A proton of mass 1.67 x 10-27 kg (the charge of a proton is 1.6 x 10-19 C) enters the region between two parallel plates a distance 28.0 cm apart. There is a uniform electric field of 3.00 x 10 V/m between the plates. If the initial speed of the
proton is 5.00 x 10m/s what is it's final speed?

time (seconds)

answer: 0 meters/second^2

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.

i think its c if i'm wrong
