Taro's error is when he stated that the total energy of the ball and the club system is increasing. This is not true. The total energy of the system is not increasing. According to the first law of thermodynamics, <span>total energy of a system is always constant; energy can be transformed from one form to another however it cannot be created or destroyed. </span><span>Energy is conserved. </span>So, for this problem the total energy of the system should remain constant at all times.
Answer:
15 N to the right.
Explanation:
100 N to the right -->
85 N to the left <--
So therefore in order to find the net force of where the sled is being dragged towards is 100 N - 85 N = 15 N.
So the sled is moving towards the right of 15 N.
The dependent in this case would be the type/quality of chairs as that is what you are changing.
<span>The minimum energy required for isomerization is 267 000 J/mol

The isomerization of cis-but-2-ene to trans-but-2-ene requires breaking of the π bond.
The bond energy of a C-C σ bond is 347 kJ/mol.
The bond energy of a C=C double bond (σ + π) is 614 kJ/mol.
So the bond energy of a π bond is (614 – 347) kJ/mol = 267 kJ/mol =
267 000 J/mol.
