One way to identify the type of radioactive decay produced in a reaction is to pass the emission through an electric field. Describe the type of radioactive emission produced from the decay of uranium-238 to thorium-234 and its reaction to the electric field.

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head.
