A coin completes 18 spins in 12 seconds. The centripetal acceleration of the edge of the coin is 2.2 m/s2 The radius of the coin is
V
m.

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.

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

not too sure thinking all accelerations are pointed down
