Estatements are the same for both nuclear reactions and chemical reactions? check all that apply. both can be represented by balanced equations. both involve changes to electron arrangements in atoms. both involve a change in energy. both result in a change in the identities of elements.

Erosion of the beach is normally a slow process. however, in certain situations, large chunks of shore may wash out to sea. what could cause this to happen?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
