To adjust a sprinkler to cover only 180 degrees, locate the adjustment collar or the directional lever on the sprinkler head. Most models have a tab or screw that allows you to limit the arc of the spray; turn or slide this to set the desired angle. Some sprinklers may also have a marked guide indicating the range. Once adjusted, test the sprinkler to ensure it operates within the new range.
There are only 360 degrees in a circle.
because a full circle only has 360 degrees
there are still only 360 degrees in a hexagon
105.8 degrees Fahrenheit. By the way, 'degrees' is generic: they're also degrees Celsius (or centigrade) or Rankin. Only Kelvin aren't called degrees.
4 degrees Celsius is equal to 39.2 degrees Fahrenheit. That's only ten degrees away from freezing.
If the in-ground sprinkler system has not been blown out and it is 30 degrees out, it is important to act quickly to prevent the pipes from freezing and potentially bursting. Contact a professional to blow out the sprinkler system as soon as possible to remove any remaining water and protect the system from winter damage.
Newton's third law of motion. The turning of the sprinkler head is the equal and opposite reaction to the water leaving the sprinkler nozzles. The water goes out and the sprinkler nozzle is pushed backward, turning it in a circle because the arm is attached to the middle of the sprinkler. The higher the water flow, the faster the sprinkler spins.
Jupiter does not really have seasons, since it's axial tilt is only around 3 degrees. It's temperature at the 1 bar level is around 165 degrees Kelvin, around -108 degrees celcius.
Fire sprinkler systems are effectively already zoned - you don't need to do anything special. When your fire sprinkler system detects a fire, it doesn't set off all the sprinkler heads at once. Instead, each fire sprinkler head goes off when the temperature underneath it reaches a specific temperature, meaning only the ones affected by the fire will go off.
winterize it only if you want it to work in the future
A sprinkler pressure vacuum breaker is used to prevent backflow of contaminated water into the clean water supply. It helps maintain proper pressure in a sprinkler system by ensuring that water flows in one direction only, preventing any potential contamination from entering the system.

Yes, each tooth is only 2-4 degrees which you can simply adjust timing to compensate .
There are several ways to come at this answer, most of them way too technical and arcane to bother with. The easiest answer to state and understand may be simply the fact that each parallel of latitude goes all the way around the Earth, but each meridian of longitude only goes half-way around the Earth, so you need more of them to cover the whole Earth. Does that do anything for you ? And by the way . . . there are only 180 degrees of latitude.

You can only adjust the clutch pedal. You can adjust position and range just on top of the pedal.
Yes only slowly it takes about 20 minutes to adjust fully
