Question
**Transcription for Educational Website** --- **Question 1:** If a star orbits around the center of the Milky Way galaxy in a circle with a radius of 33 kpc, how far does it have to travel (in kilometers) to complete one orbit? [Input box for answer] kilometers --- **Question 2:** If the star orbits around the center of the Milky Way with an orbital speed of about 220 km/sec, how many years will it take to complete one orbit? [Input box for answer] years --- Note: The questions refer to concepts in astrophysics, specifically the calculations for the circumference of a circular orbit and the time period using velocity. - **1 kpc (kiloparsec)** is equivalent to approximately 3.086 x 10^16 kilometers. - The formula for the circumference of a circle: \( C = 2\pi \times \text{radius} \) - To find the time period \( T \), use the formula: \( T = \frac{\text{Circumference}}{\text{Orbital Speed}} \) - Convert the time from seconds to years for the final answer. There are no graphs or diagrams associated with these questions.
