He removes two strips of tape from the roll. He presses each strip of tape, sticky-side down, on a plastic surface.
He quickly removes each strip of tape from the plastic surface.
Ike's teacher tells him that this process has caused each strip of tape to gain a negative electric charge. What could Ike do next to demonstrate that the negative charge of each strip has generated an electric field?

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!
