HELP ASAP PLSSS Your class is designing electromagnets. Available materials include: various batteries, different sizes of iron nails, and a farge roll
of copper wire. Your group built an electromagnet and collected the following results. What can you infer from their resties?
A) 20 coils is 4 times stronger than 5 coils.

B) Increasing the coils of wire increased the strength of the magnet.
Increasing the coils of wire decreased the strength of the magnet.

C) increasing the coils of wire decreased the strength of the magnet.

D)For every 5 coils of wire added to the electromagnet, the strength of the
magnet doubled

7.study the scenario. a small container of water with a low temperature is poured into a large container of water with a higher temperature. which choice correctly explains what happens to the thermal energy of these systems? the smaller container of water has more heat and thermal energy than the larger container. some heat and thermal energy is transferred to the larger container of water. the larger container of water has more heat and thermal energy than the smaller container. some heat and thermal energy is transferred to the smaller container of water. the larger container of water has more thermal energy and some of that energy is transferred to the colder water in a process known as heating. the smaller container of water has more thermal energy than the larger container, and some of that energy is transferred to the warmer water in a process known as heating.
