There is a 1000lb rock sitting on the ledge above the water at a like. If I push it as hard as I can, have I done work? Why or why not?

mistakes are ok

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!

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
