### Re: Astronomy C

Also, does anyone know a formula I could use to solve this?

The ratio of orbital velocities for a star to its planet is 0.0083. The system has an inclination derived of
75 degrees, and the mass of the star is 0.66 solar masses. What is the mass of the planet in Jupiter
masses?

### Re: Microbe Mission B/C

I challenge this|[spoiler]Disinfection does not always get rid of microbes that cause disease. Like sanitization, disinfection also serves primarily to reduce, not completely eliminate, pathogens.[/spoiler] Though they both are similar in how they do not kill all of the microbes, sanitization is st...

### Re: Astronomy C

Notice that the apastron is at 2020 and the periastron is at 2070. Therefore, half of the orbit is covered in 50 years, and the total orbit is 100 years (since the orbit is symmetrical along the line through the foci). (I'm not entirely certain that those are in fact the periastron and apastron, bu...

Anyways, another question! 1: Define sanitization, sterilization, and disinfection 2: Name the pros and cons of using each Here...|1. Sanitization and disinfection both mean killing pathogens on things. The difference between that and sterilization is that sterilization renders 100% of all pathogen...
