Answer : The initial temperature of system 2 is, 
Explanation :
In this problem we assumed that the total energy of the combined systems remains constant.
The mass remains same.
where,
= heat capacity of system 1 = 19.9 J/mole.K
= heat capacity of system 2 = 28.2 J/mole.K
= final temperature of system =
= initial temperature of system 1 =
= initial temperature of system 2 = ?
Now put all the given values in the above formula, we get
Therefore, the initial temperature of system 2 is,

finches that Darwin studied in the Galapagos islands have evolved with
different types of beaks: drilling, cracking, tearing, and fishing. This
is an example of B. adaptive radiation.
These birds have adapted to their environment - they needed to drill, crack plants, fish, etc. so their beaks have changed and adapted so as to fulfill those needs.
Predation is used for hunting smaller animals, warning coloration refers to a change of color, and protective resemblance refers to an animal blending with its surroundings.
