I KNOW THIS IS IN MATHEMATICS BUT NOBODY ANSWERS IN CHEMISTRY SO I NEED HELP PLEASE!
Mike chose to do a science project on the way that gravity and electricity can both create an attracting force. He set up a model of the Earth-Moon system for part of his project, and then he made an electromagnet with copper wire and an iron core. In his demonstration, he picked up paperclips by waving the electromagnet several inches over the clips on the table. He also explained how the Earth and the Moon each exert a force on the other, causing the tides. A good title for Mike's science project would be ____________.
A. The Solar System and Tides
B. Electromagnets
C. Noncontact Forces
D. Contact Forces
