### Sun and Venus Orbital Mechanics

#### Sun Data
- **Mass, \( m_s \)**: \( 1.98855 \times 10^{30} \) kg
- **Radius, \( r_s \)**: \( 6.9634 \times 10^8 \) m

#### Venus Data
- **Mass, \( m_v \)**: \( 4.8675 \times 10^{24} \) kg
- **Radius, \( r_v \)**: \( 6.0518 \times 10^6 \) m
- **Sun-Venus Mean Separation, \( r_{vs} \)**: \( 1.08159 \times 10^{11} \) m
- **Orbital Period, \( t_0 \)**: 224.701 Earth days

#### Questions

1. **Orbital Speed Calculation**  
   Using the orbital period and the mean center-to-center distance of the planet from the Sun, calculate the orbital speed of Venus as it traces out its annual circle around the Sun. Select the answer that’s closest to the calculation from the list below.

   A) 5571.14 \(\frac{m}{s}\)   
   B) 3.52005 \(\times 10^4 \frac{m}{s}\)  
   C) 2.10027 \(\times 10^6 \frac{m}{s}\)  
   D) 1.26016 \(\times 10^6 \frac{m}{s}\)  
   E) 3.02439 \(\times 10^6 \frac{m}{s}\)  
   F) 3.50045 \(\times 10^4 \frac{m}{s}\)  
   G) 2.97853 \(\times 10^4 \frac{m}{s}\)  

2. **Centripetal Force Calculation**  
   Calculate the centripetal force necessary to hold Venus in its stable, constant-speed orbit. Enter the magnitude of the force in standard units, and do not include the unit in the answer text. Also, you can enter numbers in scientific notation using the convention that the capital letter E represents “10^”, so to enter the number 1.234 × 10^23 you can write 1.234E23.
