Gselect all of the options that describe characteristics of elastic collisions in closed systems. objects experiencing this type of collision do not stick together after the collision. the total momentum before the collision is more than the total momentum after the collision. the total momentum of the system does not change during the collision. objects involved in this type of collision stick together as a result of the collision.

In an elastic collision:

-- Objects do not stick together after the collision.

-- The total momentum of the system does not change during the collision.  It's the same after the collision as it was before.

0.19 m/s and 0.45 m/s

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!
