If a wire carrying current causes the needle of a compass to move: O A. it disproves Ohm's law.
O B. it proves Ohm's law.
O C. it is an example of an open circuit.
O D. it demonstrates electromagnetism.
SUBN

D. it demonstrates electromagnetism.

Explanation:

If a wire carrying current causes the needle of a compass to move, it is an example of electromagnetism.

The interaction between electric and magnetic fields is termed electromagnetism.

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!

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
