Consult not your fears but your hopes and your dreams. Think not about your frustrations, but about your unfulfilled potential. Concern yourself not with what you tried and failed in, but with what it is still possible for you to do.
This problem is pretty straight forward since we are given
the half time and we simply have to find for the rate constant. The equation
relating the two variable is:
t1/2 = ln(2) / k
where k is the rate constant, therefore:
k = ln(2) / t1/2
k = ln(2) / 14.7 h
<span>k = 0.047 / hour</span>
Answer:this is obviously because free electrons can easily move in the metal due to potential difference, and they are inserted in the wire from the negative terminal of the battery and pulled away ( come back) from the wire into the battery at positive terminal.
