The rate of decay at any time (i.e. no. of atoms that disintegrate per second) is directly proportional to the number of radioactive atoms present in the sample at that time.This is known as decay law.
rate of disintegration = -dN/dt ,according to decay law -dN/dt is directly proportional to N,
where N is the no. of radioactive atoms present at the instant of disintegration.

What are the difference between the law of conversation of energy and law of degradation?
The difference between the two is that the law of degradation implies that there is a finite non-zero amount of potential energy that is used cause a process to happen. Recent theory suggests that this is caused by the expanding universe: more energy is converted to potential energy since objects in the universe are moving further and further away from each other. It is possible to create a process that will decrease the entropy of a system (in fact that is how we are able to reach temperatures in the microKelvin range), but the overall entropy of a closed system will always be increasing. This is different from the law of conservation of energy, which does not imply that this quantity exists. In a straight conservation of energy, it is theoretically possible for all the potential energy to converted to kinetic energy and all kinetic energy to be converted to usable potential energy. It is worth noting that the existence of entropy does not make the law of conservation of energy wrong. Think of it this way: the law of degradation of energy is an addition to the law of conservation of energy that states that some of the energy of a system must be stored as unusable potential energy. A real world example would be a middleman in a trade. It is theoretically possible that the middleman could buy items and sell them for the same price. However, the middleman would make no money to support himself and would starve. Therefore, he must buy items and then sell them at a higher price, thereby reserving some of the profit for himself. In this example, money would represent energy and the profit that the middleman makes represents the increasing entropy of the system. The total amount of money in the system stays the same, but the middleman must take some money for every transaction he completes in order for the system to keep functioning.
How does friction affect energy transformations?
It cause degradation of energy transformation. In other word, it loss the efficiency through friction.
What states have energy laws that state that energy can not be created or destroyed?
Law of conservation of energy. Energy can't be created or destroyed is the basic statement of the law of conservation of energy.
Law that states that energy cannot be created or destroyed?
The law of Conservation of Energy. Actually, that law has been superceded now by a slightly different one. Recently (maybe 100 years ago) it was learned that energy can become mass and mass can become energy. So the law had to be modified to say that the total combination of mass and energy can't be created or destroyed.
The law of of energy states that energy cannot be created or destroyed.?
Law of Conservation of energy
What is the difference of law of conservation of energy to law of degradation?
I assume that with the "Law of Degradation" you are referring to the Second Law of Thermodynamics.The First Law of Thermodynamics, also known as Conservation of Energy, tells you that energy can't be created or destroyed - the total amount of energy in a closed system remains constant. The Second Law of Thermodynamics imposes additional restrictions on what can be achieved, and what can't be achieved; specifically, any energy conversion or other change is always done in such a way that a mysterious quantity known as "entropy" increases. That means that there are irreversible processes in nature; with respect to energy, it can also be said that useful energy gets converted into unusable energy. This will continue until there is no more usable energy in the Universe.
