T=14.3 d
m₁=38.1 g
t=9.00 d
m₂-?
m₂=2m₁·e^[-(T-t)ln2/T]
m₂=2·38.1·e^[-(14.3-9)ln2/14.3]=58.94 g

Answer:
energy can neither be created nor be destroyed but it can only change from one form to another or transfer from one to another object this is the simplest way of understanding the law of conservation of energy. In simple line its the transfer of energy only.
so now the potential energy is the energy that is in stored form while kinetic energy is that energy which an object contain due to any particular motion.
like a ball is thrown in air so the energy through which it goes upward is kinetic energy and for downward movement of ball it need another energy which is potential energy(in the stored form) and by using this energy it goes downward.
False, there are five forms of matter; solid, liquid, glass, plasma, and <span>Bose-Einstein condensates.
hope this helps :)</span>
Since sodium chloride contains both a metal AND a nonmetal, the combination of those would result in an ionic bond.
Classification systems are mental models that we create to make sorting things simpler and more efficient. We make compromises to emphasize certain details and hide others based on their perceived relevance to achieving the outcomes we seek. Even if the original model was nearly perfect, you should expect the inputs provided and outcomes desired to change as time goes by.
In time, we usually find that we have over-simplified by ignoring important details. Mental models such as classification systems should evolve over time. This enables them to more accurately reflect reality and lead to the outcomes we seek.
You can only find the details you seek by observing the right layer of abstraction.
