- everybody. So for this one, we have roughly how large will this planetary nebula of row before it disperses? So for this, we have d equals the expression rate, okay? And at times, lifetime. Okay, so that is gonna equal 20 kilometers per seconds times. Um, 50 1000 years times we need this into seconds to delete the seconds here. So three point 16 times 10 to 7 seconds, divided by year.

- By the turn of the 20th century advances in photography contributed an important tool for astronomers. Improving photographic materials, long exposures, and new telescope designs produced astronomical images with details not visible at the telescopic eyepiece alone. Remarkably recognizable to astrophotographers today, this stunning image of the star forming …

- So for average velocity, you're gonna to find an average radius. Radius will be equal to velocity times, time on. So this is 3000 kilometers per second, uh, multiplied by time between 2013 and 10. 54. It's 9 59 years times your times to me, approximately three times 10 of the seven seconds per year. So you got a kilometer answer here so and that And that answer is that radius is 8.63 …
