Radio frequency identification

Explanation:

Radio frequency identification is a wireless technology. It involves the use of radio waves in the identification of certain things that is in its range. This involves the use of a tag or antenna which is usually very small in size and a reader for passing of information.

answer: the potential energy decreases from 379 j to 243 j

explanation:

for the law of conservation of energy, the total energy in a system must be conserved. the total energy of the system is given by the sum of kinetic (k) and potential (u) energy:

e = k + u

the total energy is e=675 j, and this does not change.

initially, the kinetic energy is k=296 j, so the potential energy is

at the end, the kinetic energy is k=432 j, so the potential energy is

so, we see that the potential energy has decreased from 379 j to 243 j.
