What are the steps that produce electricity from this fuel
deff fn [24]
The nuclear fuel cycle is the series of industrial processes which involve the production of electricity from uranium in nuclear power reactors.
Uranium is a relatively common element that is found throughout the world. It is mined in a number of countries and must be processed before it can be used as fuel for a nuclear reactor.
Fuel removed from a reactor, after it has reached the end of its useful life, can be reprocessed so that most is recycled for new fuel.

What is the system's potential energy when its kinetic energy is equal to 34e?
mixer [17]
Otal energy= PEmax on the spring = KEmax of the oject 
<span>Total Energy= KE+PE at v or x not maximum. </span>

<span>Using the second line </span>
<span>E= 3/4 E + PE </span>
<span>PE = 1/4 E </span>


<span>PEmax =E = 1/2 kA^2 </span>
<span>PE=E/4 = (1/2)kA^2 / 4= kA^2/8 
</span>
