1. Students attached both ends of a long wire to the poles of a battery and wrapped the wire around a spoon. In this arrangement, the spoon is able to pick up five paper clips. The
students wrap more wire around the spoon and want to determine if the strength of the
magnetic force has increased. Which of the following observations would indicate that
wrapping more wire has increased the strength of the electromagnet?
ACE Alko
O A. More wire was needed to wrap around the spoon
B. The spoon now picks up seven paper clips
O C Eventually the battery runs out of energy
D. The ends of the wire must touch the battery's poles

Geologists get to play with chemistry, physics, and history! and what a history you will meet as youwork your way through the course. starting at the beginning, the textbook provides the scientifically acceptedstart of the and promises that you'll get to explore some of the evidence for that scientific view, later inthe semester. meanwhile, which is more nearly correct of the scientifically accepted view? a) the earth formed when the big bang caused older materials to fall together, about 14 billion years ago. b) the earth formed from the falling together of older materials, about 4.6 billion years ago. c) the earth formed in the big bang, about 6000 years ago. d) the earth is eternal, having been here forever and promising to be here forever. e) the earth was assembled by gigantic space beavers, which gnawed down the primordial tree of life andpiled its branches together to form the planet.
