Anything over 30 seconds exposure.

You can:

Hold the shutter button down for as long as you want (not advised due to camera shake)
Use a remote release and hold the shutter down on that (better)
Use a remote release and lock the shutter down (better)
Use an intervalometer and set the exact time that you want for the exposure, or multiple exposures, or intervals (can be better for time lapse etc)

Obviously a tripod is required here

maybe, maybe not


I'd suggest you do the thing that boys aren't great at and read the manual
