A satellite is in circular orbit about Earth at an altitude of 300 km. What are its (a) orbital period, (b) orbital fre quency, and (c) linear speed?

Explanation

To solve the problem, we will calculate the orbital period, orbital frequency, and linear speed of a satellite in a circular orbit at an altitude of 300 km above the Earth's surface.

### Given Data:
- Altitude of the satellite, \( h = 300 \, \text{km} = 300 \times 10^3 \, \text{m} \)
- Radius of the Earth, \( R_E = 6.38 \times 10^6 \, \text{m} \)
- Gravitational constant, \( G = 6.67 \times 10^{-11} \, \text{m}^3/\text{kg} \cdot \text{s}^2 \)
- Mass of the Earth, \( M_E = 5.98 \times 10^{24} \, \text{kg} \)
