Gabriel used an iron nail to build an electromagnet (like the one seen below) that will pick up 4 paper clips. He has tried many changes to increase the strength of his
electromagnet so that it will pick up 10 paper clips?
For each of the following changes, predict and explain the most likely outcome for 2
points each:
• Replacing the iron bolt with a plastic rod
• Increasing the number of coils in the copper wire
• Increasing the size of the battery

Each neuron shown in this figure innervates a group of muscle fibers. what is the term for a group of muscle fibers innervated by a single neuron?

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply. the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
