There is no physical object in space upon which a rocket is able to push off of. nonetheless a rocket is able to accelerate in space. how can this be? explain.

The rocket does not push off the ground. solid or liquid fuel is burnt which results in emission of gases from the nozzle at the bottom. We know from Newton's third law of motion that for every action, there is equal and opposite reaction. The force with which gasses emit leads to an equal amount of force acting on the rocket in opposite direction causing its acceleration.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
