Solve the following problem using Coulomb's Law: A piece of Styrofoam has a net charge of -0.004 C and is places 3 meters from a piece of salt with a charge
of -0.003 C. How much electrostatic force is produced?
Is it attraction or repulsion?

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
