Yol An autographed baseball rolls off of a 1.2
m high desk and strikes the floor 0.28 m away
from the desk.
How fast was it rolling on the desk before
it fell off? The acceleration of gravity is
9.81 m/s2.
Answer in units of 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!

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

i don't understand. explain it clearly
