented by **Alexander Graham Bell** , who received the first patent for the device in **1876**. While other inventors like **Antonio Meucci** contributed to its development, Bell’s work led to the first practical and commercially successful communication system.

### 🧠 Detailed Answers for the Exercise

Based on the image provided, here are the correct answers to fill in the blanks:

**1. Who is the inventor of the telephone?**

- **Answer:**  **Alexander Graham Bell**. He successfully transmitted the first intelligible speech on March 10, 1876, saying, “Mr. Watson, come here, I want to see you.”

**2. What branch of science studies planets?**

- **Answer:**  **Astronomy**. Specifically, **Planetary Science** (or Planetology) is the sub-discipline that focuses on the formation, evolution, and physical properties of planets.

**3. Who discovered the law of gravity?**

- **Answer:**  **Sir Isaac Newton**. According to the famous story, he was inspired after watching an apple fall from a tree, leading him to conclude that the same force governs both the apple and the moon’s orbit.

**4. Who discovered polonium and radium?**

- **Answer:**  **Marie Curie** and **Pierre Curie**. Marie Curie was the first woman to win a **Nobel Prize** and remains the only person to win Nobel Prizes in two different scientific fields ( **Physics** and **Chemistry** ).

**5. Have you ever conducted an experiment?**

- **Answer:** This is a personal question. You can answer: _“Yes, I have conducted a simple experiment in my science class,”_ or _“No, I haven’t yet, but I would like to.”_

### ❓ Frequently Asked Questions

**1. Was Alexander Graham Bell the only person working on the telephone?**  
No. **Elisha Gray** filed a patent caveat on the same day as Bell, and **Antonio Meucci** is also recognized for his early work on “voice communication” devices.

**2. Is there a difference between Astronomy and Astrology?**  
Yes. **Astronomy** is a rigorous branch of science based on observation and physics. **Astrology** is a belief system that suggests the positions of stars influence human affairs; it is not considered a science.

**3. What is the law of gravity in simple terms?**  
It is the principle that every mass exerts an attractive force on every other mass. The more mass an object has, the stronger its pull.
