Mr. smith challenged his students to create an electromagnet that will pick up more paper clips than anyone else in the class. timmy is very excited and begins to collect all of the necessary materials. he finds a d-cell battery, an iron nail, and a large roll of copper wire. what could timmy do, using just these materials, to increase the strength of his electromagnet to pick up the maximum amount of paper clips?

c) increase the number of coils of copper he puts around the nail

this is the answer

Explanation:

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!
