I determined the average apparent magnitude to be + 24.9. I then said that the period was 25 days. I used this in the period luminosity relatio...

Re: Circular to Linear

I also used the winch system. However after reading the clarifications and seeing that no gears were allowed...I was wondering does the motor have gears inside of it that would cost points for the task?
