Question
**Required Information**

A spy satellite is in circular orbit around Earth. It makes one revolution in 3.30 hours. The mass of Earth is \(5.974 \times 10^{24}\) kg, the radius of Earth is 6371 km, and the gravitational constant \(G\) is \(6.674 \times 10^{-11} \, \text{N} \cdot \text{m}^2/\text{kg}^2\).

**Question**

How high above Earth’s surface is the satellite?

**Answer**  
__________ km
Transcribed Image Text:**Required Information** A spy satellite is in circular orbit around Earth. It makes one revolution in 3.30 hours. The mass of Earth is \(5.974 \times 10^{24}\) kg, the radius of Earth is 6371 km, and the gravitational constant \(G\) is \(6.674 \times 10^{-11} \, \text{N} \cdot \text{m}^2/\text{kg}^2\). **Question** How high above Earth’s surface is the satellite? **Answer** __________ km
**Problem Statement:**

The orbital speed of Earth about the Sun is \(3.00 \times 10^4\) m/s, and its distance from the Sun is \(1.50 \times 10^{11}\) m. The mass of Earth is approximately \(6.00 \times 10^{24}\) kg, and that of the Sun is \(2.00 \times 10^{30}\) kg. What is the magnitude of the force exerted by the Sun on Earth?

\[ \_\_\_\_\_\_ \times 10^{22} \, \text{N} \]

---

To solve this problem, you can use Newton's law of universal gravitation, which states that the force \(F\) between two masses \(m_1\) and \(m_2\) separated by a distance \(r\) is given by:

\[ F = G \frac{m_1 \cdot m_2}{r^2} \]

where \(G\) is the gravitational constant, approximately \(6.674 \times 10^{-11} \, \text{Nm}^2/\text{kg}^2\).

Given:
- \( m_1 = 6.00 \times 10^{24} \, \text{kg} \) (mass of Earth)
- \( m_2 = 2.00 \times 10^{30} \, \text{kg} \) (mass of the Sun)
- \( r = 1.50 \times 10^{11} \, \text{m} \)

Calculate \( F \) using the formula above.
